AF-360FGZ on K20D Slow Shutter Speed in Av Mode
While shooting with the external flash with a zoom lens in Av mode, the camera selects the shutter speed; this depends on the focal length of the lens. While shooting at a 55mm focal length, the camera selects a shutter speed of 1/60 (regardless of aperture). However, if I zoom out to a focal length of 18 or 20mm, the camera selects a shutter speed of only 1/30! This is too slow and often results in blurry photos. I have also trying using the external flash with shutter priority and a faster shutter speed, but this pushes the aperture down to minimum and thus I lose depth of field and sharpness. Has any one encountered this problem? Any suggestions appreciated.
