Video will help kill DSLR mirrors
Rich
5DII, etc., it is clear that video applications and cost savings will doom
the reflex mirror from all but a niche of DSLRs within a few years. I'm
not sure we're at a point where that would be a good idea, but it is
coming.

Make that, the GH1, not G1H.

I'm not sure I undestand. What has video to do with overcoming the
problems with electronic view finders?
If we want to shoot video, we use one of our video cameras, specialized
for the task.
Is the video from the viewfinder somehow easing the focus problem?

Which focus problem are you referring to?

But, Dear Rich, you miss the point. Many DSLR consumers could care less
about video.
That mirror and the pentaprism will outlive your posts here.

LCD screen mostly but generally low res is fine for what they need to do.
dj_nme
No, film cine cameras use a variety of optical viewfinder types.
Some use a separate viewfinder, some use a type of reflex finder with a
half-silvered mirror and others use a reflex finder with a mirror which
spins through the optical path to the film, forming part of or attached
to the shutter.
Video cameras use a low-res video screen (either a flip-out LCD screen
or an EVF of some sort) which has a live feed off the sensor.

If you are doing manual focus, I have yet to see an EV that has enough
resolution for seeing the focus with adequate resolution. I do a lot of
macro work, where I want to place the plane of best focus somewhere
between edges (front to back), and AF doesn't do this very well.
Don Stauffer

to focus with that low a res. Even HD is less than 2 Mp.
J. Clarke
Well that's nice but the question was about FILM.

For accurate focus a tape measure often works best.

Well, manual focus through my A350 is unusable. It may be a DSLR with an
optical viewfinder, but the manual focus is by far too inaccurate. If I
try to manually focus I get blurred pictures.

Some had a reflex and prism viewfinder, others used a fixed prism
"beamsplitter" viewfinder. Current ones have an electronic viewer.

Yeah, my bad, he said "film", in which case it is often a separate view just
like the P&S film cameras.

I find my D40X to be right on for focus. You need to find a shop with a
good collimator and get that checked.
Don Stauffer
He didn't say which format, but my SD video far surpasses my old 8mm
movies. So 2Mp would be considerably above 8mm, even Super8.
Also, old 8mm format was so small, the standard lenses were very short
FL, so depth of field was very generous.
J. Clarke
So how does your SD video compare to 70mm IMAX?

True, but that won't influence the manufacturers if they can produce a
camera for $20 cheaper by deleting the mirror mechanism.

I ordered an Olympus E420 for my wife because it's the most compact &
light DSLR currently on the market and she needs fast AF to photograph
the kids. But she also does video occasionally with her current P&S so
it's a pity Olympus hasn't incorporated this function into the E420.
