Back to basic in Photography - Shutter speed

Something i read sometime ago which is very useful for people who just got into photography. The one most common question is why my shots are blur? wat shutter speed to use?

It's pretty simple, basic rules is 1/x shutter speed, in which x = focal length.

Example:

u using a 18-55mm lens, when shooting at 55mm you will need 1/55 s. However, due to the crop factor in digital body, we need to multiply with the crop factor. so instead of 1/55 s it becomes 1/88 s which is around 1/80s.

A simple chart for you all

Focal Length (mm) Effective Focal length  (mm) Shutter  (s)
 18  28.8  1/30
 24  38.4  1/40
 28  44.8  1/50
 50  80  1/80
 55  88  1/80
 70  112  1/120
 90  144  1/160
 100  160  1/160
 200  320  1/320
 300  480  1/500
