Help choosing the 50mm f1.2l USM ~or~ 85mm f1.2l II USM

You didn't say what you are shooting with now but I assume you have something like the 24-105 zoom. They are both great lenses. It's all about what you shoot so go back and look at your images and pick out the ones you like the best. Look at the EXIF data to see what the focal length was and then go from there. If the majority are closer to 50 then get the 50; 85 then get the 85.
