    no, but i had one and miss it dearly. i do own a d70 now and it obviously is
    another class of cameras (it IS a DSLR), but every now and then the point &
    shoot capabilities of the UZ would still come in handy. also it produced
    superb images for a 2mp cam...

    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

    etc. etc.

    Cheers,

  6. Those are required.
    Not required, at least by the rpd.zlr charter, though most ZLRs do have
    them.

    Would that only apply to cameras where you can change these parameters
    without going into a GUI?

  9. I don't see that pushing a button or operating a wheel affects whether you
    /can/ control these parameters or not.

    It's not that you can control the parameters, but how easily it can be done
    while shooting. I have two SLR's, a Maxxum 7xi and a Maxxum 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.

    On most P&S cameras it is more tedious yet for most cameras as these options (if
    available) are buried in menus).

    Well, having to go into a menu while your subject changes or leaves is
    not SLR-like photography, IMO.

  12. It is an EVF. Unfortunately, the vote for new groups here decided
    for totally wrong names and charters. Here is a list of relatively
    correct names IMHO. BTW - voting is almost always the wrong method for
    deciding what is wrong or right. Even my list is up to some discussions.
    But it is 1000 times better than was decided here - still IMHO.


    SLR (Single Lens Reflex)
    ------------------------
    You look through the actual lens via a removable or semi transparent
    mirror or prisma. The D20 is SLR (and SLR system). The E-10 and E-20
    are SLR (and ZLR). NOTE - SLR do not need to have interchangable
    lenses.

    SLR System
    ----------
    A SLR camera with interchangable lenses. The D20 but not E-10
    and E-20 are SLR system.

    Digital SLR system are also called DSLR. This is an anomaly though
    - the should be called DSLR system as DSLR should mean Digital SLR.

    TLR (Twin Lens Reflex)
    ----------------------
    You look through a similar leans. The old Rollei is an example.
    No such digital cameras exist.

    TLR System
    ----------
    TLR camera with interchangable lenses. Mamaya made one. Still,
    no such digital cameras exist.

    ZLR (Zoom Lens Reflex)
    ----------------------
    A SLR camera with a non removable zoom lens. This acronyme was
    invented by Olympus that had several ZLR cameras for film.
    The E-10 and E-20 are ZLR. There are some few more, but not many.

    EVF (Electronic View Finder)
    ----------------------------
    A camera with an electronic viewfinder (that I assume shall look
    through the actual lens, but I am not sure). The 2100uz is an EVF.

    EVF (Electronic View Finder) System
    -----------------------------------
    Am EVF camera with exchangable lenses. No such system exists.
    Personally I think this is a potential success when EVF becomes
    faster and better than today. Focussing also needs to be improved.

    Range Finder
    ------------
    A camera with a coupled distance meassure of double image type.
    Lots of oldies are of this type.

    Range Finder System
    -------------------
    A range finder camera with exchangable lenses. The classical Leica
    and others. The new Epson thingie falls in this category.

    Compact
    -------
    A camera that is compact :) Almost all digital cameras fall into
    this category and so do almost all film cameras. My G2 does.

    Point&Shoot
    -----------
    A camera that is very simple and that you only can point and shoot
    with. Really no settings available at all. There are very few
    digital P&S cameras - and probably none discussed at news forums -
    except maybe as a light weight camera for hobby aerial photography.

  13. 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.

    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.

  16. 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.

    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).

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

    Thanks,
