Jan 06, 2014 06:42 | #1 I was interested in buying a Sigma 35mm 1.4 but changed my mind because of price and the good possibility of getting a lens with focus problems. So I purchased the Canon 35 f/2 IS instead. At first I thought the lens was soft until I noticed it was front focusing.

I looked at my photos and notice the subject was soft but something in the photos up closer was in focus. I then set batteries up in a line and focused on the middle. The middle was oof but the battery up close was in focus.
