Sorry for the delay in getting back to you. The G6 conversion is very easy, more easy than the guide on converting the g3. I was lazy in getting the correct thickness glass to replace the ir block filter, and used two pieces of microscope slide stacked on top of each other, which gave perfect auto focus so I didn't change it. If you have any more specific questions please feel free to ask and i will reply to you straight away.
Thanks submannz for your response.
I've modified succesfully my second hand G6 a couple of month ago!
Very cool images indeed...but I've some AF problems. In macro mode the AF works properly, but when I use the G6 in the normal situation I don't receive the AF beep confirmation, so I often have out of focus images.
Any suggestion for this issue? I have the IR filtrer directly on the sensor, could the problem depends on the IR filter tickness?
Thanks in advance for suggestions.
