lol the 50mm seems a real good deal - I'm usually into you get what you pay for, so I'll go with it and get one, I just reckoned that I needed a big zoom to blur the backs out like this:
or this is the type of shot Im getting from my 80mm at f5.6 - but I guess its cuase my lens wont go faster (the bloke that took this was using a 150mm)
