Sorry if this seems like a simple question...
What does DSLR stand for and what is the difference between them and the other 'conventional' digital cameras?
thanks for calrifying for me... |

A type of camera in which the photographer looks through the actual taking lens when he or she peers through the viewfinder.
Light entering an SLR camera lens hits a mirror installed in the body at a 45° angle, which deflects the light up into the viewfinder pentaprism. When the photograph is actually taken the mirror flips up out of the way, the shutter opens and light strikes the surface of the film behind it. (the one exception being fixed pellicle mirror SLRs)
SLRs have a couple of very significant advantages. First, they do not suffer from parallax error, which makes them useful for closeup or macro photography. Second, what you see is mostly what you get - you can see the effects of filters, for example, before you take the photo. The image in an SLR viewfinder is also not reversed or upside-down, as is the case with TLRs and view cameras.
There are also a number of disadvantages to SLRs. First, the pentaprism is bulky - it̢۪s the large hump on the top of an SLR. Second, the noise of the mirror slap means that SLRs are always much louder to operate than, say, rangefinders. Third, there is a brief mirror blackout period on most SLRs during which nothing can be seen in the viewfinder (fixed pellicle mirror SLRs being the one exception again). And finally, the mirror forms a physical barrier for the design of very wide-angle lenses, requiring inverted telephoto construction.
Layman's: The super cameras with the flexability to change lenses for different subjects and different situations. Difficult to master but a blast to try because of the great pictures that you can capture :)

there are 3 main types of digital cameras on the market today -
rangefinder, some with zoom. htese have the lottle viewfinder that is in a corner of the camera, a small lens. (under $400)
'prosumer' - imitation SLR shall we saw. Look a lot liek an SLR, but the viewfinder is electronic and the lenses are not interchangeable. You can get teleconverters and w-converters to get more range in the lens (t-con for tele and w-con for wide angle. more features (manual modes, etc) larger lenses and sensors (usually) $400 to $1000
dLSR - two types - the main diff being the higher end ones have larger ccd or cmos sensors, and of course cost more ($2,000 to 20,000). The lower end ones start at $1000 to $1500 and that includes one lens, usually a fixed 50mm or so lens. To do much you will want more lenses, perhaps a 17-35 wide angole and a 70-200 zoom. the larger teh aperature (2.8 vs 4 or 5.6)a lens has the bigger it is, the heavier it is, the more it costs bet generally the better it is. Lenses start at $200 or so and can go to $3000 or more each.
The tradeoff from dSLR to Prosumer is less flexibility, but less cost and less to carry around. |

| Both good answers but if you ar wondering what dSLR stands for, It's Digital Single Lens Reflex. |
