Reviews of cameras, lenses, tripods, heads and other accessories written by Ali_mohtashami

Canon EF 100-400mm f/4.5-5.6 L IS USM

Pros: Sharpness (only in FF), fast autofocus, Quick zoom, tripod ring

Cons: soft images in APS-C cameras, no weather sealing

Opinion: In my testing with a FF and an APS-C was very different in sharpness. In FF very sharp but in APS-C was very soft. In library test you can see this difference: ------- http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=113&Camera=736&Sample=0&FLI=0&API=0&LensComp=113&CameraComp=9&SampleComp=0&FLIComp=0&APIComp=0 ------------ This disparity exists for all apertures. Sharpness results in my 40D was very very bad.
