Went out to the nature center today to give the K20D a workout with my A400/5.6 and A2X-S converter. This combination wasn't really working with the K10D or the *istD. Because the wide open stop is f11, I had to go to at least ISO 800, even though I was working off the tripod. Too much noise. The same was true for handholding the A400/5.6 without the converter. One of the reasons I wanted the K20D was to be able to use this lens and lens/converter combo efficiently. Some preliminary samples follow. All were with High ISO noise reduction set to weak.
A4005.6 with AF540GFZ flash and Xtender, ISO 800, handheld: http://photo.net/photodb/photo?photo_id=7013146 I like this one. A4005.6 plus A2X-S converter with AF540GFZ flash and Xtender on tripod, ISO 1000, exposure at meter reading, f8 @ 1/200th: http://photo.net/photodb/photo?photo_id=7013166&size=lg. A4005.6 plus A2X-S converter with AF540GFZ flash and Xtender on tripod, ISO 1000, exposure at f8 @ 1/1250th (about 2 1/2 stops under, but flash is pumping up the exposure. I had to push the midrange brightness on this which increased the noise, but it's still acceptable, IMO: http://photo.net/photodb/photo?photo_id=7013168&size=lg In brief, due to reduced noise at high ISO, the new camera is giving me long-glass capability that I didn't have with any of the other Pentax digitals.
