Focal Length Multiplier and Crop Factor
Whether a camera lens is seen as wide-angle or tele is dependent on its Angle of View (AoV); for a particular image size AoV is dependent on focal length.
Focal Length Multiplier
The Focal Length Multiplier is a figure to apply to 35mm lenses to calculate their true focal length on digital cameras that do not have full frame sensors.
Focal Length ...
focal length multiplier noun
a multiplicative factor that relates the focal length of a camera to the focal length of a 35mm camera that produces the same field of view
HFOV noun
horizontal field of view, usually expressed in degrees ...
Focal Length Multiplier
If you use digital SLRs (dSLRs) that use lenses made for 35mm film cameras, you need to be aware that the focal lengths expressed on the lenses must be multiplied by a factor.
Focal Length Multiplier - You can attach lenses made for 35mm cameras to some SLR digital cameras, and this will result in increasing distance from the lens to the film or multiply it.
Focal length multiplier
Uses anybody on a digital camera an objective, which originally.
Flash duration
The camera's flash synchronisation ensures the flash is emitted while the shutter is open.
What is a focal length multiplier (or cropping factor) for digital and APS cameras?
35mm film has an image area of 24mm by 36mm. These are the exact dimensions of the area on the film to which an image is recorded.
Full frame sensor, no field of view crop / focal length multiplier

Given a focal length multiplier of 1.6, that makes a 44.8-112 zoom. Unfortunately the total cost would come in at over $3000.
The Olympus E-520 uses a Four Thirds format sensor, which means that the aspect ratio is 4:3 (rather than the more usual 3:2 of other DSLRs) and the sensor is physically smaller, resulting in a "digital focal length multiplier" of 2x rather than the ...
The effective focal length multiplier for most sub 35mm sized sensor DSLR cameras ranges from 1.3 to 1.7 depending on camera model.
The impact of sensor size on field of view is referred to as the "crop factor" or "focal length multiplier", which is a factor by which a lens focal length can be multiplied to give the full-frame-equivalent focal length for a lens.

The printed pictures still come out the same size, but there's something sized differently in how they get shot. We call it the "crop factor" or "focal length multiplier," and it's the topic of this week's PhotoTip article.
