Is there anything decent for under $500? Minimum - 20mm, maximum - 35mm. Not really interested in a zoom lens... So..., my options are: 20mm f/2.8, 24mm f/2.8, 28mm f/1.8, 28mm f/2.8, 35mm f/2... I was looking at the 28mm f/1.8... All the reviews pretty much say that it sucks below 2.8, so why not buy the 28mm f/2.8 for less than half the cost. It sounds like the only thing the 1.8 has over the 2.8 is USM and better build quality. Then there's the 20mm. Sounds nice, but... Very strong vignetting (not sure if that will really be bad for me - I add vignetting a lot...). Actually, the 20mm seems like the best choice so far. The 24mm sounds a lot like the 'nifty fifty', but smaller. None of the reviews are really winning me over... The 35mm sounds a lot like the 24mm, but with crappier bokeh... So... For less than $500, it sounds like the 20mm is the only option. ? The reviews for it aren't nearly as bad as the others, it's just a little wider than I really wanted to go. I think I could deal with it though. I hate to ask, but is there a Sigma lens I should consider...? I'm looking for quality on a par with the 50mm 1.4. EDIT Just in case anybody wants to make recommendations- MUST be EF, must work on a full frame/35mm camera. Prefer a prime, and budget pretty much dictates a prime.
