I'm pretty new to photography (one year, more or less) and want to buy my first 50mm prime lens next month. I've been reading quite a few reviews and posts about 50mm lenses from Canon and Sigma, and was mainly considering getting the Canon 50/1.4, but then there's this focussing issue many folks talk about... I know it's not an expensive lens, but considering there is no AF microadjustment on my 60D, well, I'm not sure if it's worth buying it anymore. If I'm not lucky and my copy is not a very good one, well, will I be able to live with it? Any thoughts? Thanks!
