Come on, guys. I know you're trying to be helpful but it doesn't help to throw out guesses or inaccurate information.
Originally posted by hernandomdio enter the correct value of the focal length when turning on the camera so that the stabilizer works well
There is no value to enter. The camera will automatically read the focal length of all A, F, FA, FA-J, D-FA, and DA lenses. If the lens was a K- or M-series lens, then your advice would apply, but it's an FA lens.
Originally posted by zapp Try live view and you will realize what level sharpness is available. From there keep stabilizing etc...
This was addressed above. The K10D doesn't use Live View.
Originally posted by pentasonic49 If it is an FA lens, be sure to set the aperture ring to A, then the shake reduction will work properly.
The aperture ring has nothing to do with SR. The ring can be set to A, or any manual number and SR will still work.
