Got my copy of this Sigma last night and discovered that the manual focus ring is actually an unlabeled Focus/Control ring.

I do believe the R10 is better bang for buck for most use cases, AND I would trade my R7's 33mp for a 24mp if it had faster readout in a heartbeat. But you do realize, if a sensor is out resolving a lens, it's just diminishing returns and the image won't actually be softer lol. If the lens is out resolved it will look the same as the R10, if not out resolved you'll have more detail, that's it. It's not a net negative.

[@simonthibodeau7082]

@@justinburley8659 hard to compare as they are 2 different systems, different copies etc., lots of variables uncontrolled. By the very definition of the physics tho, "over resolving" a lens, can never truly give you a worse image than lower mp, all else being equal of course, assuming the sensors are equally good. Think of it as "you're wasting pixels", not "those extra pixels are softening the image" which cannot be true. Fuji forums went nuts when their 40mp sensors came out for this exact non-issue. Yes it means technically you are not getting "the most" out of the high mp sensor on some lenses. But going as far as saying high mp will look worse, does not make much sense. In a nutshell, if optical sharpness is gonna be the bottleneck of IQ, increasing sensor resolution will give you more and more diminishing returns, not give you an actual, worse looking image. Of course, if NONE of your lenses in your kit can make use of higher mp because none are sharp enough, one might say it makes little sense to go for high mp, so in a sense the R10 is a better "match" and better choice. Still, this lens will perform better overall on an R7 (since it is better in other regards), and will certainly not look worse, at best they will look fairly equal in IQ. In short, high mp on softer lens is just neutral, not a pro nor a con. Only con maybe being, your file sizes are larger "than they would have needed to be" to fully resolve it. Does that make sense? 😅 Hopefully I made it somewhat clear. Btw I do think price/quality wise, many people are better off with the R10 considering how much cheaper it is. I'm not thrashing the R10, many reasons to love it, I'm just saying, objectively, saying it renders softer lenses BETTER is an exaggeration and not true.

[@justinburley8659]

@@simonthibodeau7082 I appreciate the response. I love my R10 and if I could go back and choose again, I would still choose the R10 because I’m perfectly fine with 24 MP. I don’t make huge crops or print photos on a wall quite yet

[@Duncanstibs]

Thanks Chris. Really enjoy your reviews and, in fact, bought this lens on your recommendation. Quick question. I've got an R10 and I'd like to pair the Sigma 18-50mm with a low-aperture background obliterating prime portrait lens. Don't really mind what focal length - will go up to 85 so long as it can take nice head-shots. My budget is about £500-600, and I'm happy to go used. Happy to use an EF mount adaptor also and don't mind the weight. Any recommendations for the best, sharpest glass I can get for the money?

[@Louis-zk4bq]

This !! I need some advice on this too. Id you find anything update me please !

[@Duncanstibs]

​@@Louis-zk4bq So I've done a bit more research. For sharpness I think canons first party rf 50mm lens is probably the best bargain. As for native RF at around glass at 30-35mm that isn't crazy expensive, the choice is either buying the image stabilised canon 35mm 1.8 prime, or waiting for the sigma 1.4. The cannon lens is sharper, though it's a full frame lens so I'm not sure how that sharpness translates to crop. The canon lens also has stabilisation but it's about £200 more expensive. The sigma 1.4 has the wider aperture and a better price, though no stabilisation - and it's not out till later this year. I'm not sure how the EF glass measures up honestly and I'd need to do more research on the sigma art primes. I'd be glad to have more input so @christopherfrost do chime in if you've got any advice.

[@Louis-zk4bq]

@@Duncanstibs I was actually looking for all sorts of lenses lately, and i figured i'd probably go for some kind of telephoto lens, since i've never experienced it, and for portraits the 50mm of the sigma at 2.8 is alright. And yeah i agree with you, if i ever really need something to shoot portraits with a soft bokeh, i'll probably consider the rf 50mm 1.8 or the sigma 56 1.4. I dont really need fast lenses on the 30-35mm focal range. So now i need to choose between the RFS 55-210 and other EF lenses i could adapt on my r50 (EF-S 55-250 IS STM, EF 70-200 f/4 L IS, ...). I'll keep you posted

@@Louis-zk4bq thankyou! Heads up, ended up going for the 2018 tamron sp 35mm 1.4 for the ef mount.

Good luck out there!

[@gal.loh.6174]

Hi Christopher, I use the Canon R7 with the EF-S 17-55, would you say it's worth upgrading to the Sigma 18-50. Unlike the Sigma, the Canon has a stabilizer and also a continuous f/2.8 aperture. What do you think? VG Thomas

[@simonthibodeau7082]

Having used the 17-55 on R7 I'm guessing significant improvements in AF, and honestly the pure IBIS on the R7 might be better than the old OIS on the 17-55 (which wasn't good). Counterintuitively, some old EF glass have such mediocre OIS, that NON-OIS lenses perform better on just IBIS, than the bad sync stab on those. The sigma 18-35 and rf50mm all had better stab than the EFS 17-55 for me. You cannot use that efs17-55 on pure IBIS (no way to set it that way), but I'm pretty sure it'd be better too. Imo a worthy upgrade if not just for just how much lighter it is. But it's definitely a comparison I'd like to see! My guess is, if you do video, definitely upgrade, for stills, only worth it if you value having a lighter lens, but I wouldn't expect significantly better stills.

Everyone’s copies may vary. Some found it on par with 24-105L, some say it’s soft

[@simonthibodeau7082]

Owner of the 18-150 and many L lenses, average sharpness is fair. Average sharpness according to Chris is actually very good, I think you are just hung up on the choice of words, average isn't bad. It's the fact that it's sharp enough for most uses in that small package and throughout the 18-150, for that price, that make it an excellent lens overall. But we don't need to oversell the sharpness either. Sharpness doesn't matter much beyond the level of this lens imo, but we still gotta give credit to those sharper lenses, because, well, they just are sharper. It's definitely no 24-105L btw lol idk who told you that!

​@@dexterinos One is a DSLR lens and the other is a mirrorless, so depending on which system you have you can only use one or the other (unless you adapt the 18-35). The 18-35 is also 3x as heavy as the 18-50. It's kinda like asking if you should buy a normal sedan or a heavy pickup truck. Depending on your needs it should be obvious which one is best for you.

[@simonthibodeau7082]

This 18-50 will be the obvious choice for most.

[@BoReynolds]

Buddy, which lenses WILL work exceptionally well on the R7????

[@christopherfrost]

Very expensive ones :-)

[@zegzbrutal]

RF28 pancake

[@izustun9851]

Finally Canon let the 3rd party lens producers. There is no point to ban them from producing lenses for RF Mount.

[@rossy_0594]

Sigma 18 35 f1.8 vs sigma 18 50 f2.8???

[@aimanramizu6901]

Anyone have the R50 and the older Sigma 17-50mm f2.8 HSM. Do I just keep it and use with the EF - R adapter or should I consider getting the new RF one

[@zegzbrutal]

I have a R50, Sigma 17-70 and this lens. If you don't need video work, keep using your 17-50.

[@raygamma8739]

distortion ?

[@AlexCamful]

Finally!!

[@PneumaticDescent]

Wouldn’t it be just everything if Canon would let Sigma make the 14mm 1.4 in RF tho???

[@VGScreens]

Too late... I already went with Sony instead. Still curious to watch though :)

[@mariaalbi1886]

How is it different from canon 17-55 2.8 Is Usm? If I have the canon, is it worth the change to the sigma for the R7? Is a comparison between these two possible?

[@fotografalexandernikolis]

Bruh look up the size and weight difference.

[@BlendyStick]

The Sigma lens is smaller and lighter while offering comparable optical performance. The old EF-S lens has image stabilization as a bonus, however it is obviously an older system so the R7’s IBIS alone can probably outperform it quite easily. If you already have the Canon lens, it’s probably going to come down to how much the size and weight matter to you.

[@RogSan1892]

I've got the 17-55mm on my 90d. It's a great lens but it's almost as big as my tamron 70-200mm f2.8 g2...

[@niklasd969]

That is a good question I did ask myself as well. Yes it is a lot smaller and lighter. People buying a new lens will definitely go with this one. If want to switch from the old to this one is probably a question if the advantage in weight and size with the loss of IS and focal length is worth the 5xx dollar/euro. Looks like there is not too much difference in optical performance. Sounds like a very personal decision.

[@simonthibodeau7082]

​@@BlendyStick having used it I have little doubt pure IBIS would outperform the old EFS 17-55. Non OIS EF lenses I've tested beat it on pure IBIS. It's a shame we can't switch older OIS lenses to pure IBIS. Great points and I agree AF and weight are really the main reasons you'd wanna upgrade.

[@marijam1924]

so this one doesnt work or canon R or Canon r6??

[@zegzbrutal]

It will work, but in APS-C mode

[@gearoftheweek]

plus RED Komodo and Komodo X owners!

[@criticalpoint7672]

Why would anyone buy a f/2.8 lens only to have to use it at f/4 or even 8 ? Better go with Canon primes like 24, 35, 50 mm, all f/1.8 and get much better results wide open.

[@zegzbrutal]

I'm using this lens for daily, going for f2.8 is perfectly fine. Maybe not good enough for reviewers and keyboard warriors.

[@undifinder6643]

Specify your usage for 1.8, do you shoot landscape at 1.8 and pixel peep literally every single thing? The size, weight, 2.8, first party AF system, and better quality APSC lens for RF-S system is why people buying it.

[@CameMartina]

extreme

[@SixtyFourBlades]

I was excited till I saw it wasn't for full frame 😢

[@rem792]

If I'm right, they only opened the APS-C RF mount for third party manufacturers autofocus lenses, for now.

[@Durio_zibethinus]

With a constant aperture it'd be enormous on fullframe equivalent, at least for my hand 😅

[@paulyeung6608]

would be an amazing zoom range for full-frame cameras haha

[@hunglemed]

Please test on R5

[@stevebell3809]

The r5 is full frame and this lens is for aps- c only

[@vinsensiusrivan3530]

@@stevebell3809 The RF mount on an RF-S lens is identical to the mount on all RF lenses, and RF-S lenses are compatible with all EOS R System cameras. However, full-frame EOS R System cameras, when fitted with an RF-S lens, will automatically crop the image area to match the APS-C coverage of the lens. I think this work on sigma 18-50 too, Chris said it's cropped automatically on his R5

[@garyswergold4096]

The Nikon kit lens 16-50mm is slower b it, cheaper, smaller, has stabilization and is MUCH sharper than either the Canon or Sigma. This lens is a disappointing in comparison

[@justinburley8659]

Is it a constant f/2.8 and good in low light situations?

[@duality921]

what the sigma

[@timlong9913]

Funny how Canon has only relaxed its no third party RF lenses policy for APS-C, not FF....

You’re trying to make it seem as if Canon has fallen off, but fact of the matter is that they are still as popular as ever. People just have more choices now. (And Sony has better marketing. People listen to influencers as if they aren’t paid or given special privileges to present new gear)

@@justinburley8659 No, Canon literally isn't still dominating the market like they were 15 years ago.

canon should have really made their rf apsc 1.5x instead of 1.6x

It's not a great lens for photography, poor sunstars, lot's of chromatic aberration. Good for video though.

[@sunlbx]

This flop is a good background for the coming similar Tamron to shine. Ah, sigma and her bad corners on aps-c f2.8 zooms..... But this time the center is sloppy, too. Wide angle corners are barely usable when stopped down past diffraction limiting aperture.... just wow

[@justinburley8659]

It looks worse on the R7 than any 24 megapixel sensor. For an R10 user like me, I welcome this with open arms. Nothing else is available at this size, weight, and price point

[@sunlbx]

@@justinburley8659 f2.8 will not replace primes for those who value bokeh... especially considering the fact you'll have to stop down to around f3.5 to get acceptably sharp subjects. which isn't too far away from the kit which is kinda sharp-in-the-ballpark also it doesn't go as wide as the kit lens and never really gets sharp at wide angle. i am happy that you are happy to hear about this lens, though! the size was definitely #1 concern when designing this.
