Hi Richard,For the record I have shot with the n14, D1x, D100, 10D, D30, S1,
S2, Sigma SD9,and a Mamiya 645 w/DCS pro back....I hope at least a
couple of those qualify as pro cameras. None of these cameras is
within a 1/2 stop of my 20 year old 8008s as far a viewfinder
brightness, and most are a full stop dimmer....measurements taken
at viewfinder with same lens aperatures and focal lengths...(Mamiya
was not done with this test)..all focused on white sheet of paper
with same illumination with a 1 degree spot meter in ambient mode.
Included in this test were Canon Pellix, Nikon FE, Nikon F, Nikon
F2, Nikon n70, Nikon 8008, and 8008s film bodies. I haven't
handled the 1D, nor the 1Ds. I am currently trying to use the 10D
camera......
A camera with a reduced field of view vis a vis a reference platform such as 35mm will have less frame in the viewfinder, and often less brightness simply because one is not using the full extent of maximum rectangle within the circle of definition provided by the lens. But you mentioned a 645 with a pro back and a 14n. It's illogical to claim that there would be any difference in the brightness of the viewfinder since the identical lens is being used or can be used and we are simply talking "mirror" TTL image. Whether a film plane or digital sensor is behind the lens is totally irrelevant and has no bearing on the brightness. A Mamia 645 doesn't suddenly have less light through the mirror to the viewfinder because it's being used with a digital sensor instead of film. That makes absolutely no sense.
The viewfinder on a 10D is definitely dim by 35mm film or by full frame digital SLR standards, but the viewfinder on a 1DS or a 14N is no different than on any other 35mm platform camera and the fact that the sensor is digital has absolutely no bearing on brightness in the viewfinder.
