I bought my Nikon 17-55 a few weeks ago and have only just started using it properly. I got a bit of a shock when looking at a 17mm image, the edges dont seem very well defined, rather "smudged"
So, I took some more with the Nikon and them some comparisons with my Tamron 17-50. The Tamron is far sharper at the edges at 17mm. Towards 50mm, the Nikon takes the lead in quality ( phew!) again, but I was concerned with the IQ at 17mm.
Is this to be expected or do I have a dodgy lens?
Heres some comparison shots, full sizes available if you click on the images. All Jpegs straight out of the camera
