Excerpt: bought it to photograph some paintings. big mistake. should have read the reviews on lens tests. the sharpness at f/5.6 to f/11 is excellent, no doubt. but, the barrel distortion is very, very high! i have to use photoshop to correct every image for straight lines and sides. it's really bad! should have bought the 85mm f/1.8 as it's much less distortion, or the sigma 50mm hsm which has no noticeable distortion. focus is slow and noisy on the ef50 too.
Excerpt: It is early days for me with this lens.I love the 50mm prime but regret slightly not having the money for a f/1.2 as the 1.4 is found wanting in lower light conditions. In good light and with a flash for portraits results are excellent. It is a good lens for the price but not a great lens.
Excerpt: I had to return the first copy of this lens after a month. The focus ring locked up. The second copy works fine. B&H was gracious and let me exchange it even after the thirty time period was up since I was out of town on a shoot. Pretty bokeh, very fast. But the construction feels flimsy to me, after getting used to the build quality of the L series lenses. As a throw-away lens, it's not bad. And the price is right. But I'd be careful with it in an outdoor setting.
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.
