So, one blogger who hates the 135mm focal length, as well as his followers. I had to look several times to be sure I wasn't on Ken Rockwell's site. This could've easily been written by him.
I shot the 135mm f2 L a ton when I shot Canon. I shot the Fuji 90mm f2 a ton when I had it in my last prime kit before giving the 2.8 zooms a go. If I go the 90mm route, I know exactly why I want it and what type of shots I want it for. I could have used a 90mm for shots at the wedding I worked tonight. And the auto focus of the 90mm is far better than that of the 56mm. Prime choices are personal to the shooter.
