1) in flash menu, auto detecting lense length doesn't work, like 50mm lense suppose to let my 580ex zoom to 85mm, but it didn't happen, the flash stayed at 50mm
2) my 50L, are completely two lenses when in low light and in ourdoor ambient light, in low light I have to add +10 in microadjust lense shift, in good light there is no problem.
3) 7D might not be able to focus objects over 25 meters, but I don't have longer lense, for in 50L's f/1.2, all that is over 25meters might be in hyperfocal distance so I really couldnt tell, but my two 50/1.8 lenses couldn't focus over that distance, and that occurs 100%.
