After a month with the A7, I'm still juggling 50-55mm lenses, trying to decide which one I want whenever I head out the door. When I'm headed out to a dimly lit bar to catch some shots of my fellow musicians, the choice is increasingly obvious: the Canon FL 55/1.2. Robbie DaCosta by Jeff Addicott, on Flickr Dancers by Jeff Addicott, on Flickr Full Frame Selfie by Jeff Addicott, on Flickr Paul by Jeff Addicott, on Flickr This lens features a click stop at f/1.4, which I use quite often. You might ask: if I want f/1.4 why not just use a cheaper, smaller, more common 1.4 lens? As I try out various fast lenses, I am finding that a faster lens stopped down, even by half a stop, performs better than a slower lens at the same setting, wide open. (My old Leitz Summicron-R lenses tend to degrade the least out of all my fast lenses when wide open, but they still get easily beaten by a faster lens set to f/2.) I'm sure with a mediocre faster lens one could produce an exception, but this old Canon is definitely not mediocre. Last I checked, these are all over eBay in the $200 neighborhood.
