Fuji new high ISO values in SuperCCD HR is fake !!!

[Frmg]

Hey users please look at this important detail ...

Fuji Finepix F10 ISO equivalence with Casio Exilim EX-Z750:

When light is >98% CRI is the two cases we have:

Fuji FinePix F10:
EXIF information = ISO 400, 1/345 sec, F4.3

Casio Exilim EX-Z750:
EXIF Information = ISO 400, 1/400 sec, F5.6

Look at the exposure times and the aperture values.

Ok lets go,

Fuji FinePix F10:

Focal range: 35mm
Aperture: F/4.3

So ... 35mm / F4.3 = 8.1395

Area = Pi x r^2

r= 8.1395 / 2 = 4.0697

So ... 3,1416 x 4.0697^2 = 52.0326 (mm2)

Casio Exilim EX-Z750:

Focal range: 35mm
Aperture: F/5.6

So ... 35mm / F5.6 = 6.25

Area = Pi x r^2

r= 6.25 / 2 = 3.125

So ... 3,1416 x 3.125^2 = 30.6796 (mm2)

How you can see the Fuji F10 need almost double of light when compared to Casio Exilim EX-Z750 for ISO400 !!!

For the equal ISO sensibility Fuji Finepix F10 need exposure time at ...

52.0326 . (400/30.6796) = 678 (exposure 1/678)

How the exposure of Fuji Finepix F10 is 1/345 we have ...

345. (400/678) = 203,43 (ISO200)

Is this !!! The ISO400 in Fuji Finepix F10 have the sensibilty of ISO200 in Casio Exilim EX-Z750 so the high ISO settings in Fuji new sensor are absolutly fake !!!

I think that is very important to many users in the world.
