So it appears there are still advances to be made, improvements yet to
come...

Ok, it's only a 5Mp sensor at this point, but if this design (which
makes me think, why haven't they done this before? (or have they? -
this isn't really my field)...) can be produced relatively cheaply and
for higher res sensors as well, it will put some good competitive
pressure back into the market.

I didn't see where it was cheap but that'd be great. I would get a Nikon
D30 Fx format even at 4MP if it was cheap & small.


I meant 5MP as stated. 6MP would be better.

"Conventionally, consumer digital video camcorders and digital still
cameras have been required to combine high resolution capable of
capturing every detail of the subject matter, and miniaturization
oriented to portability. In order to meet these needs, image sensor
development has focused on miniaturizing pixel size, while maintaining
imaging characteristics. However, in addition to these ongoing
requirements, in recent years demand for improved levels of minimum
subject illuminance and rapid image capture has also increased. This has
led to the requirement of image sensors with improved signal-to-noise
ratio and other features capable of realizing improved overall picture
quality."

It seems I've heard of back illuminated in astro & scientific work...

Yes, but have you heard of the F frame cat sensor? It can be found in any
adult cat, and because it has a tapetus lucidum has excellent night
vision (low light), also very good MP rating in bright light, the problem
is meowing which can distract from picture taking.


Meowing wouldn't bother me if the cat could produce a raw file g.

Of course, it will eat a raw fillet;-)
