I believe a smaller sensor gives a 'cropped' effect so that a scene viewed from a full frame camera will have only a 'cropped' portion photographed by a smaller sensor camera located at the same distance from the subject.
Is that right?
It seems simple. The large sensor at any range subtends an angle at the subject and we can draw a cone. A smaller sensor fitting in that cone can only touch the edges if it is moved in to the subject.
So at any distance you 'see' more with the larger sensor than the smaller.
They why is the situation reversed with the two cameras I have here: A canon powershot A520 with a 5.8 - 23.2mm lens and a Canon EOS 350D with an EF 35-80mm lens ?
The Powershot roughly seeming to have a FOV about 4 x that of the EOS?
Is it something to do with the EF lens or have I just everything wrong, seriously wrong?
