EOS 6D with "Fixed Pentaprism"

[compupix]

I'm looking at a comparison of the 5D II, 5D III, & 6D

(The product page for the 6D is not yet loading on the Canon site.)

The 6D is the only one of the three to have an Eye-level SLR (with fixed pentaprism.) What does the fixed pentaprism mean?

DPReview does show a top view. It looks like the 6D does have the variable diopter correction.

It means the pentaprism cannot be removed and changed. My old Nikon F3 SLR has a removable and changeable pentaprism. That spec wording is archaic now since AFAIK no DSLR has a changeable pentaprism, even the 1-series.

Thanks!
Imagine that... an answer to the question... right off!

The pentaprism viewfinder in the 6D is really not that important, because most 6D users will be shooting video and will use the 100% LCD viewfinder on the back of the camera 99% of the time.
