I'm one of those "lot of folks" that it never seems to bother. In fact, with
enough use you start to see "through" that pixelation. I grew up on everything
from twin-lens-reflex to SLRs, to DSLRs, I don't miss any of those optical
viewfinders, not in the least. In an EVF/LCD the details become averaged over
more than one pixel as you move the FOV around, your mind's-eye reassembling it
into fine details. No different than how much detail you can perceive in your TV
screen, those individual hairs on someone's head become discernable, even though
its data resolution is only 360x240 at best. That's because you see different
detail from frame to frame and your mind reassembles it. It becomes second
nature to see the extra detail in an EVF/LCD in the exact same way. Guess what
the resolution of the S3 IS display is? 360x240, the very same resolution as
your (old) TV display, that never seemed to bother anyone for over 50 years.
Everyone use to pride themselves on how sharp and clear all that detail was in
them (until HDTV came along, and not everyone has that still).
Then there's ways to learn to use that pixelation to your advantage. First of
all the main use is for framing, composition, and watching for exposure and
colors. It does that just fine. Plus displaying a plethora of exposure and
camera settings (I love that about an EVF). You don't need high resolution for
any of that. Now comes the snafu, using it for manual focusing or checking for
focus. Here's the ONLY reason people have problems.
I discovered and use this technique using low-res EVFs/LCDs over 7 years ago
when I got my first digital camera with an EVF.
Think of the screen as a "reverse microprism" focusing screen. Like the
micro-prism pattern that you remember from SLR, and DSLR screens. You know, that
small area (usually in a ring pattern surrounding a split-prism in the center)
that they have to assist with more accurate focusing? All the little diamond
patterns scintillate until your subject is in focus, then the little
micro-prisms disappear and it becomes clear as plain glass when in focus.
Well, just think of that in reverse. On a low-res EVF/LCD, any contrasty
textures and edges will cause the display pixels to scintillate only when they
ARE in focus, not out of focus. This is caused by the small details passing over
the pixels, changing them independently. When something is blurry more than 1
pixel will be affected as the blurry details move over them, no scintillation.
You just have to train your eye to watch for this effect. Once you learn to see
it you'll find that focusing on a low-res EVF/LCD display to be even faster and
more accurate than using an optical viewfinder with the best focusing screen.
Because the whole EVF/LCD is one huge micro-prism array (but used in a reverse
method). This allows you to see ALL parts of your subject that will be in focus,
not just the teeny area you might have situated right where a small micro-prism
area exists on a focusing screen.
Try it, you'll be surprised just how fast and accurate you can focus with any
EVF/LCD. It takes a sharp eye to learn to see that scintillation at first, but
once you learn to recognize it you'll start to wonder how you missed it all
those years. In fact one camera that came out this year is using that to its
benefit, I'm pretty sure it's one of the Sonys. (Maybe someone from their
company read one of my posts from 6 years ago about this, I did after-all first
announce it on a Sony forum.) Their camera detects that scintillation
electronically then enhances it with a highlight color. I thought that a nice
gimmick but not needed if you train your own eye to see it in any camera's
EVF/LCD.
Is a higher resolution EVF/LCD nicer? It can be. It all depends on how bright it
is and what the camera is willing to display in it. I've not found one EVF/LCD
that was better than another. Higher resolution is nice but when not available
low-resolution has its benefits too. Learn to see and use things in new ways and
you'll have few complaints about any of them.
