Actually, the reason lies in the manufacturing process. Pages 11-12 of an old Canon whitepaper detailing their full-frame sensor technology describes the economics of manufacturing image sensors of different sizes. Image sensors are semiconductor devices, like the CPU in a computer or the SoC in a smartphone or tablet, and are manufactured in batches by the ...

The 35mm film camera format has been with us since 1924 when the German Leica was introduced. The image size (format size) measures 24mm height by 36mm length. Now digital cameras are replacing film cameras. Most were built to house a digital imaging chip that has the same format size. These are called full frame cameras. As technology marches on it has ...

As I have said before: It's because the effect of any given focal length is a relation between focal length and focal plane - it's not literately a crop and 10mm lens doesn't have a specific fixed field of view. A 10mm lens is always a 10mm lens, however, what the field of view is with a 10mm focal length, depends entirely on the focal plane. So a 10mm ...

Because a 10 mm lens is a 10 mm lens. Crop factor has nothing to do with the real mm of a lens. Crop factor is the same as if you take your Photoshop and crop the center of a photo. Take a look at this answer: Do I use the crop factor in calculating aperture size and area? The crop factor equivalent is to give you "an idea" if you have being using a 35 ...

The crop factor does not affect the aperture. The aperture is given by the phisical construction of the lens. The focal length and the pupil. f = focal length D = Diameter of the pupil Fnumber(N) = f/D No other variable is there. If you phisically affect the focal length, for example using a teleconverter then you do need to make adjustments to the ...

Well yes, your effective field of view is the same as the FOV with an 896mm focal length lens on a 35mm sensor. However, a smaller sensor has a different magnification compared to a FF sensor at any given focal length - it doesn't crop an APS-C lens, but magnifies the focal length differently than a 35mm sensors does. The higher pixel pitch of most smaller ...

Yes, placing a teleconverter on a crop works exactly the same as on a full frame – you multiply the teleconversion factor by the lens focal length, and since it's on a crop, you factor in the 1.6x crop factor of a Canon APS-c to get an effective focal length of 896. Keep in mind that placing extenders on any lens will decrease its effective aperture. For ...

Well, the main thing is that crop factor doesn't really affect focal length. It just affects the field of view by making it narrower. So, what you really have is a 400x1.4x => 560mm lens combination on a crop body, which has the same FoV that an 896mm lens would have on a full frame body. So, unless you shoot full frame enough to translate focal lengths to ...

Yes many people do exactly what you suggest and end up with a field of view that is equivelent to an 896mm lens on a full frame camera.
