Any comparisons between the Sigma 16-28 and Panasonic 16-35 for L mount?

I've ordered the Sigma 16-28 which means I'll shortly have on my hands the Sigma, the Tamron 17-28, and the Sony 16-35/4 OSS. As a bokeh fetishist I hope to do my usual bokeh comparison. Any other requests?

Right, here comes a quick comparison/measurbation of the Sigma 16-28 vs Tamron 17-28. YouTube has plenty of excellent comparisons of landscapes and test charts, so I bring you environmental portraits with bokeh, which is what I like shooting most of the time. Apologies for the banal subject matter - putting the kids in the sandpit is the only way I could get them to sit (reasonably) still.

TLDR: Both lenses are really close, neither is "better" than the other; the Sigma appears to be optimised for <=20mm whilst the Tamron is uniformly strong throughout the FL range. Get what you can get your hands on or afford; get the Sigma if the extra 1mm wide angle matters.

Here is the album with crops and full-size samples of the comparison. All shots from A7R III, RAW files processed using Capture One 12 with low sharpening.

16/17mm @ F/2.8 - Sigma top, Tamron bottom
A strong performance from both lenses with fairly inoffensive bokeh on both. I'd give a slight edge to the Sigma for sharpness and contrast, but we're literally splitting hairs here. The 1mm FL advantage on the Sigma is real and potentially very handy.

20mm @ F/2.8 - Tamron top, Sigma bottom
I'd give a very slight edge to the Sigma here, see the marginally sharper straw hat with marginally less CA. Sigma has "messier" bokeh but personally I prefer it to the high-contrast and overly structured bokeh on the Tamron.

24mm @ F/2.8, Sigma top, Tamron bottom
This FL appears to be Sigma's weak spot with noticeably hazier details. Bokeh looks awful for both with doughnuts (strong outlines) everywhere, though if I had to pick the least worst it would be the Tamron. Not going to sell my 24GM anytime soon...

28mm @ F/2.8, Tamron top, Sigma bottom
Tamron is again slightly but noticeably superior in terms of sharpness. Sigma has poorer OOF transitions, but Tamron has marginally more LOCA in OOF areas (though again both have less than ideal doughnut bokeh). I'd give a win to the Tamron overall.

Very useful comparison, thanks for that! Looks to my eyes that a good deal on a used Tamron 17-28 is a good deal indeed.

Indeed. My dilemma is which one to keep and which to sell, since both are fantastic lenses. Having watched the Dustin Abbott video comparison again, my findings and conclusions essentially confirm his: both lenses are fantastic, the Tamron has a slight but visible edge with respect to IQ between 24-28mm, the Tamron has slightly less distracting bokeh, the Sigma has objective advantages in terms of zoom range and an AF/MF button.

I really want to like the Sigma more as it is newer and sexier (or "psychologically more exciting" as Pav SZ the YouTuber describes it), but the mind says Tamron as it is a heck of a deal at current used prices. I'll probably settle for the Sigma, and justify it in that I anticipate using it mostly at the 16-20mm end and I have a 24GM for more demanding 24mm applications, but the 16-28 is decent enough for snapshot use.

One more 24mm sample from the Sigma followed by Tamron, note the latter is sharper, more contrasty, and noticeably a less busy lavender background:

Wonder how long before we see a G2 17-28 from Tamron. I have the button on my G2 28-75 setup so if you hold it in for 2 seconds it switches between AF and MF.

We're in lensvana now a-days.

Yeah I wasn't anticipating the bokeh win for the Tamron, but those two photos demonstrate that quite clearly. The new Sony 16-36/4 is of interest to me as well, but the Tamron can be found in Vancouver in the $800-900 CDN range. Food for thought!

Yeah, I think we really are. For someone like me, decisions are interestingly fraught because one can compare, debate and argue minute differences in any number of categories. A good problem to have. I think if you told me even 5 years ago that I'd have so many superlative lenses to choose from, I likely wouldn't have believed.

I mean...all that said...still no 28mm...so maybe the Tamron is the substitute until one arrives

If one ever does...

For me, a lens like this is about the wide end. I have the Sigma, and I had the Tamron. The FOV difference is very noticeable, as in examples above (Thank you, ryanli). The 16 end is why I bought the Sigma, and that's where the lens is at its best. The bokeh can be distracting at mid distance, but it can be softened in post, and honestly, I shoot it far more at f8 than I do F2.8. I think Sigma has gone for different objectives with their 2 C F2.8 zooms. The 28-70, which I also have, is all about rendering, with really nice bokeh for a zoom. It's for taking pictures of people. The 16-28 is about resolution and detail and getting it all in focus. I find them to be an excellent pair. I love the fixed size of the 16-28, and I would say it's more than good enough for my uses on the longer end, and excellent at the wide end.

Very interesting counterpoint. I think you're right about Sigma's design brief being different for their two C zooms.

Again, choice is a good thing, though you're not making this easier...

Thanks, great to hear from folk like you who've "been there and done it" switching from Tamron to Sigma, and I think your analysis is sound. On the Tamron side, I'd say that the Tamron 17-28 renders quite similarly to the Tamron 28-75 G1, with very high contrast and achingly sharp details, but decidedly superior bokeh (@Dave Sanders I too was pleasantly surprised).

And to those who are expecting a Tamron 17-28 G2, it looks like Tamron is going to give us something even better...!!? https://www.sonyalpharumors.com/rumor-tamron-will-announce-a-fast-wide-angle-zoom-this-week/

Maybe a new version of their 15-30F2.8. That would be smart and enticing, depending on the size.

That's what I'm waiting for - I kinda hope it might be even a bit wider (like Canon's RF offering), maybe at the cost of aperture. I was surprised Tamron announced 50-400 first, let's hope this rumor is true for a perfect complement to 35-150 .
I was recently wondering about giving up my Sigma 14-24, as I would use 35mm on the long end a lot more than I'm currently using that extra 2-3mm on the wide end...

Hmm... Looks like Tamron is going the other way with a 20-40F2.8. https://www.sonyalpharumors.com/leaked-first-image-of-the-new-tamron-20-40mm-f-2-8-di-iii-vxd-lens/#disqus_thread

That's a bummer (better for my wallet though) .
