Some people wonder: "Yes -- this lens is sharp and all. But wouldn't the other quality fifties be equally sharp at f/3.5 and upwards?"
I have to personally conclude that yes, they are sharp but no fifty I've shot can render like this while being equally sharp. Sharpness at focus and the pleasantly MF-like bokeh along with transitions.
Throw in the lightweight build and ease of use, this is a fine fifty indeed.
