Please anyone correct me if I am wrong here but they are made for thin gel type filters like those used in lighting - I personally wouldnt use it due to the lack of optical quality of this sort of filter, but they could come in handy with wider lenses that you didn't want vignetting issues ...
Is there a higher optical spec thin filter range offered for these in-camera behind the lens filter slots ? (coated glass, consistent etc...)

B&H Photo is the place to buy.
The optical quality is quite good. But they don't stay flat in humid conditions.
Ideally your lenses should be collimated / rear focus set with the thickness of the gel filter allowed for. The recomendation is to use a clear filter when you don't want "filtration" i.e 85, ND, etc.
I've cheated and just used an empty one however.
You always want one of the fliter holders / clips in position as you'll fog the side of the film otherwise.
