I have been a Canon user for many years, untill recently when I bought a 50D and was utterly disapointed with the IQ, the first one I had rear focused on many different lenses and the second, the noise levels were unacceptable! Needless to say it went back to the shop and I made the gut wrenching decision to move to Nikon and chose the D5000. WOW!!!!!!! The image quality on this camera is just superb!!! With the canon if you wanted to under expose a shot you would have an increased and unacceptable noise level even at ISO100! Also with the Canon (50D, so called semi pro!) if you had to boost the exposure in ACR, with it you would get a massive increase in noise. The Nikon, well, what can I… Read more
I have had this lens on 2 Camera bodies, the first being the 450D and the current being the 50D. This lens is superb on the 450D, its sharp at 2.8 and superb at F4 upward to around F11. The only thing is, on my 50D it tends to rear focus by about 2" or so! But not every time so I am not able to use the 50D's focus adjustment! Its a real shame that this happens, it may just be my combi that doesnt get on? I use a Tamron 17-55mm F2.8 (non VC) and have no issues with that one. Because of this issue I have decided to sell this lens which is a big dissapointment to me as it is a superb lens overall with amazing IQ, for the price you will not beat it.
I have always owned Canon DSLR'S and the 50D is my latest. In short, this camera is superb. Its lightning fast in every way, solid build quality adds to the professional feel, and noise at high iso is great. The only thing about this camera is that it is rather unforgiving, what I mean is in order to get the cleanest images and make use of the high iso, your exposure needs to be spot on, if you under expose then noise WILL become apparent, but get it right, and the image will be superb. I find that mine, when coupled with my Tamron lenses, tends to under expose by about 1stop in low light conditions (indoors etc) but dial in +1ec and all is great! The other thing to watch is due to the… Read more
