Even a 500mm F4 will have trouble keeping up with an 80mm class scope when it is being used with a digicam of similar pixel count to get effective focal lengths of 1200-6000mm. Frankly, there are so many superb examples of digiscoped images available on the web and in print now that I am amazed some still criticize the method. BTW, not sure why you bring up DoF as it really is only an "problem" at distances under 30m where a typical digiscope kit does even better at isolating the subject. Having IS is really moot when you have shoot from a tripod, but as you know most new digicams have IS now too and with typically better stabilization than a dslr kit!  The beauty of digiscoping is first and foremost you have a dual use scope that allows the hobbist to both view and photograph subjects of interest. And unlike a dedicated photographer, the insane 1200-6000mm focal length allows one to standoff from even small birds to get the shot uncropped at full sensor resolution. No need to get in close by creeping on my belly in full camo kit, or rig a kayak "hide" to get out on the pond/lake/bay.  Still there are tradeoffs with every method and no one method is perfect for every scenario. Best to have a full range of kit and techniques to exploit the opportunities I say. cheers,Rick</blockquote>
