Thanks Keith. Does anyone know if there's a big difference between the 65mm L-A and the standard 65mm? My budget for a wide-angle was about $250. It seems the L-A lenses go for at least $350 usually.
I don't mind fixing lens distortion digitally, since my workflow involves scanning. That said, if the 50mm is noticeably less sharp than the 65mm (likewise with the L-A vs non L-A), that can't be fixed afterward.
