In a previous post I noted that the 20x on this Sony is more telephoto than the Canon XF105HD JoeyUnity originally inquired about. Which is true ...

I just want to add however that it is more telephoto NOT BECAUSE of the 20x power of the lens but because of the maximum focal length achieved (subject to imager size). It is possible to have a lens that has a higher multiplier power (for example Fujinon makes a 101x lens) that is actually less telephoto, a lower maximum focal length, than another lens with a lower multiplier power (or for example Fujinon's 87SUPER).

The point here is that the multiplier alone does not tell you what you need to know. It's important to know the minimum and maximum focal length, at what F stop the minimum and maximum focal lengths can be achieved and the imager size of the camera.

For video zoom lenses there are usually two numbers in its model number. The first number is the "power" or multiplier. The second number is the maximum wide focal length. To compute the maximum telephoto focal length multiply the "power" and the "maximum wide focal length" together.
