Oh, there are a couple of 50's that are sharper, and with far better micro-contrast than Canon's. Canon really needs to update their 50/1.4.
Sure, but none with AF on Canon EF-mount, or on Nikon, or Sony, or Pentax... They're all ancient designs, and perhaps Nikon is the worst offender; they re-sleeved their old 50/1.4 formula into a new 'G' body, but didn't really upgrade the optics, like Canon, except that Nikon's transition is much more recent; same with their 50/1.8G. So they have lenses that are optically equivalent to Canon's ancient designs with upgraded built quality- woohoo!
For Canon's part (and unlike Nikon), a 50/1.8 IS USM has been on the rumor mill for some time; it may or may not be real, but given the advances that Canon has been able to make with their current trio of stabilized primes, like the 35/2 IS which is a true next-gen design unlike Nikon's 'has been' 35/1.8G update, it's not hard to believe that Canon is seriously willing to keep pushing forward.
If only they'd apply similar resources to upgrading their sensors, or to bribing Sony for some Exmors.
