Hi,
The first of the tests are "in" on Pentax Forums for the new HD DA 560mm F5.6 telephoto,tests have been run mounting the lens on a Pentax film camera so as to establish it's coverage "on the full frame format" The (scanned)results show that while the lens is designed for the APSc sensor, it "just" covers FF, but with a degree of vignetting.
Here is the link; http://www.pentaxforums.com/news/da-560m....html#more
A full test on APSc is soon to follow.
