From my experience pixel per bird is near irrelevant since the quality of pixel varies. If all pixels were the same then compact cameras with tiny sensors and lots of megapixels (some have 15 mp+) would be the tops. Instead they are pretty poor compared to DSLRs. From my understanding more pixels usually means smaller pixels (other things being equal) and more noise therefore lots and lots of pixels in a smaller sensor is far from desirable.I don't know much about the 7D or how it compares with the 1D Mk IV but my guess is that the 1D is streets ahead in terms of picture quality. Theoretically the extra pixels of the 7D may mean you'll be able to crop more but the extra noise (primarily from the 7Ds smaller sensor) at the level of extreme crop will mean a poorer image. I'm not a big fan of teleconverters. Again at extreme crops the image looks less sharp. Not sure about the noise situation when using a converter.</blockquote>
