Mine is the Canon 300mm f2.8L IS.
Simply stunning detail, bokeh, sharpness and contrast/tones. Really really consider myself lucky to own one![]()
Nikon 24-70/2.8 AF-S, a bit heavy, but a marvel to use ... today got it back from Nikon's service due to front focusing issue at 24mm.
About your 50AF-S, sorry to hear about the front focus issue, but how serious is it?
