I've not seen a lot on this subject on UHH before. When I was younger, my eyesight was a lot better. Now that I'm in my sixties, the viewfinder has taken on far greater importance--if I can't see my subject, what's the fun of trying to take good pictures?
For me, at least, a good viewfinder (digital or otherwise) has become an absolute must. How do you feel about cameras you've shot, and is excellence in viewfinder design, magnification, percent of coverage, etc., important to you?
I don't think the perfect viewfinder will ever be invented, but we are getting closer to wonderful with each iteration.
My first cameras as a kid had separate optical viewfinders. They suffered from parallax error, OR they displayed a mirror image of the subject, AND parallax error. Enough said...
Since my first SLR experience in 1968, I have absolutely hated the reflex mirror and pentaprism system, for two reasons.
First, foremost, is viewfinder blackout at the moment of exposure. At least with a TLR, you could see the moment of exposure. You knew a person's expression was "on" or "off". But the SLR hides that (and the dSLR does, too). At nearly six frames per second, my Nikon F3 was very hard to keep pointed at a moving subject, let alone focus manually!
Second, is that it is difficult to see depth-of-field at smaller apertures when pressing the DOF preview button. And, of course, the converse advantage of this is that you focus the lens at maximum aperture, so it's easier to establish precise focus, at least with wide aperture lenses.
When electronic viewfinders came along, they weren't very good, at first. They were low-resolution, had smearing and other color artifacts when panning or recording action, and they lagged the real-time event you were photographing so severely that action photography was impossible. By the time the action peaked in the viewfinder, the subject was out of frame when the shutter opened. Yuck.
Now, however, the EVF has been refined to the point where it is actually quite usable. Most digital cameras made in the last few years have much better EVF performance. So now, I actually prefer them for all applications except, perhaps, fast-moving sports. Yet with the latest cameras, electronic shutter speeds are so fast that the delay is livable.
EVFs show you a bright, processed bitmap image that looks like the JPEG that will be saved by the camera. You see the DOF, if you use a manual aperture lens. You see the actual effects of ALL menu and exposure settings. If you don't like them, you can adjust your settings and KNOW you got the image you wanted, because you saw it before you took it! Want to work in black-and-white, but do it in post-processing? Set the camera for B&W, view in B&W, but save a raw (color) image you can convert later, any way you want... including using it in color!
Of course, cameras without optical viewfinders OR EVFs have been around for over a decade. The most popular single "camera" on the planet, the Apple iPhone, has no viewfinder, just a large LED-powered LCD display. While the latest round is almost bright enough to use outdoors, it is still lacking.
That said, I have my iPhone at all times. It is the best camera I have, when it's the only one I have around.
I'm not sure I would say a viewfinder is the most important part of a digital camera. That, I believe, is the same as it was with film... YOUR BRAIN. Seconded by that is the LENS. Then the SENSOR. The viewfinder is somewhere down my list.
