I have a 60D and am new to this but wanted to get a 50mm lens. The two I'm looking at are the f/1.4 or the f/2.5 Macro. I'm planning on using it for portraits but like the ability to use it up close as well. A lot of what I've seen says that the 2.5 is just a lot sharper throughout where the 1.4 is really in it's best form between like 2.8 and higher. I want something that I can use in lower light than the 15-135 kit lens. I would appreciate any insight in what's going to make me happier in the long run and is more versatile. Thanks
