If you have a problem focusing fast glass with the M screen on the a900 you probably need your eyes testing :-).
That is a nice suggestion Wayne. The Rokkor draws very differently to the ZA stuff, so they can't really be used alongside each other in the same series, but it can be supplementary of course as it gives a very unique look. I upgraded to ZA glass in July. 16-35, 85 & 135 have been balancing together wonderfully. My only wish is for something shorter and fast, something like a 35/1.4ZA... I've not much interest in the new 50 in honesty. The Rokkor owns that.
I will dig up the link tomorrow. The one I got you just switch with the original mount, no surgery needed.
I've never linked here before as I feel it would be a bit advantageous, self promoting, if I did so myself, but 'Richard Harris' is me, if anyone hadn't put two and two together. I've been making these for I guess 3 or so years now. As the page mentioned, handmade, made to order... so I don't have a huge stock or anything like that. I simply turn the lathe on and get going as and when. It is completely non destructive, reversible and of course gives you FF + infinity focus, so I think the attraction is obvious, but still this lens is not for everyone. Some people just can't focus is well enough (patience, skill, eye problems), and often that combines to people calling it 'soft' or 'useless at 1.2'. I have experienced some that have a glow at 1.2, but the detail is still there, but of course I personally prefer glow-less as it's just a cleaner picture that way.
Example of real life photo at 1.2 on a900. Very detailed all the way to 12x8. I rarely print such images above that, but it will easily go above.
