I had to remove the dust buildup behind the
low-pass filter because there was one speck I couldn't stand. An authorised Panasonic Lumix service centre is pretty non-existent here, at least in the North Island so I had to do it myself. I got tempted to remove the
low-pass filter but the magenta cast was strong, of course, because the filter is blueish in colour. The images were
GX85 sharp, though.
About 6 or 7 years ago,
low-pass filters were pretty common in cameras and, while camera centres offer the usual two-wipe cleaning service, they were just wiping of the relatively tough low-pass filter cover, not the sensor.
Canon 5D II sensor assemblies, though, are easy for dust to build up and I know plenty of shops doing thorough cleaning behind the
low-pass filter.
