Here is a photo with the K-5, PF-CA35 and PF-80ED. The rig was mounted on a tripod and the shutter triggered with the Pentax Remote Control F. The file properties as shown in Microsoft Windows Explorer are: shutter speed: 1/90s, ISO: 800, no exposure compensation, sharpness: hard, contrast: hard, saturation: normal, and, of course, a fixed aperture of f12.5. I'm not sure whether I had any in-camera noise reduction turned on. I have resized it to 1204 x 798 using Microsoft Office Picture Manager, but have not otherwise edited it (I am offshore, so I don't have enough bandwidth for large attachments). The EXIF information on the uploaded photo may been stripped off by Picture Manager.
Regarding soft, I mean that the subjects in the images are not as sharp as with my FA* 400mm f5.6, i.e., fine details are not as apparent with the scope as with the lens. I don't know whether that falls under the definition of focus or sharpness.
I recall seeing a few pictures somewhere in Pentaxforums taken with the PF-CA35 and one or some of the Pentax spotting scopes. Unfortunately, there is no sub-form on Pentaxforums specifically for Pentax sport optics. Try searching the keyword "digiscoping".
Oh, and yes, the PF-65ED with the PF-CA35 has a focal length of 750mm with an aperture of f12.
