Thanks for calling in. Yeah, I was aware of how the filters worked. The Minox is a mess to get filters on, there is no filter thread, you can get one if you buy the Minox UV filter, in which case you want a 32mm thread. I had trouble finding a 49mm for the Olympus here in the UK so 32mm I imagine will be nigh on impossible...

I would rather avoid a bulky filter system like the Kodak. The Minox is all about compactness and discreetness.
