Moose - Thanks for all your tips here. I am new to this forum and am interested in purchasing a new lens to take close up photos of my toddler and baby. I have read through a lot of your responses and was wondering if you could help me with the difference between the Canon EF 85 mm f/1.8 USM vs the EF 50 mm f/1.4 USM for close-ups with background blurring. It seems the price is very similar on Amazon and I am trying to decide which is the better lens to buy. Thanks!
