mttran -- Nice shots! Have you tried it at middle distance or infinity wide open to see how it does there?

Thanks, i have no problem to get the best sharpness of 50L at any distance as long i don't rely on 5D2 AFed alone. With Eg-S help... 50L sharpness can go very very far with it.

Here is an infinity wide open shot ...captured by 5D2 AF only

Don't rely on Canon cam AF while testing your 50L wide open sharpness. This is the message i try to get across in this thread.

You can see in real life: wide open dof of most fast lens does not work/look the same way that has been shown in some review sites. Another word, their MTF 2D charts does not help much at all

After I did some MFA, I find the sharpness of this lens at f/1.2 is very usable.

Mine's just fine. For AFMA, it needs only -2 on my 1DsIII and 0 on my 1DIV. Haven't done my 1DX yet.

Then what is it you rely on?

I've been back and forth on this lens for a long time. Really would like to have it, but its reputation isn't stellar.

Just answered my own question - I read up on the EG-S screen...

mttran -- Thanks for the ship photo.

I have no problem with mine using AF on the 5D2 at -6 MA correction. Works for near and far.

I don't want to use the Eg-S screen, as I use a few slower lenses that would look extremely dark with it.

NIH23 -- I think it is worth it. The wider aperture "look" can't be matched by the 1.4. But if you are using mostly 2.8 and smaller, the 1.4 is about the same or better IQ. On the practical side, the 1.2L has a better, more robust USM motor.

Hi Gust,

Your best focal plan is 1/3 dof and it can be easily missed @ f1.2 with cam AF. I use Eg-S focussing screen to monitor and correct the final focal plan.

i have sold and bought multiple 5d2, my 50L AFMA was all over the place with some of them but it works like a champ with the current boby.
