My current lens inventory consists of the Oly 60mm macro, 9 mm BCL and the kit lens that came with my old E-PL1. For adapted lenses I have a Minolta 45 mm f2. What I'm missing is something wide and fast for across the table shots in social situations. My budget is no more than $250 for new or used, so I am currently considering the Sigma 19 2.8, Panasonic 20 1.7 and 14 2.5. From what I've read the 14 has sharpness issues and I worry that the Sigma may not be fast enough. I would appreciate any advice or input.
