Second Canon EF 100-400mm L IS II USM Lens Tested, Vignetting and Distortion Results Added

Image quality results from a second lens (presented as Sample 1) have been added to the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens page.

Again, I think that you are going to like what you see. Both lenses perform superbly and the two copies of this lens perform nearly identically. The second lens is very slightly sharper in the corners over part of the focal length range (look at the 200mm and 400mm samples to see this).

Here is a preloaded comparison between the two lenses with the second lens presented as the default/left lens.

Distortion and vignetting test results are also now available for this lens.

B&H has significant quantities of the Canon EF 100-400mm L IS II USM Lens arriving regularly. Demand has been very high.
