Excerpt: This is a great starter prime lens. Delivers amazing photos. Very impressive. If you are short on funds, don't consider this one over the 1.8. This is essentially the same lens and the differences aren't worth the bump in price.
Excerpt: I haven't used a prime lens in years. Due to the birth of my first grandson, I wanted a lens that would give me a shallow depth of field. This 50mm, f/1.4 fit the bill. I like the images I have shot. I will say that it tends to take a while to autofocus. At least longer than I think that it should. I am also disappointed that the lens is not image stabilized. Apparently Canon is "in the process" of upgrading and perhaps soon the new iteration will include IS.
Pros: Easy To Use, Great depth of field, Lightweight
Excerpt: I'm a bit torn about this lens. I've had it for about 2 years now, and when I first received it, it fast became one of my favorite lenses. It is extremely proficient in low light situations, and the depth of field that this lens can deliver is very impressive. However, I have found maintaining sharp focus between f 1.4 - f 5.0 is extremely challenging and the vast majority of my portrait photos taken at this aperture range are unacceptably soft.
Excerpt: I dont know but this is the second time i bought this lens. When the F at 1.4 the focus like error. Front and back focus error. You can not focus at the point you want. ....... Is there any one have the same issue with me. I tried to sale the old one and buy a new one. But it does not help. Same thing. At the f2.0 2.2 everything is good but at 1.4 can not focus at the point you want to.
