:thinking:Hi,
Could somebody give me the equivelent lens ranges please, SLR Film lens to Digital.
ex. 18 - 135 Digital = 28 - 200 SLR Film camera?
 
Multiply by the crop factor of your camera.

e.g.

For Canon 1.6 crop, a 50mm lens = 1.6 x 50 = 80mm equivalent
For Nikon 1.5 crop, 50mm lens = 1.5 x 50 = 75mm equivalent
For m4/3 2x crop, a 50mm lens = 2 x 50 = 100mm equivalent
 
It all depends on the size of the sensor in the camera. If it is full frame sensor, then this equates to a 35mm film frame, so the lens focal lengths are the same. If the sensor is smaller then the camera enlarges the image to fill the frame using something that is known as crop-factor. In a Canon the sensor crop factor is 1.6, so a 100mm lens would equate to a 160mm full frame (35mm) lens. Nikon sensor size gives a crop factor of 1.5.
