10 out of 10 points and recommendedExcellent optical quality, light, lets in a lot of light, simple to use, great bokeh and depth of fieldNothing!
I bought this lens, mainly because I just bought a new camera, with a 135mm 2.8 soft focus lens (for portraits) but decided the minimum focus was just too far away - researching the 50mm 1.8, I decided to try it out and I loved it! In fact, it's better than the 135mm 2.8, in so many different ways. It lets in a lot of light with the 1.8 max aperture, it can focus easily to close subjects, it has an AMAZING optical quality for such a little thing. The best thing is the price, I can't believe how cheap it is! I definitely prefer prime lenses to zooms now, due to the sharpness. This will be my portrait lens AND landscape, macro, standard etc etc.reviewed November 13th, 2010 (purchased for $150)
Thank you Canon for making such a perfect lens. My next buy will surely be the 50mm 1.4 (although I have heard it isn't much of an upgrade).
