I want to show you what the differences you will get between AF and AF plus Eg-S correction. Center 5D2 AF point was used. She was about 7 meters away, both are 100% crop of [email protected]
Focus screen aid is always worth it if you shot fast lenses. 1/3 shallow dof and/or calibration error is so hard for lesser 1Dseries AF firmware to correct it. This applies to any AFMA system we have.
You can see 50L is not less sharp than any other canon fast lenses as people claimed and that the point try to make here.
While we at this, i have not seen any focus shift evident that makes my foto less sharp either since the day my 5d2 wears the Eg_S contact lens.
mttran -- I can see the first photo is way out of focus, and the second one is sharp. But I don't get what a "focus screen aid" is, or how it improved the AF. You saying you used the "S" screen for the second shot, and it nailed focus, or is there some firmware I don't know about?
I've always been reluctant to install and "S" screen due to slower lenses I routinely use. I understand the S improves MF of fast lenses, but noticeably darkens slower ones, and I need the best light on slow ones for AF and MF.

Gust -- I think that is just a joking euphemism meaning the Eg-S focusing screen, mounted in his 5D2, makes focusing easier since it was installed.
+1, Jim and Gust: sorry for the confusion. The S screen has nothing to do with AF function but help us to correct the final focal plan after CAM does its AF part.
Thnx, but working with a and a 1D X, I hate the back focus.
adjust the AF by Canon Europe, they say: the AF in my 50/1.2 is exact good.[with the 1DX]
using the 50 in the studio [f8.0] its perfect, but outside using 1.4-2.8, I hate it!!
what to do? several times my thoughts saying me: sell it, but I love the colours and the unsharpnes in the back so much. wish it was that sharp as my 35/1.4
Gust: 1DX spot focus option should fixes this shallow dof problem, have you tried it with 50L?
Great AF is one of the reasons why i keep my 1Ds2...it hardly missed anything in static mode. Here is handheld 1Ds2 & 50mm @ f1.0 and subject was 15-20 meters away
Yes, here is the exif = f/1.2, 1/100, iso 1600.
And this one is wide open also. http://i35.photobucket.com/albums/d180/diascarlos/IMG_2886.jpg
I have the 24L, 85L and 135 L, they are sharper than the 50L, but I think that the fifty is the best lens for low light .
With Eg-S help after AF, i can see subject skin texture at 100% wide open crop. So if you had sharpness problem with your 50L at any aperture vs distance, i would blame on the body AF firmware instead of the lens itself.
