. . . the focal-length and sensor-size of a GoPro hero3 Silver?
We tried to stitch some test-shots but failed with finding both values.
Google didn´t enlighten us at all in that case . . . 
best and thanks in advance, Klaus

gopro 3 silver edition (11mp sensor):
1/2,5 Zoll Sensor
f 2.8 - 6 element aspherical lens
older gopro hd hero model had an:
approx. 5 x 4 mm CMOS-Chip (1/2,5-Zoll-Format)
the goprp hd hero 2 model (11mp seonsor) had an:
1/2,3-Zoll-Sensor
according to gopro 3 silver edition the camRaw modus does use the CMOS sensor best

ah - bingooo - found:
the gopro black edition does have this seonsor inside:
Sony has now released the IMX117CQT, a Diagonal 7.81 mm Type 1/2.3 approx. 12.40M-effective pixel, back-illuminated CMOS image sensor

silver edition does have a 11mp sensor - I assume its the same of the GoPro HD Hero 2

Hi Georg!
Thank you!
But i need the precise numbers of pixels and the precise dimensions of the sensor as well as the precise focal-length for designing a rig.
The informations one gets from GoPro are rather . . . . nebulous 
Guess i write a mail to the GoPro people.
best to you, Klaus
PS: Sony´s not an option.

Hi Klaus,
the Sony link: its the data for the black edition
Under http://goprouser.freeforums.org/hero3-b … 10016.html it is referenced. In debuglog you can see it:
1. [00000631] *================ Sensor Driver Rev Info ================* 2. [00000631] [IMX117] IMX117_Rev_20120815 3. [00000639] [IMX117] Sensor HW Reset 4.

[00000658] row_time: 10.8330 us, VB: 4604.0250 us, HB: 3.8333 us
according to wiki entry the GoPro 3 Silver Edition has the same sensor like the older HD Hero 2 its just smaller in case dimensions.
wiki: http://en.wikipedia.org/wiki/GoPro#HD_H … er_Edition
the HD Hero 2 Seonsor:
1/2,3 Zoll CMOS Sensor, ca. 11,04 mm Diagonale, 3840 x 2880 Pixel,
http://www.pennula.de/kameratechnik-gop … sional.htm
and according following source the 1/2.3 zoll CMOS Sensor the dimensions can be calculated to: 6,12mm (w) x 4,6mm (h) with 9mm focal (but this does not fit to the 11,04mm diagonal)

so best would be qualified answer from gopro (or dismantling one ;-))
