Testing a Second Canon EF 70-200mm f/2.8 L IS II USM Lens

ISO 12233 Chart results for a second lens copy have been added to the Canon EF 70-200mm f/2.8 L IS II USM Lens Review page. Select "Sample 2" in the ISO 12233 chart tool.
 
The second lens appears to be even sharper at f/2.8 at the 70mm end and slightly softer at f/2.8 at the long end compared to my first copy of this lens.
 
Vignetting results and a flare comparison test have also been added to the review. Vignetting performance appears mostly similar to the version 1 lens - slightly improved in the mid-range focal lengths. The flare comparison (posted by request and yet un-narrated - at bottom of the review page) shows another great advantage the new lens holds.
