The Q is 12mp camera with a 5.6 crop factor. 100 x 5.6 so you'd have the AOV of a 560mm lens on 35mm using that lens with the Q. Which is super telephoto by any definition. You could also get the same effect by using that lens on a ff sensor with 72mp and cropping to 12mp from the center of the frame. (I know of no manufacture making a 72mp ff sensor so don't ask, I just multiplied in my head which is less sure than it used to be so if I'm wrong tough).

I don’t understand this. How would a 100mm macro on a Q be provide extreme 
telephoto capability? (Not doubting, just would like to know.)
