As do I.

I suspect it is a matter of "Performance does not increase as dramatically as it is stopped down as compared to such-and-such Zeiss/Leica/etc. lens, therefore it is lackluster in a relative sense, not an absolute sense."

This seems like a failure in communication, not a genuine difference of opinion on the lens.


It might not be a Zeiss, but to say it does not improve much with stopping down is a bit of an exaggeration IMO.

BTW, Carsten, I won the race!

There was a race?

To 11,000. Just some silly banter, really.

Well, that puts me behind a little. That's quite the milestone Paul. It's nice to have you back.

I know, I was being silly. But the race to 15000 is still on!

About the Sigma, I can only say that when I first bought it and was shooting it wide open, I was very pleased with it, but when I stopped it down to get more sharpness, it only sharpened up marginally and I was pretty disappointed and surprised. I guess I am used to macro lenses and Leica and Zeiss lenses, and the Sigma just doesn't deliver anything like the stopped down sharpness. Maybe the newer Sigmas are better (85/1.4, 35/1.4).

Some samples from the Sigma 35mm f1.4 here.
Looks promising to me.

Nowhere near 15.000 posts, this actually is my first on this nice and friendly forum.
As for the images in the link above, I think the new 35 mm shares much of the look of the Sigma 50 1.4 especially concerning colors and contrast. The bokeh seams a bit less creamy, which is to be expected due to the wider angle.

The creamy boke of the 50/1.4 was a selling point for some, but a negative for others; those who prefer more texture and action in the boke. It could be that Sigma is trying to aim slightly more centrally with the new design.

Welcome, btw!

Great news! I'm particularly impressed that EVERY single lens is quality tested:

"Every 35mm F1.4 DG HSM will be checked using Sigma’s own MTF measuring system, “A1,” as will all new lenses under the Global vision categories. This system uses 46-megapixel Foveon direct image sensors to pick up previously undetectable high-frequency details for quality control inspections."


So they're testing it on a crop sensor 15 megapixel camera?

This new Sigma 35 1.4 looks to be at least the optical equivalent of the Samyang/ Rokinon 35 1.4 but with much better build and, of course, AF.

looks really good. if i were an AF shooter i'd definitely be interested.

i'll keep my c/y 35/1.4 though even though i could sell it for more than the sigma will cost.

If you read the PR, they move the sensor and check all 4 corners as well as the center crop.

The Foveon sensor is useful for this application because it can detect all colours at any given location. I.e. it offers much higher precision near the edges where chromatic aberration becomes a large factor in lens sharpness. It's a much better way of testing a lens than bayer array sensors.

Looks fantastic, Bokeh seems decent too

WOW! I AM AMAZED - The Sigma looks like it equals or beats the Contax in just about every test. - That is no small feat!

Very tempting lens indeed if I had a dslr. Sigma is on the flow!

Canikon have serious trouble now. They are not only lose body market but Lens now. Just look at this performance make you wonder how come Nikon can ask $1600 a piece with uglier build and similar performance at best.

Don't let me even mention canon 24-70 f4 cost about $1500 with more plastic in it?

Agreed. I still slightly prefer the Contax, but the Sigma isn't bad at all.

In the comparison with the Samyang it seems that the typical Sigma yellow is still there: http://lcap.tistory.com/entry/Sigma-35mm-f14-vs-Samyang-35mm-f142
I wonder why it doesn't show up in the comparison with the Contax (maybe WB was equalized in that test?).

Also, the Sigma seems to have some wavy field curvature that makes zones D and E lass sharp than the extreme corner in zone F. I would like to see a comparison at infinity though.

Longitudinal color is much better corrected than the Samyang, but the focus transition looks quite different too.

I don't know the Contax 35/1.4, but I have a Contax G 90/2.8 that I like on my NEX 5N.

But I thought the Sigma pretty much destroyed the Contax 35/1.4 on sharpness to the point that I wouldn't even consider the Contax 35. Bokeh appeared to be very similar so I don't think the Contax made back any ground after losing so much in sharpness.

Hmmm.
