Hi, may i give you a little tip after succesfull debayering 15+ nikon d600/d610 cameras?
Never use heat on the glass, you may solder out the chip or overheat the board. The glass has to be removed mechanically.
Never use [removed word] like wooden sticks or polisher paste or something like that.. you will get broken lines and never get rid of dust and leftovers. Also dont cover the golden wires with an epoxy, they will be teared as temperature rise.
Debayering is a CHEMICAL process, with right chemicals your sensor will be mirrolike.
I add a pic of bayer filter curls up into tube to illustrate how it works. Also i can make debayered imx128 sensor (d600, d610, a7, a7-2) for a reasonable price. In nearest future i will try a7r and d800, i suppose the process will be the same.
And a debayered full frame is of course better camera than someting like asi1600mm, it is just 4 times bigger with bigger pixels and strong processing.
