I don't know that you'd find an official description anywhere but I
think it's fairly clear that, just like Canon, single digit bodies are
professional or pro-sumer grade, double digit bodies are pro-sumer grade
and triple digit bodies are consumer grade. Nikon had seemingly been
following a similar numbering system but has recently announced bodies
with model numbers that don't seem to fit the pattern.
But I don't think the model numbering system has anything to do with
image quality. Rather, it's build quality and features. An inexpensive
body (like the E-300) might have a mirror arrangement instead of a
pentaprism. A more expensive body might have a pentaprism but it might
be small. A pro body might have a much larger pentaprism and better
viewfinder optics giving a larger and brighter view. A consumer body is
likely reinforced plastic whereas the pro body probably has a
lightweight metal alloy subframe with plastic coatings or cover panels.
Other differences can be found in the electronics. A consumer body
might have a image single processor. A pro body might have 4 processors
each handling different parts of the image in parallel for faster
shooting speeds. Finally, image quality will change with the technology
and not so much the model numbering scheme. I've never done the
comparison but I suspect an E-620 (5 years later) produces a better and
less noisy image than an E-1. But you can probably take an E-1 into the
Kalahari desert and expect it to survive the trip.
