well I think the thing to consider is that the volume of a FF Pentax DSLR would not be 1.5x1.5x1.5 = approx 3.375 times the volume of their APS dslrs because not everything has to be scaled up, just some things. I havent really done any studies on these, but I would have a hunch that the body + lens volume increase for going from APS to FF with Pentax would be much less than a factor of 3.375 to 1. In other words the format size increases proportionally faster than the body volume does when going from APS to FF body because of things that wont get bigger in the FF body.

While mount and register remain the same, the mirror box is significantly smaller which allows smaller bodies in practice from APS-C. As a practical matter the smallest FF DSLR (the Canon 5D) is the same size as the largest APS-C DSLR (the Nikon D300s) but overall APS-C DSLR's are generally much smaller than any FF SLR. Depth is pretty similar across the various lines (depending on grip configuration) but smaller prisms and the ability to put circuitry and batteries into places that would extend into the mirror box on FF allow more compact designs. > > 4/3 DSLRs are smaller than APS DSLRs are they not? > Arent the lens mounts smaller, and the registrations > shorter too? Lens mount is smaller, registration is a bit shorter at ~38mm, cameras are generally on the large side for their class (the E-3, E-30 and E-520 are all larger than their competition aside from the outlier than is the D300). The smallest available body is the Olympus E-450, but the smallest available body/lens combination is the Pentax K-m with DA Limited 40/2.8. > > > -- > J.C.
