Which is a very good thing for in-body anti-shake systems.

Also a good thing for battery life; that nice large battery compartment
and half the sensor size is about root 2 of the power requirements.
This is always going to help.

Just before Hitler's War started, somebody asked asked the fellow
running the Cunard line what it was like to have the largest, fastest
liners in service in the world.  His reply was that they were the
smallest, slowest ships that would do the job he needed them to do.

Theoretical image quality does me no good; the best image quality I can
_use_ is the best image quality I can print, and that's constrained by
the printer and will be for quite a while, and even if it wasn't,
there's some decent evidence that people just can't _see_ better than
600 dpi or so.

Never mind how much stuff is being done for the web, or the trajectory
of increase for content actively displayed; the effective image quality
limit is in the printer tech, not the camera tech.  So long as that's
true, the requirement is for a camera that *keeps* that true, not for
the best theoretically achievable IQ.
