People don't realise just how utterly crap modern viewfinders are. Pick up an old Nikon F, or even a Pentax K1000 ...
This is one place that I can modtly agree with the nostalgic curmudgeons: the arrrival of auto-focus drove SLR viewfinder designs in a direction that perhaps works better when using auto-focus, but at the cost of not supporting some things like manual focusing as well. But ...
... now everybody has liveview and is squinting at their pathetic LCD screens thinking that this is photography.
There is of course another option, the EVF, which for often stated reasons (the ability to magnify near the desired focus point, possibly with the overall framing still shown around the zoomed portion; DOF preview without dimming of the image; the ability to "switch screens" to get various overlays like grids for vertical and horizontal alignment ...) can be far better than any optical viewfinder in most respects. The main remaining EVF disadvantages relate to fast moving subjects and lag, which is now down to 1/120s or maybe even 1/240s.
In a pinch, even the zoomed image on a rear screen is a more precise focusign tool than any optical viewfinder, even those in medium format cameras. It is ironical that this much-maligned composition tool so closely resembles the top-down ground glass viewfinders of older MF designs. The 56mm width of those VFs with 6x6 or 645 is about the same as with a 3" rear LCD screen.
Of course, there are not yet any 35mm format cameras with EVFs, but there will probably be one later this year, in the form of a Sony "SLT" to repace the discontinued A900 and A850. I wonder why no SLR maker has yet offered an accessory tiltable EVF, usable in the hot shoe.
