How to take sharp photos without (IS) Images Stabilizer or (VR) Vibration Reduction

Leave a Comment
There are many known technique to take sharp photos but common known methods is by using Tripod or with the help of the (IS)  Images Stabilizer in Canon or (VR) Vibration Reduction in Nikor in the lenses. But in some cases your lens is not equipped with IS or VR and most of the time you are not carrying a tripod and you don’t want to lose that shot.

A simple technique used that worked 95% of the time for me is multiplying the effective focal length of your lens against the crop factor of your camera.

Example:

Im using a Canon lens 17-40mm L (no Image Stabilizer) and with a Canon EOS 60d DSLR with a camera crop factor of 1.6 (see table above) so by getting the effective focal length of my lens e.g. 40mm (maximum focal length) X 1.6 (my camera crop factor) = 64, so my minimum shutter speed will be 1/64s.

The formula is Focal length of your lens X crop factor of your camera = The minimum shutter speed you will use.  Try it!!!!
