Sigma 28-70mm f/2.8 DG DN 'C' lens review with samples

For what it's worth, front elements are so strong that any impact that could damage one outside of what'll cause the tiny scratches that unnecessarily hurt resale value would almost certainly destroy the internals even if the front element survives. That said, if it's really dusty or really wet where you live, then it might do you some good if your lens doesn't have the kind of coatings this one does.

Pointless release for Sigma this. The mirrorless 70-200 and 150-600 would have been so much more successful than releasing a lens that has so much competition already.

When I was young and shooting film, a 28-70mm f2.8 was often a part of the standard photog’s kit which included a fast fifty, a 70-200 f2.8, and a 17-35 f2.8 or f3.5 if you were a Minolta shooter. I think Canon made the 24-70 f2.8 popular as a standard pro zoom, but I could be wrong. I used a 28-70 for the longest time. Happy to see Sigma joining the ranks.

Did you mean to say the Tamron is a bit sharper?

It is not a very impressive lens but good if you consider what it delivers for such small and light package. Having said that i really do wonder for who this lens is marketed. I think most professionals want the flexibility to go wider. Enthousiast are better off with DSLR in terms of quality/price. And it is yet too expensive and overkill for the typical consumer.

Dear Sigma, most of us need 24 mm, thank you (?

It's good when companies releasing new lenses but I want a cheaper 16-35mm f/2.8! I'm talking to you sigma!

i really think you may have a bad copy of this lens.. Because at the 70mm end it should be sharper than what you have

For those of you asking why sigma can't release an RF version, ask why Canon does not give access of their protocols to any 3rd party makers. Enough with your complaints. Switch to sony. Nobody forced you to buy a canon camera.

Why the heck did this get made when Tamron's exists and Sigma's 24-70 exists?!

Why couldn’t they just kept at 24mm? And make it as a Mark II version. The size and build is desirable being small/compact.

Almost quiet so.... louder than Sony 16-50 F3.5-5.6 OSS?

Do I want this, or just find something I like in the i Series?

Great reviews. I really love this channel. Good job Christopher!

I think I like this lens. It’s not perfect but neither am I.

You don’t seem to be compensating for any field curvature in the sharpness tests, though. May I ask why not?

Need your opinion on the new Tamron 17-70 for apsc. Thank you!

I really hope this lowers the tamrons price

28... Eehhh, why 28? Mediocre angle

Would like to see a review and comparison on the A7c against the 28-60mm kit lens and 24-70mm f4. Is it worth upgrading to the Sigma if you own either of these Sony zooms for example.

I like that quick and subtle “L- Mount alliance“ reference lol

Great review. Would love to see a comparison with the Tamron. None on YT so far.

This is a cute lens

They say dust resistant, but I wonder if it still sucks in dust like a vacuum like the Art version does.

These lenses should cost no more than $500. It's not worth it. Get the 24-70mm f2.8 for $200 more.

Thank you. Would you make a comparison test of this lens vs the Sony FE 28mm-70mm? Dig for situations where they differ. There are thousands of people who have the kit lens and are looking for a nice upgrade. One very intresting comparison would be at the Sony's sweet spot of 35mm f4.0. What trade off do you get when shooting 35mm f2.8 on the Sigma at half the ISO? Sharper and less grainy colors? Does the 2.8 auto fucus faster than the 4.0? Then how do the two lenses compare when the Sigma is set at f4.0?

Going on my A7c as soon as it’s available!

that distortion is serious at both ends

Too much hope on software corrections.

This lens is a winner.

So, in short, a limited range which is soft all over, has loads of distortion and suffers from above average vignetting.
And looks best at f11 🤣🤣🤣

Great review except for the AF test done on the same old A7rii.

Mostly shoot primes, but very attracted to this lens for APS-C in lieu of the 18-56mm due to the brightness for the size. The i-65mm first, though.

what UV filter you recommend ?

I was hoping they would release this for EF-M mount as well but seems unlikely at this point :( Chatting with some guys at B&H, they told me the 3 Sigma primes for the EF-M has been some of the best selling lenses they carry in the entire store, so I really hope Sigma takes the hint.

I would really like to see your review on Sony FE 28-60mm

I have got this lens and I have rather mixed feelings. It is very light and compact and this was the main reason I've bought it but video autofocus is definately not on par with the sony lenses. I have tried it with sony a7siii and a7iii and especially on a7siii continuos af in video behaves quite strange- pretty good when there is a face in the frame but terrible when there are only still objects. In this case it usually "forgets" to acquire focus properly when changing composition, moving frame ets. It is just stuck and I have either to use an af button or change af area from wide to center or zooom in and out a bit to get it to work. It is quite annoying. Every sony branded lens I have (35mm, 85mm, zeiss 16-35, 24-105, 20mm) work flawlessly and move focus seemlessly. Funny thing, with the a7iii the problem is less visible. Af in stills on both cameras works very good.

can you please review the Tamron 17+70mm f/2.8 for APS-C cameras ?

Despite being an informative review, I mostly enjoy the pictures presented here. Some are just beautiful. Well done !!!

Hi, I've been subscribed to your channel for a long time and congratulations on the always very technical reviews. I own a Sony A7R IIIA and would like to get the sigma 28-70mm f / 2.8 dg dn c. Not being an ART series, the lens is able to "resolve" the 42 mpx sensor in terms of sharpness and detail? Thanks.

Please compare this lens to the new G2 version of Tamron 28-75mm f/2.8. Should be quite a shootout!

Great review, just bought this Sigma 28-70. It is on sale and included a free B+W filter, a deal I couldn’t resist. Based all the reviews I saw, Sigma 24-70 is a better lens and that 4mm difference in wide angle is large. However, I love the small size and light weight of this lens, should go well on an A7C. In reality, unless I do side by side pixel comparison, all these lenses are great. I rarely use zoom, but this is a versatile lens to travel with.

Genial review. Me ha servido de gran ayuda.
Gracias!!!

I hope sigma can make a small 24-105 or even 24-70 f4 that’s light for travel. Also super excited about the rumored sigma 14-30f4 !

What do you choose sigma 28 70 or samyang 24 70 f2.8 ? Thx

great review sir cris. how 'bout using a5100 camera for this lens, is it ok to be replace my kit lens in a5100?.

Can you control zoom via buttons from the camera as you do on sony lenses? I have never had a Sigma zoom lens yet.

You have very nice photos. Do you edit them in lightroom?

Would you recommend this lens on a6600?

This lens doesn’t feel cheap it’s the lightest and best price lens ever ! Love it 😍

This lens is in my top 3 👍🏻
