view finder of P645N larger than P67II??

I got a P645N... and looking through the view finder I am surprise to find out that the 645N viewfinder window area appear to be larger than my P67II?

Is this true of just I am missing something?

Viewfinder size/magnification is a very complicated and somewhat convoluted topic.
The 645nII does have a .76x finder with 92% coverage, while the 67II prism is .70x, with 90% coverage. So it is smaller magnification wise, but with the larger frame size, you'd think it should still be bigger.
The lens on the camera also makes a difference AFAIK.
The 645 viewfinder often seems bigger and brighter than the numbers would suggest.

In theory, it should be the 67II, but I unfortunately don't have both cameras on me to compare

The two system have very different finders. The 67II uses a roof pentaprism, while the 645 uses a trapezoid prism with a Keplarian finder. The trapezoid prism was used to save weight.
