Hi there,



I ended up with a new Canon 15-85mm that is slightly decentered at 85mm wide open. Other focal lengths seem OK to me.



Below are two 100% crops taken with a 10 megapixel camera. The pictures show the 4 corners copied closer together for better comparison.

The photos are representative of the large number of shots I took. test1.jpg was composed of 4 shots, first focused at infinity with center AF and then recomposed each time to put the tower into one corner. The test chart setup (test2.jpg) was perpendicular and I used AF at the center.



I went through 3 copies of the lens and they were all the same (more or less).



Since the lens test on this site also mentions decentering I would like to ask: is this amount of decentering inevitable for this lens? Would you keep it or hunt for a better copy?



Thanks



Tom
