Hey, Firstly I just want to inform that the type of shooting I do is a whole lot of people (Lifestyle, Portrait, and Wedding). So I'm going to add a 50mm lens to my line-up for my 5D Mark II and I was wondering if anyone can help me. Im looking at the Canon 1.4 and the 1.2. For anyone who does not know, the 1.2 is considerably more expensive than the 1.4 and I was wondering what I should do. Is it worth it to invest about $1,600 in the 1.2 or should I just go for the 1.4 which is going for about $400. Any input or help would be appreciated. THANKS!
