Review on Canon EF 50mm f/1.4 USM lens, black by Micha Borkowski ᠌

It is not worth purchasing this lens. Of fact, the quality of the 50mm f1.8 is even worse than that of the 35mm f1.4, but its price is significantly more agreeable and its design is more robust; if you get a decent copy, you will be satisfied. There is a problem to using a 50 f/1.4 lens, and that is that if you press on the front retractable part of the lens by accident, or at least lightly impact it, the guide bends there. When this happens, the focus begins to play around, and autofocus accuracy is lost (although it was never that accurate in the Canon system anyway). When I tested it at 1.8, the entire bottom portion of the picture was blurry on it (or the top portion, depending on where the focus was set). As a result, I went out and purchased a 1.4 because I erroneously believed that because it was more expensive, it must be of higher quality. It is strongly recommended that you pick a solid instance of 1.8 rather than tinkering with 1.4 in any way. f1.4 it most certainly does not have a functional hole, and also, autofocus never hits it.
