I disagree.

Please explain where the light path is bent in a EVF camera.

If there is no reflex in the optical path the "R" is indeed
misleading. Whether or not you disagree with it has no
effect on the actual meaning of the "R" in a reflex camera.

I propose the terms "EVF camera" & "EVF digicam" to describe this class
of digital camera.

No thanks.

On that I can agree, although it's substantially more
accurate than "ZLR".

The electrical path is bent.

There's nothing that restricts "reflex" to optical.

There is no such "actual meaning". Language evolves.

I think ZLR is more descriptive and accurate.

I've explained this in great detail. Please refer to that post.

What do you suggest then?
This type of digital camera only really has the EVF as their common
trait: some have an ultrazoom lens and some have a modest zoom lens,
some have mechanical zoom and others zoom by wire, some look like "fake
SLR" and others just look different to anything else, some have large
sensors and some have small sensors.

What's your suggestion?

The reflex is electronic.

An electronic reflection?
Are electrons being reflected into the viewfinder or are you just being
facetious?

It is time to move this thread to r.p.d.zlr.

That would make it the only non-spam since some time in mid December
last year, even that was only the last spasms of the "DSLR Vs P&S equals
film Vs didgital" thread which was crossposted to here (and
alt.photography) anyway.

It's left-right or up-down reversal. If you have a single mirror, the
image will be inverted or left-right reversed, hence the need for the
second mirror (penta-mirror or penta-prism) in the SLR. Other TTL cameras
(such as plate cameras) produce an upside-down image. ZLR cameras can
avoid any inversions (or reflexions) purely by electronic means.

You are correct up to this point, but no farther.

No they don't.
A ZLR camera is just an SLR cameras with a zoom lens integral with the
body, they do not have an EVF.
ZLR cameras have a TTL optical viewfinder, just like any other SLR camera.

Just because you want an EVF to be a reflex viewfinder does not make it so.

I have two ZLR cameras here which both have EVFs - the Panasonic FZ5 and
FZ20, and arguably the Nikon 8400 as well.

The EVFs in my cameras function exactly as expected, providing a right-way
up image. I would not "want" them to do anything else.
