I've had my 30D and 85mm 1.8 for about a month and after shooting with it for a while, it always seems like I'm way too close to frame the shot I want. Plus this lens won't focus at less than ~3ft. which is kind of irritating. Should I keep this lens and save up for a 5D? or should I sell it and get the 50mm 1.4? It seems like Full frame will solve all of my problems because my 17-40 f4L doesn't seem quite wide enough for interiors or architecture.
