Re: GF6 for infra-red conversion?

Not sure I'd do that myself, as you then need filters for all your lenses if they're different thread sizes, but it does give a very flexible range of options on the same body.
My model is a full spectrum converted one, and I really think anything else for mirrorless cameras is limiting the options needlessly. If it's done properly the hot mirror will be replaced with quartz (clear glass gives 2 spectrum as it blocks UV). Leaving the filter off completely affects the focusing. I tried that on the old compact camera I converted myself - which remains a close-up only camera till I do it again...

FWIW You don't need filters for all your lenses - stepping rings prevent that. In addition you can often simply hold a filter in front of the lens too. That's what I did today while testing a series of 30+ lighting gels, and it's worked well with lenses that don't have any filter threads like the 9mm BCL.
