Re: NX20: how to remove back cover or service manual

Problem solved thanks to the NX10 service manual.

The soft part of the viewfinder can slide upwards to make 2 screws visible.

After that, no further surprises and the image sensor module can be accessed eaysily to remove the infrared filter

Infrared filter with integrated piezo-electric module for cleaning the lens

Picture with Hoya filter that removes all wavelenghts below 720 nm.

I have ordered a filter that cuts all wavelengths below 1000 nm. Above 1000 nm most pigments are transparent except for carbon black. Hopefully it will be possible with the modified NX20 to study carbon black underdrawings in paintings.
