have a sensor size that is smaller than 35mm film. This will effectively magnify the focal length of any lens by a factor (dependent on camera) but usually appx 1.5x e.g. a 50mm lens will become a 75mm lens on a Canon 40D
Screams No No No No No. The smaller sensor does not magnify the image, effectively or otherwise.
The smaller sensor has the same effect as cropping the centre section of an photo taken with a 35mm film camera. That centre section is exactly the same size whether digital or film camera is used. The cropped image has a narrower field of view, but I repeat is not magnified. Any magnification only takes place at the printing/viewing stage.
As you might guess, this is a subject that really winds me up.
