After almost 2 years entry into digital photography with the EOS 450 + EF-S 18-55 I invested after some back + forth in the EF-S 15-85. The lens has really given me over the past 2 months a lot of joy. Compared to its predecessor: - Significantly improved sharpness (sharpening is now only minimally or not at all necessary) - More beautiful color illustration - Beautiful bokeh - Increased zoom range with better picture quality - Better feel and perceived quality Overall, the better picture quality makes considerably more fun. I have many images photographed with the new lens again, always with better results. I am excited about what is thus extract from an entry-level camera like the EOS 450. Incidentally travels with me, the tube does not automatically out, a lock so I do not miss. Clear, vignetting and distortion, I can say also, especially in smaller focal length and large aperture. Has been designed for, in my view and not as dramatic. Can also count out when needed. For me, the lens was a good investment, making it an absolute recommendation. 5 Stars!
