[@john_in_Berlin]

Yep, this lens rocks. I use it on my Sony a7c and have zero complaints. Images are just delish, extremely sharp, excellent bokeh. It's slowly becoming my EDC. Thanks for another efficient, pragmatic, checking-all-boxes review with your signature soundtrack. 🎉

[@stevenwaldstein2249]

Thank you as always for your excellent review. I’ve decided to give this a try and bought a nicely priced used one to pair with the A7C in a small kit. If and when I think I need wide I can use it along side my FE 20/1.8 or Loxia 21/2.8 and still have a kit lighter than my FE 24-70mm f/2.8 GM on my larger 4th gen bodies like the A1 and A7R IV.

[@jayclip80]

Thank you sooo much for this video. I'm thinking about getting this lens when it drop

[@GregThurtle]

nice to see steven seagull again :) nice review Gordon - looks a nice viable alternative to the tamron as a travel fast zoom. Sony E mount has a huge lens selection now, lets hope it makes it's way to nikon Z and canon RF to give those owners good alternatives too which would only be good for the industry as a whole!

[@andrear9500]

On a single lens choice I’d prefer having 24mm. Above all I would choose quality over range and size when it comes to 2.8 zoom. I am a bit surprised with regard to vignetting and soft corners. Curious to see comparison with Tamron. Thanks

[@paololarocca7684]

thanks for the review, excellent compact zoom! As a general purpose zoom/travel/landscape zoom I prefer a 24-70 f4 but for low light situations like events this is a great option....

[@cliffordgoh4278]

Thanks for the review! Using the a7c, it is a great system with this lens, however I noticed the same issue you have noted - where the Eye AF @ f2.8 misses the eyes exactly, on a rough 50% of my shots. (A little more often on the longer end than wider) I hope Sony's able to fine tune this issue through a firmware update as the lens is perfectly weighted and encourages me to bring it out on my a7c alot more often!

[@mbvglider]

This lens has very pleasing image quality and the size is closer a Micro Four Thirds f/2.8 zoom than a typical full-frame f/2.8, even f/4, zoom. I'm finding myself using it in casual situations where I might have used a prime or a kit zoom before. I understand that this is probably not the best standard zoom for professional use, but these days, you could easily justify replacing a f/2.8 trio with something like a 16-35mm f/2.8 + 35-150mm f/2-2.8 duo, so the standard zoom is not even necessary for professional use, so we could easily consider a more casual alternative.

[@jockslifeatliftvideoproduc8528]

100% agree! Been trying to justify this lens to myself as a B-cam lens just so I can buy it for my general walk around lens rather than my Sigma 24-70mm f2.8...

[@marknathan7744]

I have this lens and this review is a fare assessment of it. I will probably in the future go for a 17-28 if sigma make one for l mount . I actually prefer just using compact 35 and 50mm f1.8 primes in this focal range and will probably sell this zoom once more l mount lenses become available great review as always.

[@MollyFitzBrown]

Do you think this would be a good choice over the new Tamron G2? I like that it's not as heavy!

[@cameralabs]

Not sure as I've not tested the new Tamron myself, but my friend tests a lot of lenses on my website at cameralabs.com which you may find useful.

[@kifley19]

I'm worried about dust getting into the lens. I don't get why they cheap out on that. The 24-70mm 2.8 has an issue with dust as well.

[@JacopoDiGiuli]

Great review... thanks as always!

[@cameralabs]

[@Alexrocks1253]

I wish it was fully weather sealed like the Tamron version of this lens. Would’ve made for a good pairing for my S5 like my A7RIV and the 28-75! I do go in full rain often so sadly it seems this won’t do for me :(

[@bebedaily]

Thanks 🙏🏼

[@WeTheKims]

do you think it's too heavy to be on my camera all day during travel? I dunno whether to go for sony 28-60mm kit lens for the lightness or this sigma 28-70mm for the bokeh... (i shoot mostly video)

[@cameralabs]

It's twice the weight but I'd,say still light and worth it

[@WeTheKims]

@@cameralabs Thanks!

[@MyNameIsPetch]

I think the price difference between this and Sigma's 24-70mm is almost insignificant, the real reason to get this lens is the size/weight

[@user-hr9zm1em9o]

评测非常中肯，很小巧的入门级变焦，旅行的话24-105或许才是最佳选择。

[@charruaporelmundo]

I hope sigma will also compete agains the 28-200 from tamron.

[@stefpix]

The Tamron maybe is a better overall value. Sigma looks sexier but it may be a dust pump. 28-70 2.8 is great for events and lifestyle, but it is nice to have 24 mm. Although now Lightroom is great at stitching photos that the need for ultra wides and wides is less stringent. But price should be below the Tamron to be competitive. The Tamron hopefully will lower in price because of this.

[@mahektailor4542]

It's a no no I miss 24 mm in Tamron so much that I regret some time

[@standfest_party]

Thanks for reviews. Waiting for comparison with Tamron!

[@zhuoranhan3518]

I like its size and weight much more over 24mm. In fact, personally I like 28mm more than 24mm.

[@NickL0VIN]

I hope it doesn’t collect too much dust. I’m gonna get it due to size

[@paulbeckmann]

Great review as always!

[@cameralabs]

Thanks!

[@andreasschaefer8613]

24mm would be nice, but heavy and big Zooms were not my cup of tea anymore. I've owned the tamron 28-75, but also that was too big for me, the sigma might be the right choice, testet it in a shop and found the size of it very nice! Now I have to decide, if I want to buy it or use my 35 primes instead and my feet for zooming.

[@colingregg]

Can you do a review comparing it with the Lumix 24-105 f4? This is the one I use with the Sigma fp but am very tempted by a lighter lens. What are your thoughts.Thanks

[@cameralabs]

It would be interesting but I fear it would have very limited appeal as a video, so wouldn't justify the work that would go into it. Each of my videos takes 1-2 weeks to test, film and edit, so they need to provide 1-2 week's worth of income as this is my only job. So I have to be mindful about the reviews I undertake.

[@matzzeglaeser]

Thanks. That was the most comprehensive review of the lens for me.

[@cameralabs]

You're welcome!

[@lunalu9117]

looks great, i judt dropped a solid bit on a Z5 and it's 24-50 kit, think the 28-70 sigma would compliment it?

[@cameralabs]

It'd be perfect - if they made it in Z mount!

[@stefpix]

I also bought a Nikon z5, after 5 years shooting with Sony (kept my Sony apse cameras with 16-55 and sigma primes). You can find the Nikon 24-70 f4 refurbished or used like new for half price and it is really good. 28-70 2.8 is great for events and lifestyle, but it is nice to have 24 mm. Although now Lightroom is great at stitching photos that the need for ultra wides and wides is less stringent

[@CharlieVN]

Great review, 4mm makes a huge difference, I can add the 17-28 with little weight penalty compared to the 24-70 art

[@cameralabs]

Exactly, my point was while it's nice to have 24 in a general zoom it may be nicer still to have it as part of an even wider zoom.

[@9988RedefinedD]

Does it changes focus when zooming

[@JamesClark1991]

Is this lens Parfocal?

[@twentyfifthjt7888]

Would have been preferred even 24-60 mm over 28-whatever... but hey. Also, first... on to the review.

[@cameralabs]

I think that a 24-60 would be bigger and pricier than a 28-70, but I agree, the range would be lovely. Like that Lumix 20-60 is a perfect range BUT the compromise is the dimmer aperture.

[@kifley19]

24-65mm 2.8

[@twentyfifthjt7888]

@@kifley19 I like that range.. but 5mm less at the telephoto end isn't going to make it much smaller.. If quality was the only factor the original was already great, but if they just wanted to beat Tamron at size they could have gone 24-60mm or 24-55mm to have leeway to make it small.. & peoole get to choose whether thry want the wide end or the low end of the standard zoom.

[@RensKapoor]

Confused between tamron 28-75 g2 and this one… does it get soft after 50mm especially at 70mm? A lot of reviews say that.

Enjoyed this video Gordon because I'm a big fan of Sigma lenses I started using them back in the early 80s on my Minolta xd11 camera and I still use them to this day I currently have one on my Canon T2i I believe it is a 28 - 300 mm lens it takes wonderful images. I can live with its little quirks. I believe they're good quality for the money. How about Tamron lenses I use them also Gordon.. take care Gordon be safe.

[@cameralabs]

[@dch2896]

These lenses will suck in dust like no tomorrow. I like the size but these lenses won't last long until you have to send it in and get it cleaned.

[@onchky]

Got it for a month already, zero dust. And I bought it used as well.

[@Michaelpai1230]

Anyone know how many FPS this does on electronic shutter for the A9? (Granted most of us will shoot it on single shot for travel)

[@cameralabs]

I've not tried this exact lens for e bursts BUT other Sigma DG DN lenses fired at a max of 16fps on the A1. Not sure about the A9.,

[@Jgheiler]

Would you think this lens on an a7iii would outperform the sony G 16-55mm f2.8 on an apsc?

[@cameralabs]

That's the big question, and without comparing them side-by-side, I can't say, sorry.

[@elmachomen]

Great video, as always Gordon! Another great lens from Sigma... today, we're really spoiled for choice. I have a question though, when you take the shots to analyze the sharpness at the closest distance, do you take into account field curvature? The distance to the sensor from the plane of focus (or the element in which you choose to focus) is different at the center than at the extreme sides of the field of view, so when shooting wide open and so close, if the lens is not corrected for this, the plane of focus (being so thin in this conditions) will curve leaving the extreme sides of the image, that are following a flat surface in this case, out of focus. To test edge sharpness I always focus on the edge, otherwise field-curvature needs to be taken into account. The lens might be sharp in the edges but if the lens is not corrected for field-curvature, it won't matter when shooting because the plane of focus will curve leaving subjects that are in the same plane as those in the center of the frame, out of focus. Anyway, sorry for the rant, just wanted to know a little bit more about your process when you film these amazing reviews. Keep up the good work, greetings from Edinburgh!

[@cameralabs]

there's two ways to test and ideally you'd do both. One focuses in the middle so will reveal field curvature and the other is where you measure edge / corner sharpness by actually placing the focus area there. I tend to do the former, but in the written reviews at cameralabs.com myself or Thomas sometimes do the other. This particular lens was focused in the middle.

[@dalziel7864]

I bought the Sigma 28-70 for the L mount and and i am dissapointed, dark corners, focus breathing, so much hunting in low light, it's inferior to the Panasonic 20-60 that my Panasonic S5 came with. Could be a problem with software integration betwen the lens and the camera, but until it's resolved, this lens will continue to disappoint

Sounds like a firmware update is required to perform the required lens corrections. Dark corners are normal on brighter lenses though at their maximum apertures.

I'll be frank, I really don't get the point of this lens, I own the Tamron equivalent which mentioned is in the same ballpark for price weight and size but with slightly better advertised sealing. The AF/MF switch seems to be the only physical difference. I guess I'm price insensitive but the extra 200-300 dollars/pounds for the 24-70 seems like a good value if you ask me.
