Sigma 28-45mm f/1.8 DG DN 'Art' lens review

[@tomasocarbone]

Wow, the sharpness of wide open is honestly impressive, it is shocking how insane lens resolution has come in the last decade or so. I remember being super excited about how sharp the Zeiss Otus 50mm 1.4 was when it came out. Now we have similar level of sharpness in 1.8 zoom lenses..! what a time to be a photography enthusiast :)

[@sickheadache9903]

Zeiss never made a 50mm 1.4 Otus. They made a 55mm 1.4. I used the Otus 55 1.4 and was amazed but when Sigma made a 50mm 1.4 Art..for the cost..I truly was amazed. And still today use the Sigma Art Line!

[@tomasocarbone]

@@sickheadache9903 yes right, it was a 55!

[@Stop-All-War]

Sigma Art 40mm was virtually equal to Zeiss Otus 55mm in image quality in testing but few people bought it.. it's safe to say that lens is a hidden gem & used now, can be bought for £400

Amazing as usual! Both Sigma and Frost’s detailed reviews! This lens is perfect for those who prefer a wider look to portraits. 45 1.8 is so close to 50 1.8, and the latter is basically ubiquitous for photographers. I’m so happy I pursued the DG DN lenses since they’re just as high quality as 1st party lenses, except their much cheaper, slightly heavier, and have (in my opinion) gorgeous build quality. Focus and aperture rings turn soooo smoothly.

The 28-45 has more pincushion on the long end but less barrel distortion on the wide end. Overall the Full Frame image plus extra sharpness of the new lens is going to blow the old APS-C lens out of the water. Sigma needs to update the 18-35, I wouldn't hesitate to buy an updated model for my R7 if they did (and assuming Canon allowed Sigma to release such a lens on R mount).

[@maggnet4829]

Wow, you got it for testing so early. Awesome! What is missing is the crop mode, especially for a lens that ends at 45mm but has a sharp center I think this matters. It effectively transforms this lens into a 28mm-62mm. Fun fact, that's about the focal length of the tiny 28-60mm from Sony.

I've been using the Sigma Art 40mm f/1.4 DG HSM on Sony for a while now. It's very large and very heavy, but optically stunning. Probably one of the best lenses ever made. This could probably replace it. It weighs less, is about the same length, can zoom (internally, too), is quite sharp (obviously not as good as the 40mm, but still very good for most of what I do), and the only downside is f/1.8 instead of f/1.4.

[@nickorafael3887]

[@hendrickziegler8487]

You'd need a 28mm f/1.1 or so to get the same shallow depth of field as a 45mm f/1.8. The Sigma 28mm f/1.4 would get you an equivalent of 45mm f/2.2 or. So, yeah that lens is cheaper and a smidge lighter? Horses for courses I guess. This zoom seems good if you care about resolution, or are a photo & video shooter.

I think this is a really PERFECT choice for people who really enjoys using his 35mm like a main lens, but sometimes wants to make little zoom adjustments. Obviously this lens is a great competitor for that 28-70 f2, because of the price and that lovely aperture ring. Sigma is a perfect company, making really awesome options for way better price.

[@MattTrevett]

35mm is my favorite, but the only lenses I have which cover it are Sony 24-105 f/4 and Tamron 35-150. Both are fantastic, but I'd be curious to see how this lens compares. A tad larger aperture than the Sony and a fair bit smaller than the Tamron.

[@Xirpzy]

Yeah. Im considering getting the 24-105mm f4 just because its smaller and I tend to find 28mm to not be wide enough and 70mm not long enough. Not much point in a zoom if the focal range is so small.

[@zbieraj]

The problem is that for the same price, you can get the Tamron 35-150mm f/2.0-2.8. An important note: in the 35-45mm range, the Tamron still maintains an f/2.0 aperture (it only goes to f/2.2 at 50mm). It is 5mm longer and 215g heavier than the Sigma. Additionally, the Tamron 25-50mm f/2.0 is coming, which according to rumors, will be half the size, half the weight, and half the price of the Sigma 28-45mm f/1.8. And Sony is about to release Sony 24-70mm f/2.0 for the price (again, rumors) between this Sigma and Canon 28-70mm f/2.0. While it is the brightest full-frame zoom ever made, it doesn't offer enough in terms of range, size, and weight to be truly competitive with what's already available on the market, especially considering what's about to be released (such as the aforementioned Tamron 25-50mm f/2.0).

[@xenonsens]

Any Rumors of when the Tamron Lena will be released?

[@zbieraj]

@@xenonsens Mid-2024-ish. Both Tamron and that f/2.0 Sony.

[@joostkuijper6272]

This is wrong. The Tamron 35-150mm does f/2.0 up to 39mm, and f/2.2 up to 59mm, and f/2.5 up to 79mm. So at 45mm you won't get f/2.0 with the Tamron, but f/2.2, making the difference two thirds of a stop compared to the Sigma 28-45mm at 45mm. Furthermore: the advantage if the Sigma is nut just numbers about max aperture (brighter) and range (wider, not having 28mm but only 35mm is a thing), but the main advantage is the stunning IQ. Of course, the Tamron has more range, but for IQ it's only close to primes, whereas the Sigma simply beats most of the primes. It's a beyond zoom performance lens. Therefor the Sigma shouldn't be compared to zooms as if it would be an inflexible short range zoom, it should actually be compared to primes, as being the "most flexible prime" ever. The Sigma is waaaay more flexible than a 35mm prime, while at the same time the IQ is at the same level. The Tamron is amongst the best zooms, but nothing more than that, and beyond 120 or 135mm or so it can't compete wide open with most 70-200mm f/2.8 lenses. And if I would have both lenses I would change to the Sigma for the 35-45mm shots, to get true prime IQ.

[@sorek__]

Superb lens. I had 18-35mm f1.8 with speedbooster back in GH4 days and I loved this lens, this seems to be obvious upgrade for FF lenses. Only problem is price but I can replace so many lenses I own (especially 40mm f2.5 from sony) that this is totally something I need.

[@JohnAudioTech]

Impressive lens! I'd wish it could have around a 2x zoom range, say, 24-50 or 28-60 but I'm sure it is very difficult the make a fast zoom FF lens with such a range.

Not that I'll likely ever get to use it, but I think this is the first lens I've seen in a long while that has a price point I can at least understand. A more zoomed in lens would be my ideal follow-up to this. Something around 50-100mm. Is it always true that a lens performing well on full frame will be equally as good or better on a compact sensor?

[@nat-lj8kt]

Hats off to Sigma. Only real downside is size+weight which is expected and is a result of physics. As a 24-70 GM II user, I would not replace 24mm and 70mm but this is a different, very strong product with unique parameters in a saturated market where everyone can design good lenses but it's a matter of cost and quality.

[@christianschneiderphoto]

Impressive to say the least. Canon user here past 20 years, don’t care about what lens brand I have, as long as it makes me look good. My sigma 50mm EF with RF adapter is my go to. But I can’t really understand the focal lengths here. Sure it can replace some primes but still a zoom range that’s to me pretty pointless. But the day when 24-70 comes in a 1.8 that’ll be the day.

However, I love shooting between 24 and 50, and I want the low light and compositional advantages of a really bright aperture in that range. It'd be great for astrophotography.

How would you compare the IQ of this lens to that of the Sony 24-50mm F2.8? I recognize the advantage of the Sigma’s maximum aperture, but the Sony has a better zoom range and is half of the size and weight of the Sigma. Could the Sony replace 3 good primes, from the perspective of IQ? Thank you.

[@jeroenvdw]

I don't think the Sony 24-50 2.8 can replace 3 good primes... A good F/1.4 or F/1.8 gives much better out of focus areas and you can lower your ISO a lot to get cleaner images.

[@warrenbarnes9653]

@@jeroenvdw In order to minimize size and weight, I am referring to the newer series of primes with an F2.5 - 2.8 maximum aperture. The reviews suggest that the Sony 24-50 has image quality that equals or comes close to many primes, especially the newer, compact variety. So I wonder how this compares to the new Sigma 28-45, i.e. whether the Sigma is even better. A two pound Sigma zoom lens with a narrow range is inconsistent with my personal objective concerning size and weight, whereas the Sony lens serves that objective, as long as the IQ is excellent.

@@TechnoBabble Not saying f1.8 is not important, just saying it is overrated if you have to step the lens down to get great results. If sharpness is not important to you, then that is fine. To me, I see sharpness issue coming up much more than lateral and longitudinal aberration.

[@TechnoBabble]

@@BorisZX6R If you think this lens needs to be stopped down to get great results then there's no hope for you. It's very sharp wide open, sharper than anyone but the top fashion or product photographers in the world would need. You're nitpicking the sharpness in the far corners compared to a lens you likely already own so that you can justify your own purchase. I own a Sigma 40mm f/1.4, I can basically guarantee it's sharper wide open than any lens you own. And yet I can still see that the 28-45 is a sharp lens and can think of many use cases for it, imagine that.

[@vicronychen]

a jaw dropping prime zoom lens.

[@hedydd2]

While I’m sure it is an excellent lens, the large size for a sub 2x zoom at that price means I’ll give it a miss given that I have a 45mm f1.8 already. Others may love its high quality of course.

[@johnstark8116]

Please Chris, test some 70-200 f2.8 😊

[@hendrickziegler8487]

I am pretty sure that he has tested most of those that were released in the last 10 or so years. Just type "frost [model name of lens]" in the KZbin search bar

[@JaySilva88]

Sigma is clearly not the same company from 20 years ago producing cheap lenses. This lens is razor sharp and produces perfect images, for a reasonable price.

[@johngreenwood9247]

Incredible performance ...but wait a moment, wouldn't a 35mm f/1.4 GM (or even fe 35mm f/1.8) lens be lighter, cheaper & offer better performance, over 90% of general photographic situations? Yes, I'm sure videographers would find it a great proposition, but I'm always surprised how, by moving back a few feet I can avoid the need for a 28mm prime over a 35mm one. Now a "true" 24mm focal length @ the short end & possibly 50mm @ the long end would be a greater attraction. I just think this optic offers an answer to a question that not that many people want to know. Very clever & interesting as it may be!

[@sottheaphoeurng9044]

I wish it would do 20m-50mm even f2 is fine or 35mm-75mm is fine too

[@joerg_koeln]

Hm, I don't see the advantage of such a zoom range. However, the optics is very fine.

[@gregsullivan7408]

Bugger! Bought the Sigma 50mm F1.4 just YESTERDAY, before learning about this one - i would have got this instead! 🤣

[@DirectorKalou]

NICE

[@cy9nvs]

It's cool and all, but personally, I couldn't think of anything I'd need a 28-45 lens for. Really is a pretty small zoom range.

[@TechnoBabble]

The 18-35mm f/1.8 that tons of people used was equivalent to a full frame 27-52.5mm, not much of a difference.

[@davidpossien3061]

@@TechnoBabble 18-35 can be used on full frame at 25mm using a hack. 25-52mm is quite a large range for such a fast lens. I'll personally be sticking with my 18-35 for video. This new sigma really only makes sense for photography.

[@TechnoBabble]

@@davidpossien3061 Where are you getting 25-52? It's 25-35 on full frame, you don't just magically also get the APS-C crop equivalent.

[@davidpossien3061]

@@TechnoBabble I'm glad you asked. Assuming you're shooting in 4k, in full frame mode, you get 25-35mm (the part of the zoom range without a vignette). In APSC mode you get 27-52mm equivalent (assuming a 1.5 crop factor). Add the two together, and you get 25-52mm. So using the full frame mode, it really only gives you an extra 2 mm of usable range...however the cool part is when using the e-stab on high on full frame mode, it gives you all the benefits of a full frame lens using the entire lens' zoom range. This of course works on the apsc mode as well, but that's not newsworthy. The newsworthy bit is that you maintain more field of view using the 18-35mm in full frame mode with e-stab. I've tried it. It works well, and it's free...since I already own it. Perhaps I should make a video to explain. Now, given what I've outlined above, and this new Sigma lens...which one do you think gives a wider field of view, assuming that is more desired?

[@TechnoBabble]

@@davidpossien3061 well I never said anything about which one gives a wider field of view, nor did I or anyone else in this thread say anything about which is more desired. Using your same logic the new lens gives you a more telephoto field of view, so it's better if that's what's desired. Oh, and you're also making the assumption that the APS-C crop video on the camera being used is good quality or even still 4k, what about the A7S III/FX3/FX6? Also, it's free cause you already own it? Clearly your entire argument is from the point of view of someone that owns and is happy with the 18-35, nobody said you should upgrade. You're clearly just trying to defend your existing gear against... Nothing? Plenty of people don't own the 18-35 because they shoot primarily on full frame and a 24-70 f/2.8 makes more sense, so this is a cool lens for both photo and video.

[@geoffreybassett6741]

@3:45 I have to say I greatly disagree. I would want this lens for interview work and that breathing is bad enough to be noticeable I believe.

[@bikash3003]

How are you Christ?? Love❤❤ you from India ❤❤

[@jtoyp]

The lens seems solid but my wrist not enough

[@aldrindetablan4358]

this is the ff 18-35 1.8

[@hazard3020]

Whats the point ? Tamron already have a great 20-40mm and a 35-150mm. Sony have a great 24-70 2.8 / 24-50 2.8 / 16-35mm 12-24mm and excellent 24-105 f4 too 🤷🏼
