^ I know how you feel, lenses are usually something you do not lose value in. This is just such a HUGE shift for Sigma and now with the release of a new 30 1.4 !!! Exciting times at Sigma.

I shot it at a Bat-Mitzvah over the weekend and I was very happy with the performance of the lens. I have not done all of the insane testing like everyone else has in their thread *LOL*.

I have shot more images of text than I have with any other lens !!!

Here is a consolidated test from my copy of the Sigma 35mm. Ran each test twice with consistent results.

Can you add two or three sentences to help me understand what the graphs are saying? Why so different test of the same thing? Thanks,


It's not a photo until you print it! :cool:

Pages 1-2:
Ran the program twice and the test results indicated that the best Micro Focus Manual Adjustment that produced the sharpest or detected the most contrast is @ -9 or -10.

Pages 3-4:
Ran the program twice and the test results indicated that the images were the sharpest or detected the most contrast is at Apertures f/2.5-2.8

Pages 5-6:
Ran the program twice and the test results indicated that the lens AF is 99.1 to 99.2 accurate.

Thanks, that really helps. So, basically, you have to MA (-10) when putting this lens on the camera and stop down one full stop to get almost 100% focussing. Any idea on how this compare to a Canon 35/1.4 L lens?

Keep in mind... these settings only apply to my copy lens.

I unfortunately do not have or ever tried a Canon 35L so I cannot make a comparison between the 2.

It depends on WHICH Canon 35/1.4. That's the whole point behind MA, lenses and bodies aren't exactly the same (and we shouldn't expect them to be).

LOL. Word :cool:

Ya...word.....:cool:

I guess I'm just not one of the lucky sigma lottery winners or I'm extremely critical on AF issues. Hmmm I noticed Ed Radar dumping his sigma 35mm hmmmm LOL! He has something else now.

When a 35mm red ring mk2 comes out I bet early S35 adopters will whine about the $$$ of the new canon mk2 but have a solid performer in their possession. LOL

I tried so hard to find a solid sigma. I tried......

I won't be one of those, my S35 is perfect.

And you haven't tried this sigma yet ;)

Aside from the weird reaction to my hallway lighting, mine seems great. I've now tried all my other lenses in my hallway too. They all have the issue too, but to a much much lesser degree.

I'm guessing that is because they are all f2.8 or less, and the 1.4 is just so noticeable. I will concede that my sigma 17-50 2.8 OS (at 35mm) is better focused than this sigma 1.4 35mm is stopped down to 2.8. (Only in my hallway) Why? I don't know. I don't care. It works fantastic everywhere else. For the price difference I can live with it.

But I MAY return it anyway. I shoot with a 7D, so I may return it and wait for the new sigma 30 1.4. If its anything like this one, I can save probably 30%. If its not, I can just buy this one back.

As an amature, shooting for enjoyment, I don't want to spend 35L money, and certainly not mk II money when that comes out.

Haha...my 35L is perfect :) Sadly I find the 35mm focal length not very stunning but its a bread/butter focal length that delivers semi-wide normal "ish" perspective like a 50mm. For newborns I'll use a 35mm, 50mm and 85mm and 100macro for the sake of minimizing distortion. Events I still prefer 24mm.

If sigma wanted to rufffle feathers they should make a 24mm to compete with the 24Lmk2.
