Some comments on the images shown before
My first pictures were blurred until I remember that basic rule on photography about distance and speed of the subject, focal length of the lens and speed of the camera.
Using a powerful zoom as the 60-250mm requires fast speed to avoid blurring. In order to avoid depth-of-field difficulties, small apertures (large f number) are welcome : the solution relies then on sensitivity. Pentax offers a unique mode for that purpose : the TAV mode.
First, select the ISO range you want to allow. On my K10D, noise starts at 800
, so I selected the 100-400 range.
Then, select the Pentax-exclusive TAV mode : you select the speed and the aperture through the front and rear dials, and the K10D automatically adjusts the sensitivity.
The display shows the three parameters : speed, aperture and sensitivity. Ditto on the view-finder. If one of the parameters blinks, you're out of range.
