The truth is that I never had a camera with interchangeable lens.
And so I do not hold well all the theory about it.
I will agree that there is some analogy involved between the size of the sensor and the lens type.
Example the small pocket cameras with fisheye lens.
In my case, My Olympus came with Sony sensor 2Mp, and a amazing fixed Canon lens system,
with gyroscopic image stabilization, and lots of power at true 10X zoom, plus bright and all.
But all those glass like sixteen internal elements , forces you to move back in close range , or to use wide angle add on converters,
so to equalize the loss in wide range, that the telephoto lens takes away.
I have an major difficulty to use the HD1010 ( also 10X ) with out tripod ,
my Olympus with the stabilizer its so much friendlier to use ..
And I do not make plans to stop drinking strong coffee either.
But there is no way to sell the HD1010 , its has so amazing image quality,
balanced colors , almost fast enough auto focus.
I had download the teardown of the U1272 at 720P quality,
and watched it on my 32" HD 1080P TV ..
It was so great , like to was next to Dave ..
He has wacky eyes .. don you agree ?
