^Yes, the ring holds the rear element in place. As you approach infinity, the rear element gets closer and closer to the mirror. When shaving, you have to be mindful of the arc path of the mirror and where the retaining ring is seated when fully tightened. I think other people may have gotten away with having it clear at infinity with just modifying the retaining ring, its a bit hit or miss.

The retaining ring is also brass, which isn't as strong if you file away too much of it. Sharpies markers and a lot of patience is my approach.

Can the Rokkor be adapted to Sony Alpha?

no, just like canon it needs a mount conversion. there is no problem with mirror collisions on FF sony's at infinity though.

the conversion is pretty easy, but there is no kit for it like there is for the canon:

For reference, I just threw the FL 55 @ 1.2 on my Fuji X-E1. Simple, handheld test wide open, RAW via Aperture with zero adjustments.

Damn sharp lens. Plenty of LoCA wide open (stopping down helps quite a bit).

And 100% crop:

thanks for the pictures. I almost forgot about the FL thinking about the rokkor so much.
It looks pretty good for wide open.
I wonder how the bokeh is on the FL.

Here's a conversion kit for Sony Alpha: http://www.rharris-images.net/58mm-f1-2-rokkor-adapter/
I've seen another source for them but don't have the link handy.
