Pentax K-3 + Nikon 800mm f/5.6 (2 imgs)

Hi folks,

My friend brought back my Nikon 800mm f/5.6 lens so I gave it a try using Catch-in-Focusing (CIF) on the Pentax K-3. The camera wouldn't fire using CIF with the lens set to f/8 so I had to shoot wide open at f/5.6. I used a Nikon-PK glassless adapter. I should have also used an extension tube because the focus distance was near minimum at about 28 feet and I had to crop these images more than I like. To shoot at f/8 or f/11 aperture I will need to set the camera to MF and use an extended length wired remote and just trigger the camera myself when the hummer lands.

These are not bad at f/5.6 IMO.
