An extra few thoughts...
I haven't seen anything released from Sony with HD video, but it's  
hard to figure out who's making what right now, and I may have missed  
it.

This is all pure conjecture on my behalf and I'm only speculating, but  
it seems like the K7 is using it's "full sensor" (well virtually  
anyway) to resample with the 1536x1024HD, as the numbers equal out to  
exactly 1.5:1 ratio, which happens to match the chip size exactly. So  
maybe there's a better image in that? Again, not sure, but it sounds  
like a better way of doing the bilinear interpolation, if they  
actually are using a bilinear interpolation method and not a .

The Pentax K7 will also take a slew of lenses - especially anything  
that's compatible with M42 mount. I can't remember if anyone ever made  
it (Raf, maybe?), but if you have an OCT18 or OCT19 to M42 adapter,  
then this one may be for you. Also, even though the camera shoots a  
weird 1536x1024, if you slapped an anamorphic lens on the front of it,  
then you'd have a 3:1 stretch that you could play with (in other  
words: "widescreen").

Okay - I now have to run to teach my "Intro to Film" class...
