There is definitely a filter of some kind directly in front of the CCD, it has a slight tint so I guess it's a colour filter of some type but beyond that who knows. Unfortunately it's not fixed in such a way that it's accessible from the mirror box. In any case the absolute resolution that can be read off a lens test chart pretty much tallies with the practical limitations of (natural non- aliased) resolution for the density of sensor it is.
