Just got a Rokkor 58/1.2 the other day. Here's an unscientific comparison against a Carl Zeiss Planar T* 50/1.4. Same settings, both wide open. The Rokkor shot was straightened a bit, but both shot in raw and processed in LR and otherwise untouched.
The Rokkor constantly gives a warmer tone despite the sun hiding behind the clouds in the Zeiss shot.
Anyway, not really trying to make any loud statements.. just sharing something I found interesting. For what it's worth, I really love both, but the bokeh quality award goes to the Rokkor

that looks about like what i would expect from each lens. does your rokkor have some yellowing due to a thoriated rear element?

Yup, a bit. That thorium issue used to bother me. I couldn't care less anymore lol. But my 5D couldn't handle the color cast when shooting in warm lighting despite being set to tungsten wb.

yeah, i really kinda liked the warm cast for portraits, but the lower contrast and lower T stop when i needed it made me switch to an unthoriated one.
MC PF 55/1.7 wide open, not sure why i like this shot of nothing:

Maybe it's the strong contrast between the red container and the floor. I actually thought it was a floating thing
Re lack of contrast, that I could live with. It's the difficulty in nailing the focus that's frustrating me so much. So much so that I ripped out the af chip from another adapter and stuck it to the Rokkor! That helped but I still ordered an ee-s screen.. and immediately after I read about the possible need for shims to get a more precise focus. Bugger!
The focus should have been on my daughter's back, not her bum. Oh well.
Yup, one of the big annoyances of a DSLR, a miss-calibration between the OVF, Sensor, and PDAF sensor, proper testing on a tripod is the only way to know how bad it is.
You could send it in to calibrate the focus screen.

Eagerly waiting for a FF NEX.
I can imagine the amount of shutter activations I will save if only focus is spot on each time. I only have to worry about composition. I'll have to do that tripod method soon.
No doubt full frame mirrorless cameras are just around the corner.

The Ee-S will make a huge difference. You may not need to shim it, but if you do it is quite simple. Don't get discouraged. It is well worth the effort. Believe me. You don't need no stiiinkiiing live view.

Thanks Cogitech. The screen arrived today and initially I thought there wasn't a noticeable difference ('was too paranoid to scratch the screens by comparing them side by side lol). Then I realised it was subtle, but clear enough. Making test shots, keeper rate was high. And fortunately it did not need shimming! As expected the AF chip on the lenses weren't really reliable, but much more tolerable with the new screen.
