Having destroyed my 50mm 1.8 before dropping it from a shelf 2m, I decided to buy another one after 1 year without lens "correct". To my surprise, even though the model number has not changed, the finish seems to have been improved and the focus ring has a much better feeling than my previous goal. Level shooting, have a large opening is particularly great for my 450D which does not rise high in the ISO and also for beautiful blur effects. The development is correct, not suitable for sports or things that move, but for 100 ... I did a lot of portraits with this goal, all are absolutely perfect, details to die once F4 (Photo studio flashes) I absolutely buy a third
