Terrible lens. Not worth the money at all. I really wish I never bought it. Most reviews I have seen talk about the amazing image quality for such a cheap lens but I never got that feeling from it. I was excited to get my first fast prime and since "everyone should have a 50mm" I figured why not go for the 50mm f/1.8 II that everyone likes so much... I had my camera bag unzipped and grabbed it out of my car (OOPS!!) My XSi and 50mm went clunking to the ground, all of a 2ft drop. There lay my brand new lens on its second day of ownership, mounted to the camera and the front half elsewhere on the concrete. Forutunately it pushed back together and still worked just fine.
Overall, I was never impressed with the lens. I had some fun with it, but ended up giving it to a friend because I really didn't like it. It had its moments, but not enough to justify. If I could do it all over again, I would never have wasted money on it. Now-a-days with the 40mm pancake in Canon's line up I think the 50mm f/1.8 II should be retired or heavily updated.
Wide open performance was not very good on my copy. I had stopped down to f/4 and still didn't get a sharp picture on my XSi. It may have been something with AF missing focus, but I tried the same scene standing in place from f/1.8, f/2.8, and f/4. I didn't have any shots I was impressed with during that initial testing period. I did, however, get some shots I was happy with. The tulip in the first picture was one of the first pictures I took with the lens. It was taken about as close as I could get. I don't remeber any of the settings but it was taken with an XSi.
These two shots were me testing/playing with the difference between f/1.8 and something with more DOF. This is the point when I learned about shallow DOF and subject separation. Notice the pentagon bokeh balls in the headlights of the 3rd image. Focus was on the tulip and in the 2nd picture, doesn't look very sharp to me.
