Can you imagine a super-tele-lens you can use hand-held? It has been done, but it's hard (for traditional cameras these lenses weigh several kilos), and you need dang good light because you need shutter speeds like 1/1000th of a second. (A tele magnifies not just the subject, but also movement/vibrations.)
Now can you imagine a supertele/camera combination with such effective stabilization (Stabilization tech in the lens actually cooperates with stabilization tech in the camera.) that you can use it hand-held down to 1/10th of a second!? This reviewer says we have one now. If others generally can achieve the same with it, or anywhere close, this is pretty revolutionary. There is no lack of areas where you need a long tele, but a tripod is not practical.
