So what crop factor will medium format have when it hits the popular public use trail? Or will users of medium format just read the focal length of their lenses of the the lens body and happily compare this to the focal length of everything else which is at present related back to 135 film standards on pretty well every lens in the pack.

A FF sensor is 36x24mm

The sensor in the Pentax 645D is 44x33mm

If you do the math, this means the medium format Pentax has a crop factor of 0.59.

Thanks Marty, I am a lazy sod, I thought some bright spark would work it out for me

But my point now is: if the medium Format is larger then do we make it the new "standard reference" and work all other sensors from there (hardly).  Or do we start looking at medium format lenses and start working out their true equivalent focal length on the FF sensor and then extrapolate this back to aps-c sensor to get the equivalent of  medium format on aps-c based on the FF sensor "standard".  What fun!

To cap it off it is possible to adapter medium Format lenses on to aps-c? Or am I simply being mentally lazy again ....
