So I've outgrown my kit lens (still having fun with my zoom tho). I"m looking for a good prime. I would do general stuff with it, but I like taking candid and/or portraits. I would like something that does well with low light. I had a 35mm with my Nikon that did that well. I'm reading the 50 f/1.8 is cheaply built, might look at the f/1.4 or even the 40mm pancake or even an 85mm?
