50mm f/1.4 AF-S vs AF-D
I'm thinking of moving to full frame from Dx. I already have the 24-70 and 70-200 and I'd like to add a 50mm prime. Since it overlaps my 24-70, I'm, mostly concerned with it's performance from f/1.4 to f/2.8 and I'd rarely use it wider than f/2.
Other than the AF-S motor, what's the main differences between the 50mm f/1.4 AF-S and AF-D?
