What is a Digital Camera SLR? What does it stands for?

Answer 1

Hmm, not very useful- that link is just a bunch of Canon prices when I click on it?

SLR means "Single Lens Reflex"

This means that when you look through the viewfinder of the camera, you are looking through the same lens through which light will pass to the film (or in the case of digital cameras, to the sensor)

With compact cameras and other non-SLRs, there's a separate lens you're looking through, so you might actually have then lens cap on, or a finger over the lens and not realize it until you see the picture (really bad with film, because you only see the results after you've developed it & that could be weeks later)

With an SLR, if the lens cap is on everything is dark- if your hand is covering half of the picture-taking lens you see that. The biggest advantage of SLRs besides seeing exactly the same image that will expose the film/sensor is that SLRs have interchangeable lenses. You can remove lenses and replace them with different types- wide-angle lenses for landscape shots and telephoto for sports or wildlife, where you need to shoot from far away.

Here's more info on the difference between digital SLRs and non-SLR digital cameras, hope it helps:

Answer 2

The digital SLR is a marriage of the best of both worlds: the convenience of a digital camera with the flexibility of an SLR. Once priced sky-high, now they are starting to drop in price.
single-lens-reflex (SLR) camera.

This is a camera where the photographer sees exactly the same image that is exposed to the film and can adjust everything by turning dials and clicking buttons. Since it doesn't need any electricity to take a picture, a manual SLR camera provides an excellent illustration of the fundamental processes of photography.

DSLRs are conceived for professional photographers and are well adapted for action photography or specialized uses. They are based on film single-lens reflex cameras and retain their main features : image composing done through the optical viewfinder using a mirror reflected image and exchangeable lenses, albeit a few early SLR digital cameras like the Olympus E-10 have a fixed lens.

The ability to change lenses gives the same benefits as in film cameras, allowing tailoring a lens to an intended use instead of a compromise. They can use the same lenses as their film counterparts, but the sensor is usually smaller than that of 35 mm film. A common term is "APS class," being the same general size as APS film. Focusing on the smaller area results in digital cameras having a zoom of 1.5 to 2.0 times over the same lens on a 35 mm film camera. Thus a 50 mm lens on a DLSR with a 1.5 crop ratio would show the same angle of view as a 75 mm lens on a 35 mm camera.

DSLR cameras have larger image sensors than compacts or prosumers, and thus higher sensitivity in dim lighting and less noise overall in the pictures they take. They usually are instantly on and the autofocus and operation is faster. Most of them can save in JPEG and raw formats even simultaneously.

They are bulkier, heavier and frequently much more expensive. Two characteristics many consumers are surprised to find due to the reflex viewfinder is they cannot record movies and the screen is only for reviewing pictures. All composing is done through the optical viewfinder which has more resolution than an electronic viewfinder and does not produce any delay. In 2006 the Olympus E-330 is the only DSLR that can use the LCD for a live preview, and will be joined by the Panasonic Lumix DMC-L1.

Answer 3

I believe it stands for single lense reflex. All it means is when you look through the eye piece you are seeing exactly what the lense of the camera does, It would be the same as being able to look down the barrel of a gun to aim. It helps alot and is usually on high end professional camera's with high magnification lenses.
