I think worth to mention the tamron is fully weather sealed not like the Sigma 28-70.

Just because Tamron markets their sealing more doesn't mean it is better.

[@R2StudioMasterclass]

very on point and much-needed video, thanks for the info, one more thing I think it's important to mention the Weights as well as many people using these lenses over the Sony G Master lens for video use as its less heavy and easy to use. Specially when using with a Gimbal. Sigma 28-70 16.6 oz / 470 g Tamron 28-75 1.21 lb / 550 g Sigma 24-70 1.84 lb / 835 g

Great video as always Christ. I love this tri-comparison format! Would have loved to have seen focus breathing comparisons too since that is really important for video!

[@mrdmahesh]

Great comparison Chris as usual. Clear n concise!!

[@nikkipedro]

Another great video, thank you Christopher. A little late for me however as I have had the Tamron since the first release almost 2 years ago now. It has been bashed and crashed and is still going well. I like it so much I just bought its bigger brother, the 70-180mm. I hope it is as robust as the original. Thanks again.

[@artmaltman]

Superb comparison. Very clear and demonstrates the most salient points for most people.

[@dalefrolander3583]

Great comparison video. Now that there's a new Tamron 28-75 G2, I hope you can compare them again, but with the new G2 lens.

[@mjcatto]

A huge thank you Mr. Frost. Waiting on pins and needles for a review like this. Need a good zoom for my SL2. 24-70mm gets the nod! Cheers

[@richardpcrowe]

Well done, as are all of your reviews. The results are exactly what I suspected... Although the Sigma 28-75mm has a very slight edge over the Tamron, the difference will not cause me to switch form the Tamron, with which I have been shooting for several years now! I have been very happy with the 28-75mm on both full frame and APSC format cameras...

[@aboukhairi2086]

hi super reviews you're performing, i'm following your job since some years..... i personaly prefer struggling with fixed lens focals and move my feet rather than acquiring expensive zoom lens. I love your way of evaluating lenses.Please keep doing your fantastic job on line...Thanx

[@MollyFitzBrown]

I'm looking for something as light as possible, do you think the Sigma 28-70 would still edge out the new Tamron G2?

[@CarlBergsdorf]

Thank you Christopher, very informative video. I recently bought an A7III and am thinking about either the 28-70 or 24-70.

[@christianboehm6100]

When you tested the Sigma 24-70, did you account for its strong field curvature when testing the corner sharpness? I found that the corners are much sharper when you focus on them as opposed to the center of the frame. It's a little annoying when you have an element closer to the lens (adds an extra step to focus stacking), but not too bad at the end of the day.

[@twagn]

I prefer 24mm on the wide end as well. The Sigma 24-70 is on my shopping list

Thank u so much... This is very informative.

[@warrenbinder3612]

Glad to know that my 24-70 f2.8 that I bought used/like-new for $900 is still a good deal :)

[@thegeneral123]

Sigma 24-70 F2.8 owner here, one thing worth noting is that the Sigma 28-70 is not weather sealed. It has a rubber o ring at the mount only. So it's unlikely to let water into your camera but the lens won't hold up so well.

[@dmitrylitvinov7328]

Thank you for pointing out that, deal breaker for me as weather sealing must have in country I leave.

[@ALWH1314]

Thank you for the review as usual. Just purchased a Sigma 28-70 for its light weight and small size even though 24-70 is definitely a better performer. The lens was on sale so it was cheaper than Tamron 28-75. Hope I won’t regret.

[@lewcehjitl3282]

Any updates?

Thanks! I'm not sure you have any L-mount cameras? If not you should try a second hand Panasonic S5, because then you can try out the Panasonic 24-70 S- Pro 2.8, it really a stunning lens, as are all the little 1.8 Panasonic primes, I think you'd enjoy them all.

[@UkuleleCreations]

Thank you! Very informative

[@Pajflowerful]

Thank you!! Love it!

[@louisliu5440]

Thank you Chris. Useful comparison. For portrait photography I will choose the sigma 28-70 due to the lighter weight and smooth bokeh.

[@martin9410]

I have had all three lenses. The lens I have now is the Tamron G2. I find the AF and contrast must better on it than the Sigma 24-70 lens I had. So had to send the Sigma back and keep the Tamron.

[@lorenzogattaldo3764]

Thank you, this is very useful.

[@summonedfist]

While my personal copy of the 2470 hasn't had dust issues (yet), I've read a fair amount of complaints on the tamron too. And since dust doesn't typically affect image quality until a LOT accumulates, I chose the 2470 over the tamron due to it being wider and nicer bokeh.

[@probolehla]

got mine for one month.. already got 2 small dust underneath the first layer of glass :’)

[@summonedfist]

@@probolehla that sucks to hear. I started using mine tons lately and it only has a couple of more specks inside. Here (GTA, southern Ontario) there's a place we can drop it off at to have it cleaned/resealed for free under the warranty. Hopefully you have something too?

[@lgndrystudios9008]

Love the vids bro

[@zenza7120]

I came here to see if new sigma has advantages in addition to size and weight over sigma 24-70 Art. As an enthusiast, I am a bit struggling with the weight of 24-70 art lens, but I'll keep considering its optic quality and more importantly due to its wider focal length.

[@kifley19]

I like the Sigma 28-70mm 2.8 because of the size. However, it's kind of soft at 70mm and I'm afraid of dust. I will wait will until people confirm if dust is an issue long term. Also, hoping price drops as well.

[@DennisMoncla]

Exactly the video I was looking for Chris. Thanks. Are you planning on doing a Sony Vs Samyang 35 1.4 comparison? I bought the Samyang after watching your video and I do love it. Some of the best bokeh I've seen! I've even thought about getting their 85 because of it and selling my Sony G 85.

[@haydar9004]

At this point, lets agree to wait sigma series for every sony lens

[@pawelmod3292]

Does anyone know how Sony 24-105G F4 is comparing to these lenses from sharpness and "micro contrast" perspective? (the OSS, smaller aperture and wider focal length range is an obvious difference of course)

[@JB_Hobbies]

I’m pretty sure that people who take their photography very seriously get these lenses, too. They are not just an intermediate step. They simply are budget-ish options. And, keep in mind, the Sigma lenses are first party on L-Mount.

[@smodjo]

Very nice review. For me the new SIgma 28-70 is the winner because of its size and nice bokeh. I will consider this one. Thanks a lot.

[@stefpix]

Great review as always, to the point. I just wish you had shown the same bokeh shot of that teacandle on the shelf for all 3 lenses. Many report that the Sigma 24-70mm sucks in a lot of dust. 220 USD extra for the Sigma 24-70, may not really be worth saving to get only 28mm widest and poor close up performance. I think the 28-70 would be more appealing at around 700 USD, maybe 750. Anyway, all these lenses are more than good enough, you can take great photos with any if you have talent. the small 28-70/75 may be nice for event photography. Maybe the Tamron 28-200 is a better buy after all than the 28-70.

[@katasiapa]

Nice review.

[@ztanizlaf]

[@u.d.7543]

I would like to see a comparison of similar lenses for sony apsc.

[@djiflyer7577]

@christopher No problem with dust in the Sigma lenses? That’s why i bought the Tamron.

[@TheRealHarrypm]

it should be noted that the 24-70 DG DN Art is 800GBP on E-infinity etc

[@lewkon]

You missed one important detail: Tamron is weather sealed, and Sigma 28-70 is not.

[@choti001]

Hmm I got 24-70 Art for $899 on Black Friday. Yes, it's heavy but for its price, it has been fantastic. I really liked Sigma 18-35 design that zooms and focuses internally.

[@ahmonon4352]

Sigma 24-70 is really tempting, I wish for a similarly priced and performed sigma 16-35 f/2.8 for Sony. Sigma 14-24 is great, but I'm a circular filter guy 🙁

[@unickolay]

Hello! Thank you for your review! Let me ask you two questions: 1. I heard that the previous sigma 24-70/2.8 lens had dust problems. Users said that it sucked a lot of dust. Is there the same problem on the new sigma 28-70/2.8? 2. Will autofocus work slower when shooting videos and photos than on the native Panasonic 24-70/2.8?

[@elchinoxl3034]

They made an updated version of the sigma 24-70, after the serial number

[@JoaoRodrigues_photo]

Can you make a comparison between nikon, and canon mirrorless 50mm f1.2?

[@TaanielMalleus]

If you use filters, bear in mind that the 24-70 has an enormous 82mm filter thread.

[@PASquared]

82mm has become the new norm these days for pro zooms, whereas the norm used to be 77mm

[@tkermi]

@@PASquared Yeah, for all kinds of longer telephoto use as well as fastest short telephotos 95mm is very common also. So I would say that only 105mm and especially larger than that are not so common (105mm is still quite cheap and easily available).

[@YakAlmighty]

@@PASquared eh pretty much all my sony lenses use 67mm thread (Tamron 17-28, Tamron 28-75, Tamron 70-180, Sigma 35 1.4, Sony 85 1.8)

[@PASquared]

@@YakAlmighty I guess I should have said Pro OEM/Camera brand zooms.

[@mirrorlessny]

@Yak Almighty I'm trying to have all lenses with 67mm too = easy to swap magnetic ND filters, probably will never happen 😦 some nice lenses out there that are not 67mm

[@mikey7326]

[@mohamadavakian]

really thanks for comparison 👌 definitely sigma 24-70 is the best choice

[@hpud1876]

great comparison

[@GaryJahman]

Thanks for the comparison! Wanted to make one myself. I have one huge negative with the Sigma 24-70 and that is the dust collection within the lens it self. With the Tamron I did not experience this. The smaller sigma 28-70 is a nice alternative if compared directly with the Tamron. Although I might miss the 75mm reach. Also nice to mention that the Tamron lenses all have the same filter thread 67mm if not mistaken. Eiher way you cannot go "wrong" with one of them. Really curious to see if sigma is also going to make a light wide angle zoom or telezoom lens

[@amitkrupal1234]

I have observed dust in back of this sigma 28-70 in this video.

[@NickL0VIN]

I wonder if the new sigma 28-70 will easily collect dust too. I mean, same concept design as the 24-70, and much less weather gaskets inside. Sounds like a dust disaster waiting to happen!

[@Tzadeck]

I really don't understand why people talk about having dust in their lens--I've never seen it have any effect on image quality whatsoever. I guess theoretically if you're at f16 or something the contrast could suffer where the dust is? Not even sure that's true.

[@NickL0VIN]

@@Tzadeck if dust gets in it easy, moisture gets it in it easy and i've had fungus before in lenses (that had dust in it)

[@Tzadeck]

There's no evidence that a lens being weather sealed makes it more or less likely to get moldy. Moisture and mold spores can get in any lens. Even if you assumed that it's harder for moisture and spores to get in lenses that are better sealed, it also means that it's harder to ventilate the lens and for moisture to get out once it gets in. If you have expensive lenses, you should make sure they are stored in a dry environment and they get sunlight regularly. That's the real solution to this problem. You can buy a dry box on Amazon for 100 USD or so.

[@SteenWinther]

I would have loved to see the Sony 24-105 in this lineup because it is generally less expensive here in Australia than the Sigma 24-70!

[@prateekpujara5742]

Is it 2.8?

[@KGi4]

Hi Cristopher, could you do review of Tamron 35-150mm? I own Tamron 17-35mm and 35-150 would be very useful, but i am not sure about its quality. Thank you in advance :) Your reviews are very useful

[@holgerschmitt2392]

Thank you for this good comparison video - help me to buy the right lens :-)

[@tomtomtom7411]

I agree with your conclusion

[@khagesh7530]

how come that the image quality becomes so soft at close focus distance at 70mm? at normal distances the image quality is noticeably better at 70mm. Is there any explanation for this?

[@sharikmarius]

If not for the busy bokeh, I'd go with the Tamron (I have the 17-70 for my a6xxx series camera). As it stands, I'm undecided. I'll have to view more Tamron images to see if the bokeh is decent enough or not.

[@Flo-con]

Thank you very much for the comparison. So the bokeh of the Sigma 28-75 is somewhat better than the Sigma 24-70? This is the one thing that bothers me a little with the latter as I've heard the bokeh is subpar. There was also the concern with dust incursion but according to a Sigma rep I emailed today, they're made fixes to improve it in that regard.

[@christopherfrost3650]

I found the Sigma 28-70 to have very slightly smoother bokeh than the 24-70, but my tests were hardly exhaustive - they're both excellent in that regard

[@trumannnnn]

And af in video? Which is better?

[@sussar]

I use A7Riv, for travel photography, Sigma 28-70 is 80 grams less than the Tamron, with just additional 150 grams, I can bring the laowa 14mm F4 as well, it's excellent combo for travel. Just do some post corpping I can say this combo enough for almost all scenario.

[@Xetenor]

I really love my sigma 24-70 2.8 dg dn lens. It's seriously amazing for landscapes and even did better than the sony 24-70 gm that I tested it against shooting the same scenes at the same time. My first 24-70 and It's amazing.

[@DavidChiriboga]

How have you felt about the size and weight for casual usage and carrying around? That’s my only concern as a first time pro lens buyer.

[@jbello9398]

true it's a bit heavy but no lens is perfect. I just got the lens today, feels like a beast. I read some people complain about dust getting inside the glass, but it shouldn't be an issue with the images... hopefully

[@Tzadeck]

@@jbello9398 Ah, don't worry about the dust. Dust in the lens never has any effect on image quality whatsoever. I've even heard the head of a large lens rental company say that they have to clean out dust from their rental lenses every once in a while--not because it has an effect on image quality, but because some people THINK it does. Also, a lens getting dust in it isn't necessarily related to how well it keeps water and moisture out, or its likelihood to get moldy, which are real problems. Plus, I've owned the Sigma for about a year now and mine really doesn't have noticeable dust in it yet.

[@nightcoder5k]

With that focal length range, it's the only lens you need for most of the time.

[@nosensenononsense]

I would be really interessted to see how the real BUDGET option, the litte Sony 28-60 kit lens, would compare here. It has recieved a lot of praise for its optics and still everyone complains about the price. Guess build quality sucks real bad ;)

[@doros9.2]

Sigma, please release your DN lenses for the Canon RF mount. Thanks!

[@JavisandLea]

Great review! Picked up the 24-70 a while back and some thoughts: -It's the heaviest of the bunch and it matters especially if you're using it for an extended period -Can confirm that dust does build up behind the front element Given the 28-75's poor bokeh performance I'd go for the 28-70 and pair it with a wide angle prime

I have the Sigma 28-70, I love its lightness and overall image quality. Though I find myself often maxing out on zoom, exactly where the lens is weakest. When I shoot f2.8 at 70mm the area just out of focus often looks noisy...almost like motion blur...it annoys me to the point I wish I had gone with the 24-70 ART. Or, perhaps I need something with more zoom since Im maxing it out all the time.
