I wonder if anyone else has tried an A-400 on a K-1

K-1 and SMC Pentax A-400.
3200 ISO, ƒ8 or 6.3.

I was working pretty close to minimum focussing distance at about 275mm K-3 mm, and small fast birds with MF is not treat, but everything is possible.

Two nicely detailed shots.

Thanks eaglem....although the images were more proof of concept than anything else.

Excellent focus on these, what do you think about contrast in your PoC though?

On that day... shooting at the limits of the camera, the images are a bit flat.... but, 3200 ISO and ƒ8, you've lost a lot of dynamic range, even if the noise is still acceptable..

Next day with better light and 800 ISO and F 11... much more contrasty results....









The main issue is 600 FF is sort of a minimum for birding. The 400 on a K-1 is not much better than a DA*60-250 on APS-c.Believe it or not, I bought this lens from a man who used it as his long lens for weddings on film. On one of these I actually had to turn the contrast down when using my standard preset.

Actually nice shots.
