I believe the added weight of the longer lenses puts the gimbal out of balance, which can only be compensated with more weight...argh. Perhaps I'm wrong??
Well I have a thought on that which I can't verify anywhere:
Small light sensors only need small light zoom lenses.
Big light sensors, like in the X5 camera, need prettig big and heavy zoom lenses.
Here it comes: why doesn't anybody make make a converter ring to adapt a small light weight (power) zoom lens to a camera with a large light sensor. Then you will have to crop the image a lot to match the small lens, but it will be no worse than starting out with a small sensor and lens camera anyway. And you will have the big advantage of optical zoom, which is by far better than digital zoom (for inspection purposes).
So is it possible to adapt a small 30x zoom lens to a X5 camera and crop the image?
