Finepix F10 Zoom ISO 1600?
 
http://www.dpreview.com/news/0502/05...inepixf10z.asp

I just read the above release on dpreview... does anyone else have any
additional details on this digicam? How can they achieve ISO 1600 on a
1/1.7" CCD? Seems a little early for April Fool's jokes.

From that link:
"The newly-designed 6.3 megapixel Super CCD sensor features Fujifilm's
trademark octagonal photodiodes, which act as more efficient light
receptors than traditional CCD structures."

The octagons pack tighter on the chip? The interpolation is better,
every third pixel in most all digicams is R,G or B & they have to borrow
from their neighbors to be given full color. The octagon has twice the
number of close neighbors to borrow from so ought to perform better. I
saw a good link explaining this the other day.

So then Fuji has reworked their "diamond shaped" sensor scam. Remember
all those bogus 6MP cameras that only had 3M physical sensors? By
rotating the grid 45 degrees, they can create a visual deception in
their specifications showing closer spaced sensors. It's not true.
Simple physics or a field test reveals the scam.

Light hitting the sensor has no quantum dimensions. Each sensor has a
lens over it. Whether the semiconductors are square, angled square,
round, triangular, or octagonal makes absolutely no difference. The
pixel count, resolving power, and the color neighbor count remain the
same.

Based on the quality of their previous cameras, I wouldn't expect much
of Fuji's ISO 1600. Expect severe noise filtering damage.
