rgibbons: Is the flat lens efficient at passing light? My camera lens with coatings can pass over 95% of the light. Do the flat lens antennae block some light, and are less efficient?.

Thanks for the link Prossi. Indeed narrow bandpass filter(s) effect. Also, all 3 wavelengths are in infrared. Hope it is only a temporary limitation in manufacturing technology.
My question would be what happens with the nano antennas when the temperature changes (thermal expansion/contraction)? Would the focal distance change? What about the wavelengths that are passed = color shift?

Coyote_Cody: Very doubtful !! Too large!!

1" is still quite small just bigger/better than 1/3" 2/3" etc, but a 4/3 or APS-C or 35mm will NOT be in a normal 'cell/mobile phone' likely EVER!

How would you fit it unless able to 'fold' light compactly and then place exactly on top of the sensor - yes ? Still physics and engineering !!
I guess I am one of few that do NOT believe in Harry Potter or Marvel Comics superHeros magic BS - that 'reality' 5H1T gets in the way !!

Science can SEEM magical, but unless you are a Texan, it is NOT magic or religion !! ;)

Very nice going Coyote_Cody. Maybe you heard of this "religious" companies: Texas Instruments, National Instrument, Dell, to just name a few. You should visit Texas sometime and see for yourself :-)

Well, think of it as a FF Rebel. Then it is a wonderful camera! If the price is too high and it does not sell well Canon will reduce it. If it sells well it means that the price was right.
By the way your current camera is still taking the same wonderful pictures as last week.
I own an "old" 7D and it still works 3 years after I purchases it. Go figure!
It seems that a lot of people suffer from the iPhone upgrade mania.
Repeat after me: " I do NOT need to change my camera every time Canon releases a new model"

Thank you for a good review but...
don't you think it is a little late? Summer vacations are winding down here in USA since schools starts in just a few days.
I needed this review back in June when I was looking for a replacement for the Canon D-10. Maybe it was for the better since the D-10 still works very well, so I saved some money.
