I know there are so many posts on what to choose for a better lens for your camera but I thought maybe you could help me if I told you what kind of photos I mostly take. Background...I have a Canon t5i with an 18-55mm IS kit lens. I take portrait photos of my dogs, sometimes on a setup I have on a table and sometimes of them just standing on the floor. I am usually about 6' from them no matter. I shoot in Av mode with an external speedlight. My desire is to get the clearest, sharpest photo I can get altho I think that also comes with experience as I go along. I am also interested in the pet portraits having a blurred background. I am interested, at this point, in stepping up to a mid range lens, not yet ready for the pro prices. I have been reading reviews on the 85mm f/1.8 and the 50mm f/1.4, just cant figure out if either are right for my needs or if I'm off base and something else is better for my first step up. I am in a very rural area and dont have a camera shop within 100 miles so have to order and I favor my Amazon Prime method if that makes any difference. Thank you for any advice you might have.
