Re: Viewfinder D40/D50 Surprise

D50, D40, whatever, both viewfinders suck, the D40 just slightly less so. Even the D200 viewfinder is just barely adequate for manual focus and I'm being generous. I own the D50 and have played with the D40 a few times and the viewfinder magnification is nothing to write home about.

And as far as a brighter viewfinder being easier to focus manually, actually it can make it worse. What you don't realize is that in most cases, it's not the viewfinder itself that's getting brighter, (unless they switch from using a pentamirror to a true prism) but the focusing screen. The only way they can make the focusing screen brighter, is to make it clearer (less frosted). This in turn reduces the ability of your eye to focus on the image appearing on the ground glass. An almost clear screen presents a brighter image, however that image is almost an aerial image in the viewfinder and you have little or no ability to judge DOF or focus accurately.

Simple test: if you have a 50mm f/1.8, shoot something fairly close to the camera wide open (use a tripod) and then bring up the image on screen. Observe the zone of sharp focus. Now look through the viewfinder and observe the zone of sharp focus. You'll see that the viewfinder image appears to show a much wider zone of focus (DOF) than what appears in the actual image. What does this mean? It means that trying to focus that lens manually will be a hit or miss affair as your viewfinder is not showing you where the true zone of sharp focus actually falls.
