mm i think i saw a 50 1.2 or a 58 1.2 at a pawn shop...i think i may to do a double take...how easy is it to convert to EOS? i have a 1d3 so i dont think the mirror hitting will be an issue...great thread!

random..how does the 50 1.2 compare to the c/y zeiss 50 1.4

the 50/1.2 is the easiest rokkor to convert that i've seen. the 58/1.2 is a bit harder but still pretty easy and you can buy jim buchanan's kit to do it.

both lenses are very different in drawing to any c/y lens. i wouldn't even bother making a comparison between them.

Is there consensus that the 58mm is creamier b/c it has 8-9 bladed aperture vs. the 6 of other 50s?

no, the 58/1.2 is creamier because of the optical design at all apertures. in addition the 50/1.2 has harder rings to oof highlights wide open. but yes, the 50/1.2 has obnoxious hexagons at f/2 and smaller while the 58/1.2 doesn't really show octagons until f/2.8 and smaller.

8 used to be the standard for high end lenses and telephotos (except nikon). they would all be better with 15 blades, but the number of aperture blades really doesn't contribute much to bokeh except for the shape of oof highlights. it contributes absolutely nothing when the lens is wide open.

I did a test run of some outdoor portraits I need to take soon on Saturday evening. Thought I'd share them here as they'll all 58mm Rokkor. The photo should "click" through to the series on my blog.

Thanks JR , glad you enjoyed them Sadly, because the weather has turned we weren't able to get out and do a re-run. Every time we planned the weather let us down . I even had to cancel one shoot and put another back until the end of August.. so not exactly how I planned things :/. As you can tell I'm not used to these sorts of photographs, but I think using one lens actually helped (like it often does).

I bought Buchanans adapter for my 58/1.2 - it looks like professionaly made conversion with it. It is worth for this glass IMO.
It does not reach infinity on my 1D III even after adjustments so it might be your case as well! Infinity is sharp at f16 which is not practical. Shaving would help but i do not want to touch such beautiful lens.
I do use it together with C/Y Planar 50/1.4 and both are amazing lenses with different drawing style. Rokkor is really suited for people photography and bokeh itself, has beautiful tones. 50/1.4 Planar is much easier to focus and is quite a bit sharper than my copy of rokkor.

Ugh, somebody please punch me in the head. I bought the local copy of the rokkor 58 1.2. It had way too much dust so I went ahead and tore the thing down b/c the aperture blades didnt work (why didnt i notice!!) and there was way too much dust.. Problem is now it wont go back together for some reason. The outer focus ring doesnt want to screw onto the lense screws and I have a small ball bearing....I have no idea where it goes... my lense is very very clean now!

anybody have a breakdown diagram?

this may help: http://www.pbase.com/pganzel/58mm_rokkor_disassembly

the ball bearing is probably to the aperture ring though there are also a ton around the mount if you remove the short screws in addition to the long ones...

I figured out where the ball bearing goes so at least that is good

I had no issue disassemble/cleaning it.

The way i took it apart does not look like the photos...my helicoid/outer focus ring is separated from front cell/rear cell/iris cartridge...

easier if i took a picture


JLH_9741 by crazeazn, on Flickr

I cant get the piece on the left (focus ring) to the piece in the middle even though the threads are the right size... i tried removing the bottom black portion of the middle piece but still no go.

may need some assistance on how the aperture circumference lever coincides with the shutter? tab...i want to make sure my "cleaning" on the sticky aperture worked before i order the EOS mount..or i will just toss this thing.

Did you happen to try it clockwise? It should go in counter-clockwise.

One way (i do not remember which one) works but you have to try to do it many times. I do remember it took quite a while to me also..and it was very strange to me as well.
