With earning extra money from work, I have thought about purchasing this lens, but I keep thinking if I should really purchase it. As you can see in my signature, I have the 50mm f/1.8D which I primarily use for portraits and low light situations. Besides the micro that the 60mm has, should I really invest the $300+ bucks on this lens or just save my money? You ladies and gentlemen are the one's that think sensibiliy for me when it comes to my money and wanting more glass. As a side note, I'm shooting a friend's wedding with a friend of mine next month. Would this lens really make a difference to what I already have in my bag now? As always, thanks in advance.
