Ariaeve.. What other gear do you have?
Other people will certainty agree about the glass sickness that undoubtedly has effected most everyone on this forum. If your just starting out, I recommend the 1.8 II .. and get prepared to spend elsewhere.. Yes the body is cheap, and its not the diameter of a soup can, but having owned both I can tell you I have contemplated selling my 1.4 to fund other glass and picking up another 1.8..
After all, is the 1.4 really worth 3x the price.. not to me.. I can only say that after owning both.
Hey, was just going through the thread again and I realized I never replied to this. So super sorry for the late reply but my gear hasn't grown since then however I did end up purchasing the 50 f1.4 (I tried out the the 1.8 II but found that the 50 f1.4 performed a lot better for me). I got some gorgeous shots during Christmas and the bokeh was dreamy. I currently only have the t5i + kit lense + 50 f1.4 and some filters. I'm thinking of purchasing a flash but been really busy lately so haven't had time to dabble back into photography yet .
