i have recently measure how wide angle my camera (C4040) can take on the widest focus length of 35mm, which i measured to be 42 degrees. i measure by putting 2 rulers in front of the lens, so that in my viewfinder can only barely see the edge of both the rulers.
however, i read a book about focal length and found that 35mm can take more than 42 degrees...( about 50+degrees, i forgot already)
at the nearest zoom, the angle is about 21 degrees, which is also not as i have read........
so my question is, how can we be confirm that C4040 is really 35mm to 105mm (i.e. 3x zoom) ..... can we judge by the angle of coverage?
