This would tell me what lens has the best resolution/image quality. If this wouldn't be the case nobody would drag a 500mm 4.0 around to take bird photos. A 50mm would do the trick and cropping and blowing up the photo on the computer would do the rest. HOWEVER, nobody will argue that digiscoping will give you the best reach for your money! Results speak for themselves, and once more this was clearly demonstrated in this study. Still digiscoping has a few disadvantages and for those Nikon Canon etc. will not have to worry about the market for long focal length primes.Digiscoping with DSLRs, in comparison with the conventional P&S digiscoping, allows for even higher quality images mainly due to lower high ISO noise (faster shutter speeds). All this reminds me to look more seriously into options to attach my D80 to the Pentax scope .....Ulli</blockquote>
