Cruel conversion -- The lens was JB Welded to a Rollei QBM-EOS mount.
The FL 58mm f1.2 was the first f1.2 lens Canon made for its reflex cameras. It works on Canon FL as well as FD bodies, and now Digital. Compared to the FD 55mm f1.2 S.S.C and the Canon nFD 50mm f1.2, this 58mm f1.2 lens is softer at f1.2, which is expected. It would have been a failure if the next generation lens is worse than the lens it replaced. There is a bit of blooming and purple fringing wide open, again expected for a lens this age and class. One stop down makes a huge difference, both in terms of sharpness and bokeh. I find the bokeh more pleasing with the 55mm f1.2 SSC and the nFD 50mm f1.2 than this lens.

I am sure this lens was not designed to take pictures at f1.2 in the middle of the day, which was what I did. In low light situations, it should perform better. So far, I didn't do much testing with this lens. The corner performance is not yet known.
