Sort of, there are at least two Digital SLR Cameras out there from
Olympus the E-10 and E-20 neither of which had interchangeable lenses.

Those are ZLRs.

Yes they are - and they are also SLR. ZLR is Olympus name
for an SLR camera with a non interchangable zoom lens.

No it is a Point & Shoot with Zoom.

Or a zlr, using the wacky new group names.

A ZLR is not just a point and shoot with zoom; perhaps better defined as
an SLR-like camera with no mirror and fixed lens. On a ZLR one would look
for:

- SLR-like format
- zoom
- full manual control of aperture, shutter speed and focus
- hot shoe

Well the C-2100UZ has all that, except for the hot-shoe (but the FL-CB04 cable
gives you a pc-sync connection so you can fire off external flashes).

That's not relevant to a defintion - if all these parameters /can/ be
manually controlled then the camera could qualify as ZLR rather than
point-and-shoot.

9.
7xi: Changing between A-S and M modes; or setting exposure
compensation is a bit tedious (depress a button once or twice, then
turn a wheel to select).
On the Maxxum 9 I can do these without taking my eye from the
viewfinder and entirely by feel or by watching the exp. meter. Makes
shooting much less tedious to have these principal controls dedicated.

As a matter of interest, how do the popular D70 and 300D cameras compare?
I looked at the 300D review and saw neither an aperture ring nor a shutter
speed dial.

For the D70:

You change P/A/S/M mode by turning an "old-style" mode knob on the left of
the viewfinder; with practice, I'm sure you could adjust this by feel.

In these modes, two command-dials control one or both of shutter or
aperture. These are "thumbwheels" (or one thumb-, one fingerwheel) that
poke out front and back of the shutter release (i.e. the rear one is
roughly where the film advance lever would be. Visual feedback of what
you're doing is in the viewfinder, so you can adjust these easily without
taking your eye from the shot.

A few other settings (white balance/white balance adjust, ISO, exposure
adjust) can be changed by pressing a button and turning one of the wheels.
If you're a heavy user, you could probably get quite adept at changing
these without looking (though for some, I think you would need to remember
what the current setting was).

I didn't mean the above in the sense of definition but in the sense of what
makes helps a camera be a photographic tool as opposed to a widget. Full access
to the controls that one needs as one is shooting is part of a competent tool.
There are SLRs, ZLRs and P+Ss that fail in this regard, remaining whatever they are.

Completely agree, but the OP wanted a definition of ZLR.

I looked at the 300D review and saw neither an aperture ring nor a shutter
speed dial.

The 300D has a wheel, in P, M and TV modes its default behavior is to
change the shutter speed. In M mode when you depress a button on the
back of the camera the wheel changes the aperture, otherwise it
changes the shutter speed. In AV mode the wheel changes the aperture
without you having to use the button on the back to "select" the
aperture as the thing that gets changed.

When you select ISO, the wheel changes the ISO, when you select white
balance then the wheel changes WB. For this reason, the wheel is
unlabeled (it changes many things, depending on what is selected
elsewhere).

Yes, it does, JC. Sounds rather like the cameras I've handled (which fall
into the ZLR category).

Thanks,

I am not familiar with the exact description of a ZLR camera, but it
appears that one feature that they all seem to have is a built-in
zoom, such as the Canon PowerShot Pro1 and my old Olympus E-100 RS. I
don't think that cameras that A) have a reflex mirror and B) take
interchangable lenses such as Canon's EOS series cameras fall into the
ZLR category, I think those are the cameras that the SLR category is
for.

But I could be wrong.
