This is an ultra-wide zoom lens which has very good optical quality and good low-light performance. In spite of being a wide angle lens, accurate focussing at large aperatures along with careful hyper focussing at small aperatures are critical to successful imaging with this lens.

These are the same images that are presented in my main galleries but here they are sorted into separate galleries according to lens. This may assist those that are shopping for a particular lens and wish to view some sample images taken with the lens on a 1.3 crop factor (Canon 1D) and full frame (Canon 1DsMkII). _3.25_
