Originally posted by Maggie Ever since I got my K10D I've been a little vary about the AF. Today I decided to test the AF using this test procedure. (snip)
It's very difficult to make fine distinctions, Maggie, because camera shake caused some fuzziness in each picture. The center point is not really crystal sharp in any image. However, disregarding this, the focus itself looked reasonably fine in the three or four images I looked at (the larger versions).
So, if these are typical of your images, it appears you need to address camera shake far more than focus. Go back to the basics of proper arm placement for holding the camera steady, holding your breath during the exposure, and pressing the shutter release button gently to avoid jerking the camera. In lower-light situations, use a strong (not cheap) tripod to keep the camera steady during longer exposures, or raise ISO to allow faster shutter speeds, or add light to the scene to increase shutter speeds, or a combination of these.
Of course, make sure the anti-shake feature of the K10D is turned on, but this is not a cure-all for weak camera technique. You still need to make a reasonable effort to hold the camera steady, especially during longer exposures. If that is just not possible, then you need to avoid longer exposures by somehow increasing the shutter speeds as described in the previous paragraph.
