So the FL 55/1.2 turned up on Wednesday, and the EdMika adapter on Thursday.
Firstly, good idea adding in that extra ball-bearing. I didn't lose the one on the mount, but my lens had an "issue" that I knew when I bought it (and got it for cheaper). The front ring had come off, only held on by 1 screw (found a 2nd screw in the packing), but the aperture-click ball-bearing was gone. Ed's replacement ball that he so kindly gives everyone fit in the spot nicely, now my aperture clicks again.
I normally de-click my MF primes, but it's going to be useful for my 50-55mm prime shoot-out i'm planning (borrowing my mate's EF50L plus i've got 3x50mm and 3x55mm now), and I might stick with the clicky-aperture for a while (and I can presumably sell it for a profit now that it's complete, too bad I'm in love with it and don't want to ever part with it).
So, three photos that pretty much sums it all up. FL- to EF-mount in 3 minutes, not having practised or even read the instructions, and I was hardly working quickly either.
And a shot I took this morning in the fog, f/1.2, iso100, 1/125s handheld, MFD. I took a lot this morning actually, I think there's finally a different lens to be called "glued on my camera" more than my 70-300L, I absolutely love it...
