Focal Length and Handheld Photography
Minimum Shutter-speed= 1 / focal length
E.g.: 200mm lens needs at least a shutter-speed of 1/200.

Using a Vibration Reduction (VR / IS) lens allows 4 more stops
E.g.: 200mm lens needs at least a shutter-speed of 1/.......

Terminology: Vignetting
Vignetting means that there's a decreasing (=darker) illumination towards the image corners.
Vignetting problems can easily be recognized in plain colored area like the sky as shown the the
pictures below - the pictures in the 2nd row illustrate the effective illumination as it would be present
when shooting e.g. a white paper.
