I need help deciding if I should sell my canon 50mm f/1.8 and buy a used canon 50mm f/1.4. The 1.4 lens is in excellent condition and she's only asking for $200 USD. Should I go for it? Is it much better than the 1.8 version? I really like the idea of the extra aperture, but I've read it isn't that sharp wide open...
Thanks for you help
