Do you want crops of mine at 42MP FF? Not sure if it's helpful for you
Yes, that would be great. Show me extreme corner crops at infinity (f/2, f/2.8 an f/4). This would be great to confirm what I see with my copy. Is your copy well centered? Even if it's not, just show me your best corner. On mine, they are equal.

These lenses are very intriguing. I picked up a copy of the 45 2.8 and I think a it's great, inexpensive and lightweight lens for everyday stuff. But these new f2 lenses intrigue me even more, as I think I'd love the 45 2.8 if it was f2.
What are most of you buying these for - to replace larger, more expensive options (24 GM, 35 GM etc) or to use in conjunction for less critical work? Or both
At this point, I mainly buy lenses to temporarily reduce GAS. I have too many lenses as is.
The Sigma Contemporary lenses offer a unique combination that is missing from bigger, heavier and more expensive options like Sigma Art, Zeiss, and Sony GM.
* All C lenses are under 1 lb.
* All of them have top IQ and beautiful rendering.
* Metal build quality and a beautiful retro inspired design.
* Way more affordable than GM, Art and Zeiss lenses.
I could definitely see picking up this 35/2 rather than the 35 GM. While the latter is faster and likely bests it in overall IQ, the Sigma is small and affordable, the build quality and feel of the lens is great, and it's still exceptional in IQ according to the reviews. I don't shoot 35mm much these days, having largely moved to 28mm, but if I did I'd almost certainly pick the Sigma over the GM for myself.
I think the 24mm looks like it has similar appeal to the CV 21/3.5. Just a small, light, well-built wide angle gem that's easy to bring along on a hike. I still prefer the CV personally, though, since I prefer 21mm over 24mm in my kit.

In your edits, did you touch the vignetting at all? If so, how much correction was required?
Only in the f/3.5 pictures I added about 20 to 45 amount of correction in LR (midpoint to about zero). Otherwise (at f/5.6 and smaller) none at all. So I wouldn't personally call it an issue. But that's just me. Sure, LR says it has applied "built-in profile" which I have no control of. But at my standards, I have little to complain about the overall IQ, which is pretty stellar. Mine also seems sharp from corner to corner without any decentering issues. And rendering, contrast, flare control etc. seems very similar to Voigtländer alternatives like 21mm Color-Skopar.

Earlier I had the CV 21/3.5, but I found it hard to focus manually, especially as a general use wideangle. I had hoped for a similar autofocus wide angle and this little Sigma seems to have nailed it perfectly. A bit less wide, but otherwise very similar. Seems a bit sharper too, but doesn't manage to create sunstars as well, as expected.

I have the crops but I'm hesitant to post without testing another copy on Monday. However, I can already say it's a great landscape lens because it's flat field and at f/4 it's optimal and very sharp across the field. (61MP)
Fred, My copy is well centered as well. I can post a few with SL2 at extreme corner later today. I think i have seen sharper lens at f2 at this extreme corner. Both 65 and 35's extreme corner seems benefit from stop down until f5.6. (maybe f4 for 65) Center is peak at f2.8~f4 for both. Mine are L mount with SL2 sensor stack.
However, I consider both result are academic to me, they are just beyond approach for landscape need given most of time I am fighting DOF.
65 is almost felt too sharp for portrait for me at f2. I seems used to Lens with SA for this use. However, it does have well behaved bokeh. I have zero complain about all three I have and will for sure use them a lot for foreseeable future. My curiosity would be how this sigma 35mm compare to Nikon 35Z. I think only 35Z could give it a fight, they two behave very similar in sharpness POV. But Nikon one is larger and offer not so lovely build. Sigma get this set nailed.

Really tempted to cancel the 35gm pre order and do that but I am curious to try the gm to at least rule it out
Me too, but the wait for the GM may be longer than expected. I called Adorama to see if they can tell me where in the queue I am for the pre-order and they said that due to the demand, they cannot estimate. I also just saw that the manufacturer ship date changed from 2/15 to 2/22. Hmm.
I can't say that the Sigma 35/2 tempts me right now.
My kit is the 24GM, Tamron 35/2.8, Voigtlander 40/1.2, Sony FE55 and the Sigma 105/2.8 Art with the A7riv.
I've found the Tamron 35 to be a very practical lens, even if its not nearly as pretty as the Sigma. I'm happy to give up one stop for a lighter weight and a lens that has no optical issues to worry about at any aperture. And I've always got the Voigtlander if I want fast.
So I thought the Sigma i series was just not that interesting to me...
Then Tim had to post those 65/2 images. Now I can't stop thinking about whether it would be better in my kit than the FE55.

I don't see the results from lenstip with my copy (which is perfectly centered on my A7R4) but it performs just like the ephotozine's chart with a very slight improvement from f/2 to f/2.8 and a big jump from f/2.8 to f/4.
Also with the lenstip test, I don't see the big jump at center from f/2.8 to f/4. With my copy, the lens is already optimal at f/2.8 with pretty much no changes stopping down to f/4.
I believe both lenstip and ephotozone use charts at close distance for their results.
How does your copy perform at infinity? Similar to ephotozine or lenstip?...Show more →
Not sure yet, Fred, I’ll start 40xFL testing soonish, but for now I’m just enjoying the fact that it’s fine at any setting I’ve used.
One source of difference between chart tests aside from sample variation and tester error is that some refocus for each chart position, and others focus at centre, Opticalimits refocuses, for example, and then comments separately on field curvature. I don’t know what LT o and ePhotozine do. Ideally I would like to see both refocusing and centre focus, they give good info. Myself I refocus at close distances on the basis that the subject is more likely to be isolated, and focus at centre for infinity. But if I had more time I’d do both at both distances.

That would not make any difference with the 35/2C since it has pretty much equal corner resolution when the subject is focused at center or corner. (same infinity distance)

Unless it has a little FC at closer distances while being flat field at infinity..

I never thought i’d be saying this but i’m in the same boat - I have the Nokton 50/1.2 in case I need really low light, and I think this combo is becoming increasingly appetizing given size/performance/aesthetics/price.

Hi Nehemiah,
I received a second copy just to confirm how the 35/2 performs at infinity and it did just as good as the first copy. Now I can post the review crops with confidence.
The performance from my infinity test is very similar to the ephotozine's chart and different than what lenstip posted. I know the former uses IMATEST at closer distance which suggests that the 35/2 DG DN performs similarly at close and long distance.

Sure. My lens also is as you describe and ephotozine's as well, and my copy is perfectly centered. I have crops from f2-11 if you'd like or something changes. I already shot the infinite scene.
p.s. Zhanyue's idea for an i-series image thread is great!

OK, I will start that thread if nobody do that before I post. It will be on Alt and Sony forum.
I will post a few crop later today once I have those available but also curious about Fred's and your results Mine is SL2, I think Sigma will optimize their lens for FP but at 24M I don't want waste my time.

This is how mine look. Curious if Fred's 61mp sensor shows much of a difference.

The 65 would gap better with your 40 and 105. I haven't been using the 55 much, but the Sigma has noticeably less LoCA. It would also feel more like your CV 40 (I have the CV 50/2.) But if you are happy with the 55, maybe just stay pat.
I really like the Tamron 35, and plan to use it for hiking and waterfall shooting. But after handling the 45 and 65, and seeing the rendering....I'm willing to give the 35 a try.
I have the 105mm f/2.8 Art and the 14-24 as well. Seems like I'm on a Sigma kick.
