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, David > On a ZLR one would look > for: > > - SLR-like format > - zoom > - full manual control of aperture, shutter speed and focus Those are required. > - hot shoe Not required, at least by the rpd.zlr charter, though most ZLRs do have them.

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

[] 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.

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. David [] > It's not that you can control the parameters, but how easily it can > be done while shooting.

I looked at the 300D review and saw neither an aperture ring nor a shutter speed dial. David >[] >> It's not that you can control the parameters, but how easily it can [quoted text clipped - 12 lines] > >David 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).

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).

Sounds rather like the cameras I've handled (which fall into the ZLR category). Thanks, David >Yes, it does, JC. Sounds rather like the cameras I've handled (which fall >into the ZLR category). 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. jc >>> - full manual control of aperture, shutter speed and focus >> [quoted text clipped - 3 lines] >I don't see that pushing a button or operating a wheel affects whether you >/can/ control these parameters or not. Well, having to go into a menu while your subject changes or leaves is not SLR-like photography, IMO.

SignatureMichael Meissner email: mrmnews@the-meissners.org http://www.the-meissners.org > I have an Olympus C-2100uz. Is this a digital slr? Thanks 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... Then I guess I just don't understand what the difference is. This camera has a full set of manual controls and a range of aperture and shutter speeds. How is this a point-and-shoot and how does an slr differ? Thank you. Sorry for posting this as a new message but I am unable to respond to messages in this group. "cannot be resolved" issue which, so far, cannot be resolved :-( "David H.

Thanks More of a "zlr" (zoom lens reflex) as it has a non-excangeable lens, doesn't seem to have a flash hotshoe either...

Is this a digital slr? Thanks 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. /Roland |
