unless you are using the very best lenses, they are the limiting factor.
next limit is technique. hand holding won't tax the sensor's resolution even
with top quality lenses unless you shoot quite a bit faster than the rule of
thumb limit of 1/focal-length shutter speed.

Yes, and there is a theoretical limit to how small you can make a sensor
element, too. It's quantum mechanics; a CCD/CMOS sensor element (and I
guess a grain on film, too) is essentially a device that counts photons
hitting an area, and there's a limit to how small you can make that area
and still catch enough photons to be able to distinguish between different
colour levels. I've read that the smallest sensors today are pretty close
to those limits, but I'm not sure if that information is actually correct.
