Took this tonight using the 45-200 at the longest end. Have read many complaints on various forums about this not being a very sharp lens at 200mm. This is from 10 vertical RAW files stitched in CS4 and brightened up in Nik Efex and of course re-sized for the web. I either got a very good sample or alot of users are don't know how to use a lens at the 400mm equivalent. A slightly larger version is here All sizes | River_Valley_1 | Flickr - Photo Sharing!
