Canon 17-40mm f/4 USM 'L' lens review with samples (full frame and APS-C)

[@robstyles2675]

I just got this for my kit and its tack sharp for my uses. It's actually noticeably sharper than my tamron 2.8 non vc lens and more accurate in autofocus. I am actually suprised. I got this lens for my full frame camera for housing photography but it's a good club photography and event lens for crop sensor cameras. Dont down it until you try it. It's a sharp ass lens for my uses

[@thatmanfromyorkshire]

Had this lens for years,used it on many cameras and now its always on my 5D mk 2. I have other L series lenses but this is my main lens for landscapes. Super lens and great in all weathers. It gets soaked sometimes outdoors, but with a filter on its sealed and never complains. I enjoy this lens and its one of my best purchases...Great for video too!!!

[@miriamadkins9480]

I just bought one for my 5D mark 2! So excited :)

[@thatmanfromyorkshire]

@@miriamadkins9480 good lens,but im back on nikon and have been for 4 years. Enjoy it tho 2😁

[@ilidenstrmrege987]

Really fun to use on my 6D, and the soft corners are negligible in almost all photos.

[@DeckerFI]

7:46 My Tamron 17-50 2.8 Di2 VC went out for warranty repair the SECOND time. So I bought this lens for my 600D. I can tell for certain that: 1. The 17-40 draws a much nicer image than the Tamron. I'd say even including sharpness, but definitely better overall (colours and contrast) 2. The 17-40 is infinitely better built than the Tamron 3. Bought used refurbished from a reputable vendor, the 17-40 cost the same as my Tamron. Also, the 17-40 is a great lens for EF whereas the Tamron is for EF-S, so it serves me after a body upgrade as well. Although generally a good EF-S lens is best for a crop sensor Canon.

[@orckiller91]

I agree, I run this on my 50D and love it.

[@eier3252]

I often heard that the lens is soft (especially in the corners) and I should get the 16-35 f4L instead. I went for this, used at €399, and I love it a lot. My copy seems to be exceptionally sharp, even my corners at 17mm and f5.6 or 8 are really sharp. Also, you'll get razor sharp extreme corners if you take two shots with a little varied focus and combining them in Photoshop, because its focus plane isn't a flat plane, but a little more in the front in the extreme corners, which cause the blurry corners. Its color rendering is also very good, sometimes even "too" good so that I have to turn down saturation/vibrance a little in post. Also notable is that the lens is parfocal, so the focus stays the same when zooming. Very good for video, and for some funky long exposure where you zoom in/out while taking the shot.

[@robstyles2675]

Same there must be variance and copies. I got this lens over the weekend and shot 4 events and a small fun photoshoot. Its absolutely sharper than tamron 2.8 non vc and much more accurate in autofocus and sharp across the frame. I am not sure why some ppl dont get a good copy but I really trying to find flaws but it's better than tamron for sure. Its sharp and has more of that 3d effect than the tamron and colors pop more. I think ppl should try the lens before passing judgement

[@NomadicNative]

Even with its shortcomings in optical performance and no IS, this lens performs well on my M50 for video. I was surprised to see how soft the image was at 17mm on the APS-C sensor as this has not been my experience with this lens.

[@Mr.Monta77]

I got a mint 17-40mm F4 L for $200 in 2024. I have rarely had any gear with higher value/quality for the price. I strongly recommend this lens for anyone not dependent on IS.

[@Ivlodded]

Just bought this lens used for 200 bucks and put it on my 6d, 1ds2 and 5d Im absolutely satisfied for that cheap price

[@dougsholly9323]

I know this is 8 years old, but it popped up in my recommended as I was considering getting one of these lens. I only wanted to say that any difference in picture quality between a full frame and a aps-c is entirely attributable to the camera. The lens won't suddenly change its optics hooked to a different frame. It is probably 'soft' on the aps-c because the AF isn't calibrated, or possibly even user error.

[@vultures166]

It has to do with the size of the pixels on the sensor, and the pixels tend to be a lot smaller on APSC cameras than on FF cameras. In this case about 2.5x smaller. This has a dramatic effect on the tolerance for optical errors produced by the lens.

[@bjornvansteenbergen5055]

Hi Christopher! Ive taken your review into account but decided to go with the 17-40mm anyway. Have to say, its a very good lens with some drawbacks you'll have to live with. It lives on my fullframe camera, but at night it's wonderful on crop. Just remember to close down the aperture and bring a tripod.

[@nikonmark37814]

Yes there are other lenses but I paid US $400.00 in 2020 for a LN lens, the alternative was the 16-34 f4L IS but it's more than double the cost which I can't justify because I'm not a wide angle shooter unless I'm doing the occasional landscape and the images I get with 6D and 70D are quite pleasing to me if I don't use the lens wide open. But the lens isn't as good as the 6D when I'm using my 5Ds so I use fast primes with that body.

[@romsampaga8354]

Hi, Chris! Please continue doing your lens reviews. I always check your reviews whenever I'm curious about a lens. Thanks a lot! :)

[@DizzyBob1]

Great review, I have seen alot of different lens reviews on KZbin this is one of the best and most informative I have seen, keep up the good work!

[@hereiam2005]

Disclaimer: I do own the 17-40 on a 5D (Mk1), but I do not own a crop sensor camera. I plan to buy one, however, since I think that instead of buying 2 lenses, why not 2 body and let the crop factor do the rest :D So half of my comment is just my conjectures. While I agree with the reduction in resolution due to higher pixel density in a crop sensor body, the reduction in contrast is very strange to say the least. A full frame (FF) lens on a crop sensor body is the same as the same lens on a FF body and crop the result (to the crop factor). So logically, while resolution may be different, color rendition and contrast must be precisely the same on both body ( the center of a FF to be precise). Could you double check your result?

[@Deus_Ex_1]

Thx for the input, until I found your comment I thought I was the only one wondering why the quality in the corners were lower with a higher definition sensor (6D vs 60D being 18mega pixel vs 20 for the 6D); I didnt think about the sensor resolution (pixel density) being higher for the 60D hence the better results on the tiles at the upper left being better.

[@TheHifiSound]

Hi Chris, Will it be possible to test it on a newer Canon body like R5 ? Thanks !

[@oliverweber6842]

I've been looking for a very good lens to use on my old Canon EOS 10D out of the year 2003. As you mentioned in your video that old DSLR came with only 6,3 MP ... so that old lens fits perfectly to that APS-C size sensor cutting out all problems on full-frame corner. I'm used to work with my EF 24-105 f/4 L ... so it's no problem at all not having a faster aperture available. Sometimes it's better NOT to loose sharpness witch very fast lenses tending to. Some guys use that lens on EOS 7D for example which I would not recommend as well.

[@srinivasanraghavan88]

I am testing with my 5ds .. Same experience for corner sharpness.. But only at the very edges stopping down to f9 . But the amount detail it resolves is impressive and resistance to flaring . If one has money and serious about landscape photography one should get 16-35 f4l IS .. but wide angle zoom which could very handy and important this lens is the best on a budget

[@robertocuevas7873]

Hello Chris, great reviews. About the 17-40, I think you just got a bad copy. I own one and its fantastic for landscape, which is my favorite type of photography. In fact, I like it even more with my APS-C camera (where its most of the time) as its using the center of the lens, which is extremely sharp, almost corner to corner. And don't forget the colors, contrast and saturation you get with this lens, it is famous for it!

[@mazzfotovideo]

Works with Sigma mc-11 on Sony a7r? Thanks

[@luf-produkttests]

I usually shoot at f/5.6-8 or sometimes 11 and get great results on the 17-40mm, definitely L lens quality with some pitfalls as you mentioned. Overall a great lens in your bag.

Great video ton of information to help make your mind up to go get this lens!

[@Ineedahandle75]

I have a dilemma. I own this lens and also the EF 20-35mm f/2.8L and love them both...however I don't need both. Would love to keep both, but can't justify it, so one has to go but it's an impossible decision. On the one hand I never really need anything wider than 20mm and I love the metal build quality and feel of the older lens. But I am very fond of the 17-40mm too.

[@cjonwickham1933]

Keep both...one daily other night or indoors...or for 2nd body or backup other break...just store it safe place.

[@adriaanrijkse]

Dear Christopher frost, i own a canon 70D, and i want the best possible image quality for travel photography at daylight. (no ultra zoom needed), what do you recommend? Thanks in advance! Adrian

[@christopherfrost]

I like the Canon 15-85 a lot. If you want more zoom range then the 18-135 STM is also good (but I prefer a lens with a wider angle)

[@adriaanrijkse]

+Christopher Frost Photography Thanks a lot for the fast reply, i was thinking about getting the 17-55 mm f. 2.8, but for travel this lens is better you say? Is the image quality comparable in daylight? Thanks in advance !

[@christopherfrost]

Both lenses are great for daylight shooting. The 15-85 simply has a better zoom range. All the best!

[@BEairsoftTV]

Great review again, Christopher!

[@EcoHabitat00]

I always enjoy your videos. Great advise when it comes to making desitions on what lenses to buy according to personal needs and budget. Thanks for sharing.

[@Dutchrail]

Hi Christopher! I'm kind of wishing you had a better review of this lens ;). I'm shooting with both a crop (60d) and a full frame (5d mk1) body, and I am looking for an ultra-wide lens as I found out I shot 50% of my photos at 15mm on the 60d. (22mm full frame equivalent). Canon only has a few ultra wide lenses being the 17-40 f/4 and the 16-35 f/2.8. Both would act like an ultrawide zoom on the 5d and more of a standard zoom on the 60d. For my situation, would you consider the additional image quality to be worth another $700? I am expecting to shoot mainly outside or on a tripod.

[@christopherfrost]

Have you tried the Sigma 12-24mm? It works as ultra wide on both full frame and APS-C :-)

[@Dutchrail]

Christopher Frost Photography I'm also considering the Tokina 16-28mm, reported to have excellent image quality but of course it's shorter and it weighs twice as much as the 17-40. An option would be to use the 17-40 as an ultrawide walkaround on the 5d, and a prime on the 60d. If I use the 17-40 on the 60d I need to limit myself to f/8 and higher which is acceptable for outside work; landscapes, sunrises and sunsets. I'll go look into the Sigma next!

[@bandaralhazemi7751]

Best Reviews Ever. Keep It Up.

[@YouFillMyDreams]

Hey Chris! I am fairly new to photography, I've been doing it for awhile but I've only recently started taking it seriously and learning more about it and how to use cameras without the auto mode on. I own a 600d and have the kit lens and the 40mm STM lens. I have come into a little bit of money recently and am considering purchasing the 70-200 f4 non is. It's £450 pound on amazon and I think that's an absolute bargain for what the lens does. I was just wondering if you would recommend buying it or maybe what lenses I should have in my collection, and what accessories I should own. I am interested in photographing nature and wildlife, landscapes, sunsets and buildings etc. I am also looking at the 100mm 2.8 macro lens, as I love macro photography. I would just like some advice on what lenses and general kit I should own and what lenses would be useful to me. I am doing photography at my school and have already done it for my DofE. Thanks for reading, any advice would be appreciated. Warm regards, Euan

[@christopherfrost]

Hiya. I would say, consider getting a couple of different lenses rather than spending 70-200 f/4 non-IS, which is a hard lens to use for beginners (it's much better to have a telephoto lens with image stabilization). Grab a Canon 55-250mm IS on eBay to practice on as your telephoto lens and see how you do. And with that, get an ultrawide angle lens like the Sigma 10-20mm f/4-5.6, or for even more fun, the Samyang 8mm f/3.5 fisheye. The 100mm 2.8 macro is fun and it works nice as a portrait lens too - check out my reviews of all those lenses

[@BussEnthusiast]

[@christopherfrost]

Yup! Just to boost colours and contrast a little.

hi, im relatively new to photography and video. i dont own a super high end camera, i have a Canon SL1. im not sure what you mean by "full frame" camera which im assuming mine is not but i was wondering if this lens would work well with it? i heard you say this is an ultra wide angle lens which is what im looking for. i take a lot of ourdoor wilderness shots and stuff like that and dont have any lens thats wide enough to get large areas, i live in florida so i take a lot of photos in the everglades. i have the 18-55 kit lens and also the 55-200 stm lens but bother arent wide enough for what i need. any help would be appreciated

[@christopherfrost]

PYROAirsoft You have an APS-C camera. Do not get this lens (as you'll see from this video, it doesn't perform so great on APS-C). Try the Canon 10-18mm IS STM :-)

[@littleLexi456]

Hi Chris, currently I have a 600D but I want to upgrade to full frame. I'm not sure if I should buy a 6D or a 24-70mm f/2.8. The reason I want to upgrade to full frame so badly is because lately I've been a bit OCD when it comes to the crop frame sensor and it has been getting on my nerves.

[@christopherfrost]

You mean, you can either afford a new lens, or a new camera? Get the 6D, it's worth it. Get a 50mm f/1.8, and find a cheap Canon 24-85mm f/3.5-4.5 USM on eBay until you can afford a better lens

[@littleLexi456]

Christopher Frost Photography I have the 50mm f/1.8 and i might have a few hundred extra but the nifty fifty is my only ef lens.

[@christopherfrost]

littleLexi456 Well, the 24-85mm USM is a very nice, cheap lens for full frame cameras, you can often find it for £60, and it would hold you until you could get something better :-)

[@jethrobodine4638]

i have purchased the new canon 70D, i was torn between the 17-40mm and the new 17-55m EF-S lens. I have watched both your reviews on these lenses and it seems you would prefer the EF-S lens? am I correct? I already purchased the 10-22mm canon as well for outdoor work/landscapes.

[@christopherfrost]

The 17-55 f/2.8 IS would be much, much better

[@jethrobodine4638]

thanks for the information, I just bought the 17-55 f 2.8 and excited about trying it out.....

[@youssefhiggins.6945]

Would you suggest to take photos, as wide as possible and then crop them in for the sharpest results and to avoid those blurry edges.

[@christopherfrost]

It's an idea, but then you won't be getting a 17mm image anymore so it slightly defeats the point

[@ilidenstrmrege987]

Ideally you'd have less detailed stuff in the corners anyway, such as the sky, so the softness there can be mostly ignored

[@mrnomore]

Hi Chris. I wonder one thing...was the corner softness in all 4 corners?

[@christopherfrost]

Yes. It largely depends on how well-centred the lens is

[@christopherfrost]

You could do. The 10-18 will actually give you sharper pictures, though

[@emmanuelnalli]

thanks for help

[@spacexjournals]

Chris, Is there a high quality wide-angle lens for APS-C cameras that you would recommend. I was thinking of getting this for my landscape photography (with my Rebel t3i), but based on your review i think you would recommend something else. Any wide-angle lenses that are close to L photo quality for an APS-C?

[@christopherfrost]

If you want ultra-wide angle, then the new Canon 10-18mm STM is very good, although it obviously doesn't have a great zoom range

[@Iuohaewfiuvlawe]

For APS-C, the best choose for a lens to equal (and even overcome) L lenses is canon 17-55mm f2.8. It's not an ultrawide angle, just slightly wider than the kit lens, but is amazing due to great quality at f2.8 (almost better than canon more expensive 24-70mm f2.8), and also has an image stabiliser included ( what canon L f2.8 standard lenses don`t provide).

[@jsjw2]

Hi Chris, I have a 5d classic and thinking about getting a wide angle lens, my camera's high ISO practically doesn't exist (up only to 1600), would you think this one is a good choice?

[@christopherfrost]

It's not a bad choice. It might be worth looking at the Tamron 15-30 f/2.8 VC, if you're willing to save up a bit more.

Go for the Tamron, or even better, get the Sigma 17-50 f/2.8 OS HSM

go for sigma as chris said but if you can find canon 17 55 2.8 then go for it , it is best out of three in this category

[@SeanP7195]

I'm going to Rome and Budapest in a few months and am wanting to take some nice wide angle shots. I'm a photo enthusiast with limited equipment and was thinking about getting this lens. Could you recommend this investment for that or another?

[@christopherfrost]

Just to check, you're using a full frame camera, right? Ultra wide angle options are slightly limited. I'd recommend this lens, or the Tokina 16-28 f/2.8. It's a tiny bit less sharp and the zoom range is more limited. But it lets in twice as much light, and it has less barrel distortion at 16mm which is a huge bonus. The only problem is that Tokina's quality control is poor, and if you send a lens away to them for fixing then it can take them a long time to get it back to you (mine took about 2-3 months)

hi, can you do a review from Tokina 16-28mm f/2.8 AT X please??? i'm been thinking in buy one, but first i want to know more about the quality and sharpness, i saw a few videos on youtube, but nothing better than your reviews, greetings!!

[@godz2928]

What aperture is the sharpest it can get?

[@abdulkather6748]

Brother pls review the tokino 17-35mm f/4 FX lens for canon...pls for me

[@zenza7120]

hello chris, I think it would be very interesting review for sony a7 shooters if you compare some budget - affordable UWA zooms such as Canon 17-40 and Tamron 17-35... The only UWA zoom is so far fe 16-35 which is very expensive for so many....

[@tomed09]

Just bought one for my back up camera(5D Mkiv) Main camera is R6 Mkii

[@TheGhostplanner]

I am searching for an inexpensive lens with good quality for Real Estate photography. Would appreciate not too much distortion. Would this be a good lens or would you recommend something else?

[@richmck007]

Hi, you say the 15-85 is a good lens, but how does the 24-70 f/4 L lens rate in comparison to that..? I ask as I am looking at buying the L lens , however your brilliant video has made me think otherwise... Until you post a review on the 24-70 f/4 L I will be searching the net for comparisons! What say ye, Chris..!?!

[@amog2013]

The canon 24-70mm is an ef lens which means on your crop senor it will have a focal length of 38-112mm.

[@richmck007]

amog2013, would that mean that this lens is not ideal for a canon 70d ? And what about the 24-105 f/4 L ? Usable with the 70d... Thank you for taking the time to write a post. Your photos by the way are very interesting! Many thanks

[@amog2013]

rich Mck Your 7OD, which I also have, uses EF-S lens although EF will also work. I have the efs 15-85mm lens which a very good lens. The Sigma 18-35mm f1.8 is the sharpest lens you can get for a crop sensor (70D is a crop sensor). The focal length on the Sigma is not much though. The Canon 15-85 is a better all rounder.

[@amog2013]

rich Mck L lens are designed for full frame cameras (Canon 6D, 5D mark iii). You would be better off buying EFS lens. Although the Canon ef 70-300mm f5.6 works really well on the 70D, but only if you shoot sports or far away objects. I think a Canon efs 15-85mm f3.5- 5.6 could be what u are looking for. Watch a few reviews of it.

[@1MSTV]

Keep up the great work!!

[@hungrypanda7]

will this lens be good for shooting portraits? I'm currently looking for a decent but not too expensive portrait lens.

[@christopherfrost]

Eric C No. You need a lens in the 50-200mm focal range with a fast aperture, like f/1.4 or f/2

[@mcdonalds1499]

Thank you. I own 60d and this vid. Really helpful

[@christofferlindvall4128]

When Will you review the Canon 17-35 f2.8L USM @christopherfrost?

[@JadenWhite]

Lens is currently 500 USD new.... Considering it. Half the price of the 16-35 is f4

[@KennLau]

Hi Chris, thanks for the thorough review. Have you tested the Tokina AT-X 17-35mm/f4 Pro FX lens on your 6D? What are your thoughts on the Tokina? I'm thinking of trading my EF-S 10-22mm/f3.5-4.5 USM for the EF 17-40mm/f4L USM. However, I'm starting to suspect that the EF 17-40mm/f4L might not be such a good buy after all.

[@christopherfrost]

I've heard that the Tokina f/4 isn't too great, but the Tokina 16-28mm f/2.8 is meant to be very good

[@KennLau]

I may just keep the EF-S 10-22mm after all since I'd always have a cropped sensor body as a backup. Something tells me the EF 17-40mm is not good value.

[@buddypal2465]

Weird, I've never had those problems with mine but this is still a great review

[@robstyles2675]

Same I used this lens extensively over the weekend and its ridiculously sharp compared to my old tamron 2.8 and it even seems brighter. F 4 on tamron is darker than F 4 on this lens. I am actually very suprised I wasnt expecting to be noticable difference on APSC and for me it is a marked improvement.

[@robstyles2675]

I picked it up second hand for 250 bucks

[@mohammadshadid44]

can i use it for film shooting?

[@VuNguyen-sp9py]

Very clearly review, is the house in the review yours? ^_^

[@Threetowerstactical]

^ what this guy said

[@romainmaletphotographie]

Hi thx for all yours videos ! I ve a question please I m hesitating with the samyang 16mm and tokina 11 20 only for landscape photography on my 80D I m only asking for image quality thx for your answer I was thinking about 17 40 but after your video I m changing my mind :-)

[@christopherfrost]

You'll find the 11-20 far more flexible

[@MikeDKelley]

Sigh -- more questions (but thanks for your quick answer last time :>). Someone on another forum recommended this to me versus the 17-55 2.8. There's a bit of a price difference (less than $100) between them, so that's not a factor. As you might remember, I want to use whatever lens I get as my general purpose lens on a 70D, so not full frame. Right now my favorite lens for this purpose (well, on another APS-C camera -- haven't got the 70D yet) is the 28-70 2.8 L, so I wouldn't miss so much the lack of wide angle (and might appreciate the longer reach). But loosing a stop really worries me, and not even so much for light (although that's part of it to be sure) as it is for getting the background out of focus. I guess my question to you would be: how would you compare image quality between the two lenses, and do you think the build of the 17-55 is "good enough" compared to an L series build. Image quality is a function of the shooter, I understand that, but I can use all the help I can get, and that (plus out of focus background) are the two things I'm really looking for in a lens. TIA for any help.

[@christopherfrost]

The 17-55 really is considerably better in terms of picture quality and is pretty much the best general purpose lens for just about any APS-C camera on the planet. Take a look at my reviews of both lenses - you'll be able to see the differences in my standardized tests :-) I definitely wouldn't use the 17-40 on an APS-C camera - as you can see in this review, it just doesn't cut it.

[@MikeDKelley]

Christopher Frost Photography Thanks again for such a prompt and helpful reply. You've done a tremendous amount to put my mind at ease (Canon ought to give you a commission -- or at least a free lens -- for all the great work you do on your KZbin channel). I'm definitely convinced the 17-55 is the right lens for me and I'm excited to get back into the digital SLR world after a decade off.

[@christopherfrost]

I miss my old 17-55, it's a wonderful lens :-)

[@MikeDKelley]

Christopher Frost Photography That begs the question: what do *you* use as your "walking around" lens on your APS-C camera? (I say that because watching so many of your reviews and reading comments I'm not sure at this point whether you still have a 70D or are back to your venerable 60D). I saw your review of the 55-250 and I'm definitely getting that as well, but it's a bit too long (particularly on a crop sensor) to carry on its own even just for fun stuff. I'm thinking there will be days when I might want to go out and travel light, nothing serious but still have the ability and versatility to do video and stills (and perhaps even a bit of macro work) and not carry around more than two lenses (and small ones) at the most. But I'm still in the dilemma of needing IS if I do any video (so carrying around one of the nice Canon pancakes probably isn't a good option for me).

[@christopherfrost]

Mike Kelley These days I don't really use APS-C, although I love to use my 70D for video work. If I only had one lens for APS-C it would be the Canon 17-55 f/2.8 IS USM, although I'm also a big fan of the Sigma 18-35 f/1.8 :-)

[@monstermayank]

Nice review, how is it compared to Tokina 16-28 f2.8 ?

[@christopherfrost]

+Monstermayank Haven't tested the Tokina, I'm afraid

[@monstermayank]

Thanks for replying, I am looking for a UWA for to be used for wedding photography and occasional landscape and tight places. Since it wont be used much I can't justify the their price, was curious how is it for professional ork or 16-35 f/4 is worth the extra price.

[@christopherfrost]

+Monstermayank I'd go for the Tamron 15-30 if I were you - that would be my choice for an UWA full-frame lens :-)

[@monstermayank]

Thanks Chirstopher, will check that out. :)

[@hihi2998]

Hi are there any issues if I buy this lense for a camera which is not full frame?

[@christopherfrost]

Watch this review, and you'll see how well it performs on an APS-C camera

[@SynthieFlowers]

Should I buy this for my 70d? my kit lens broke and am looking for a new one.

[@christopherfrost]

If you watch this video, you'll see all about how the lens performs on an APS-C camera

[@rodrigo4379]

does it worth 450 euros used? great video ! and what other lens you recommend (something wide like this one)

[@christopherfrost]

Hmm, I would want to get it slightly cheaper than that, really - it's a bit of an old lens nowadays

[@chrisleon4153]

hello chris, better Canon 17-40mm f/4 L or Canon 24-70mm F/4 IS USM L? thanks!

[@christopherfrost]

Depends whether you need a wide-angle or standard zoom lens

[@chrisleon4153]

+Christopher Frost Photography hmm i see, if i used for wedding photography, canon 24-70mm F/4 IS USM L would be great?

[@christopherfrost]

For wedding photography you really should use a lens with at least f/2.8 as its maximum aperture

[@pl3xuz3]

Chris, you forgot to mention that this lens doesn't have IS image stabilization. Otherwise excellent review as always. You got a like again :)
