It's not showing the light that's actually there. It can't. It *really* can't generate full spectrum light or comparable brightness to daylight or anything like the full dynamic range of a scene with complex lighting, in the same way even really good monitors have trouble with better than about 1:250 contrast ratios in actual practise. This may not be important for what you are trying to do; it's definitely important for what I'm trying to do. And yes, you can display a magnified central view and so on; this is almost totally useless if what you're trying to focus on is moving in an even modestly erratic way. (Eg., warblers.)

I don't think it's even close to being an either-or question, myself. There's a range of things the EVF is good for; there's a range of things the optical viewfinder is good for. The range of people with different objectives maps to those ranges in some modestly discontinuous way. Never mind the pretty obvious technological possibility of combining the two. > I much prefer using my nice old Pentax manual prime lenses on the G1, > where I can focus them extremely accurately, quickly and easily see > the choices in DoF. This is impossible to argue with. Similarly, that my experience of using EVF viewfinders is one I find only marginally preferable to a diet of red-hot, razor sharp rocks delivered through a medium of diseased sludge under pressure is *also* impossible to argue with, unless you want to privilege your own preferences as normatively correct. -- Graydon -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
