80 MP medium format backs
I've been reading with great interest the field report of the new super high resolution Phase One medium format back done by Michael over at Luminous Landscape. This monster gives 80MP real resolution and Michael thinks it is equivalent to drum-scanned 8x10" film. This would be extraordinary if true. Looking at the 1:1 crop and counting pixels, the resolution appears to be similar to or slightly better than what I get stitching (see here, here or here) multiple images from my crop DSLR using my very cheapest kit lens. Of course getting that kind of quality in a single shot is far more convenient than my el cheapo solution as you can compose the shot far better. When I compose, I usually make a guide shot with an equivalent wider angle lens to the final stitched image's viewing angle. This works to a degree but is not perfect. I cannot exactly compose this way. My stitching solution also has trouble with very long lenses as the rotation between frames becomes very small so it works best for wide angles. All in all the new medium format backs are very interesting products. Of course I can't really afford such a machine (44k$ for just this new back, no body and lenses included!) which is probably why I don't get these cameras sent to me by Phase One or any of the other makers for testing. I'd be happy to put one through its paces though! Michael mentions stitching multiple shots from this camera. That concept just blows my mind.
