Canon EF 400mm f/2.8 L IS II USM Lens ISO 12233 Crops

ISO 12233 crops from two review lenses have been added to the Canon EF 400mm f/2.8 L IS II USM Lens Review page.
 
As expected and similar to what was seen in the Canon EF 400mm f/2.8 L IS USM Lens Review, the results from this lens are impressive. Less impressive is the much-hyped-by-Canon with-extender-III image quality performance. My Canon EF 400mm f/2.8 L IS USM version I Lens performed at least as well as either of my Canon EF 400mm f/2.8 L IS II USM Lens lenses with extenders mounted.
 
Lens specifications and measurements are also available for the new 400 II. The lighter weight of this lens over the previous model is very noticeable - and very welcomed.
