I love this page, which has been mentioned already, showing different sizes of viewfinders pictorially:
Standard versus Enhanced Viewfinders - Size Matters :: Wetpixel.com
Did a quick update/calculation of my own:
Code:
Name Viewfinder Visible Diagonal (sensor diagonal x mag x coverage)
5D Mark II 30.10
Nikon D700 29.59
Nikon D90 26.17
Olympus E-3 25.88
Pentax K100D 23.06
Pentax K20D 25.38
Sony A900 31.96
To me it's kind of like buying a TV - I like them big
The thing that makes it a hard call is that in this analogy, the Olympus is a standard TV, everything else is widescreen. So using the diagonal is not fair to the Olympus. Sorry, Olympus!
P.S. The old film classic Pentax K1000 would be 38mm x coverage. Guessing coverage at 93% that would be 35mm viewfinder visible diagonal. The Sony A900 is getting close...
