Canon 70-200mm f/2.8L IS II at 135mm and 200mm
Just added to my review of the Canon 70-200mm f/2.8L IS II in DAP is are two new pages, one showing performance at 142mm, and the other showing performance at 200mm.
The examples are with sample #6, the best of six samples I tested, and the results can be taken as representative of the best possible performance for the 70-200/2.8L IS II.
The 142mm page also includes full-resolution downloads for f2.8, f/4, f/5.6, f/8.
At about $2499, the Canon 70-200mm f/2.8L IS II is hardly a casual purchase, but it banishes the haze at f/2.8 of the original model, which might be reason enough to upgrade for anyone who regularly shoots it wide open.
