#photography nerditry:This isn't really for my style of photography, but I recently had the chance to play with the new Sony 50-150/2.0 zoom lens, and wow - sharp and fast in a single zoom covering normal to moderately long. It would be game changing if I were a photojournalist or street photographer, replacing the ubiquitous 70-200/2.8 that lives on the "long" body.I assume Nikon and Canon have something similar in the works.
