So you're thinking of buying a new camera, eh? You're used to buying the typical, runshoot viewfinder. Digital SLRs run basically the same way with a few different capabilities and features.
Features on DSLRs
*Digital SLRs (DSLR) cameras will often have what is called a phase detection autofocus, which will split the image into two, at which point the camera will compare the light in both images to determine the depth and focus.
*Older DSLRs don't have a live preview system to help you see the image exactly as it's being shot, but the optical viewfinder on DSLRs should show you the result you'll get in exposure.
*The live preview is an LCD screen with the image displayed so you can have another way of deciding whether or not you want to expose the film.
*Some DSLRs are highray discs.
*Like all SLRs, you can adjust settings like ISO, focus, shutter, etc.
*Some DSLRs are capable of capturing ultraviolet and infrared, but it is not common.
Benefits of DSLRs
*There are more apertures available for these cameras than normal pointshoot types. They are great for lower light settings for this reason.
*Light meters, flash, and lenses are easily attachable.
*They take more accurate, clearer photos, because there is a better focusing system and less shutter lag.
*They are professional cameras and produce higher quality results.
*The faster shutter and frame rate is much better for capturing sports photos and other action shots. You want to see that amazing catch in its full glory, not a blur.
Downsides
*They're kind of bulky and aren't as portable.
*They're expensive. You'll want to really do some research to choose the model you want, do not just "browse."
*They're delicate. Take care of them and make sure you buy cases to protect their accessories as well.
