Greg, as a rule of thumb a 10% difference in MTF50 is barely detectable in a reasonable size print or comparing 50% jpgs on a monitor. There's variation of course but that's a good rule of thumb.
The other reason I like that number is if I take a given camera and lens and take a number of autofocus shots of the same subject, rapid fire, they'll vary about 10% in sharpness.
For both reasons I think a difference of less than 10% has little practical importance.

Thanks for all the samples, Gregg! The shots of the children are fantastic. 
THATS what it's all about.
(Ok, and I really like the spidey shot. How big IS that thing??!)
Cheers,
Michelle

Hey Michelle,
You're right! It's all about the children!! And they let me know often enough, too!!!!
The spider was no bigger than a quarter. and the shot was at MFD, too.
Here is a pic of the spider at f2..adef difference, but sot huge

I do like the f/2 image. The bokeh is still nice, but the extra dof makes the webbing on the leaf pop out nicely.

It's about time someone took the "Picture of my cat" test! I was getting nervous. I will now definitely get a cat.

Don't knock it!! They make great still subjects!! I even got Duncan to look at me!!

Greg, i think Sigma should use some of your images to promote its lens.
Great samples, thank you very much!

@ Greggf:
Yes, looks like Duncan is getting bored about posing in the last picture. But for the pic right two frames above, he did wonderful!

On the swing pictures, do others agree with me that the Zeiss contrast is far superior? I would go so far as to call the Sigma contrast harsh, at least in that image.
I cannot see the difference, honestly.Was trying hard yesterday....

@Ralph and snoochenko...thank you for the kind comments!
I will hopefully do a small comparison between the Sigma 35 and my only other current 35-Nikon 35 1.4ai-s. the Nikon has size going for it, and it is really sharp from f2 and smaller. I will try to get that done in the next couple days.

thanks for the great sample photos Gregg!
seems like the new Sigma 35 has better-controlled CA than the 35L

I wonder where the new Sigma 35mm leaves the Samyang 35mm f1.4?

I had 2 copies of the Samyang, and let me tell you, that lens is really fantastic! Nothing better for the price! Sharp wide open, and from f2-f5.6, it too would be pretty hard to beat. The corners were great, almost wide open!
Here is a link to my picasaweb where there are albums from both the Rok 35 and Zeiss 35 1.4.

The SIGMA Merrill DP2M and many hundreds of flickriver images prove they know all about bokeh as well as high resolution.
The early status of this new SIGMA 35mm f/1.4 AF lens is quite interesting and truly warrants a closer look from all thoughtful artists.
A KEY MARKER of quality in this lens is the over-the-top critique from a CANON poster who (1) had no access to the lens (2) used only a single image upon which to base his negative "Impression" and (3) no mention was made of the clear SIGMA price advantage nor of the design advantages which inure from added elements, ED and asph features.
New competition always triggers such basher moves and we should see this as a good reason to look even closer at this product. The filter size (67mm) feature nicely fits the Zeiss ZF.2/ZE MF line.

Nice link - Siggy looks a tad better at 1.4 and f/2 in those samples, though focus variation could be a factor.

So to exceed the performance of the Sigma, the new 35L mk II will need to hit the $2K mark and if an extra $1100 is worth what, maybe a bit smoother bokeh, as it's hard to see what else could be done to improve the Sigma, then good luck to you. Sigma tack sharp wide open, has great contrast and colour and apparently AF speed is fast. For me now 35L is of no interest. It's down to the Sigma and new 35 f/2 IS.
Too bad the new 24 and 28 weren't f/2 as well.
