There’s no doubt in my mind Canon is working on a couple of new 50mm lenses.
This is good news since none of the present lenses are worthy of my money.
-50 1.8 = a toy lens, too few aperture blades
-50 1.4 = more expensive toy lens, prone to breaking (also had one and didn't like it)
-50 1.2 = expensive and with problems like focus shift
-Sigma 50 1.4 = could be good if by some miracle one could find a decent specimen
If I'm not missing anything, these are the autofocusing lenses for Canon at the moment. So after that short listing I welcome new additions to the lineup (and IS of course, it's a life-saver for me).
