successful removed bayer matrix filter of NEX 5

Description

The 2nd trial of removing the bayer matrix filter worked. :-)
1) removed the cover glas, glas broken, but no violation on sensor
2) protected the golden wire with glue
3) removed bayer matrix filter with soft wooden pencil

There are still some bayer matrix filter remaining on the sensor. (good to see at revision F)
I will carefully remove it full in the center area and the planned area.

Currently I can use 84% of the APS-C sensor size. 11,76 Mpixel out of 14,03 Mpixel
I will keep a border not removing the filter.

Check comparison with my 135mm Samy stopped down to f 4 to have sharp results.
All pictures are made with 1/50 sec and 800 ASA.
see the improvement in S/N with debayerd sensor.

I have measured the sensitivity with bayer matrix and removed:

- RGB becomes 200% sensitivity (300% x 0,7)
every pixel gets full spectrum instead of one color only.
compare B (debayered) and C (modded)

- HA becomes 300% sensitivity (400% x 0,7)
4 pixels instead of 1 pixel can be used for HA
compare D (debayered) and E (modded)

The loss of mirco lenses costs 30%of light input, or lets say the gain is now 0.7

.....I will start with AP- tests with my SAMY 135mm @f2 with 35nm HA filter....
