p.1 #1Sony 35 GM vs Sigma 35 f2 DG DN

I have the 35 GM for about a week until my real one comes in April.

Here’s a size comparison:

Thanks! And wow the GM looks really smooth...
Any thoughts on AF?
Just read the last sentence, I guess the GM will come in handy for "documentation" purposes then

(and congrats of course!).

Wow, even at f2 the GM looks noticeably smoother - thank you for the comparison and +1 for the GM! Also, congratulations!

Is this using the demo/pre-production model of the 35mm GM?

The GM does look better in my eye for all the tests.

And it should being more costly and a GM.

The Sigma does an admirable job here but this brief comparison also makes me feel better about sticking with the GM pre-order. So far looks great. Creamy out of focus areas. Rounded bokeh balls. Contrast is looking great. If you are taking requests, it would be great to get a little more transition zone comparison, and after that, corner sharpness. Although that surely will be done by Fred and others eventually too.

Thanks! Yes I’ll be using the GM specifically for the birth

I’ll post more on AF once I’ve used it more. But so far, it’s rock solid and very fast.

Agree on both fronts.

GM is a lot bigger than the sigma, so as a compact option, the sigma is a much better choice and stills delivers optically. Degree of blur difference is not substantial at f2 vs f1.4.

That said the GM bokeh does look good in these samples and that's the area I was most curiuos about vs the sigma 35 f1.2 (the bigma). keeping my GM pre-order for now, though the sigma 35 f2 has personally earned it's keep.

You did a great job here, thanks for the effort.

A big focal plane with billowy abstraction of objects floating in the ether, or a smooth draw with still well drawn remnants of 3D and objects for context - what do you like in your bokeh? To some extent, any modern f1.4 lens has to play to its audiences' wishes: massive separation with a strong focal plane and soft backgrounds to work with each other.

Congrats on the baby! Hope all goes well.

I prefer the GM rendering too. I guess it makes sense as it costs more than twice, but Sigma is doing a great job here. It is not like GM completely owned Sigma; Sigma's rendering is nice too.

Sigma's design is so sexy. Looking at both of them side-by-side in the first two images, Sigma is like having a slimmer, more attractive looking sibling. GM is not a bad design, but it isn't Sigma cool.

GM looks really good here. Sigma's no slouch, especially at the price differential, but I'd probably go with the GM in the end.

I canceled my GM preorder because I don't exactly need the lens right now, but I'll come back to it somewhere down the line.

Congratulations on your baby! We just had ours a few months ago and he makes us happier than anything in the whole world. You are truly in for a real blessing

With regards to the lenses, would it be possible to test them both at full body portrait distances to see how the rendering compares? Also if we could see transition zone comparisons that would be amazing!! You're the real MVP!

Oh I almost forgot! Could you compare how the field of view changes with both lenses at the same distances? Like once you get closer up, say for mid length portraits. I'm concerned about the Sony's terrible focus breathing.

Thanks for uploading these.

It looks like the sigma has a wider focal length, which might also contribute to the GM’s smoother bokeh along with sigma having gone for a more contrasty look.

Did you use a tripod though as maybe the apparently slightly different focal length could just be where one stands.
