Many people have heard of a digital single lens reflex (SLR) camera, but aren’t exactly sure what it is. This type of camera uses the same lens for viewing and taking photographs. The images are reflected onto a viewing screen by a moveable mirror that’s located inside of the camera.
The mirror will then flip out of the way when the shutter is released. This will enable the camera to receive light and the image you get in the photograph is identical to what you see through the lens.
SLR cameras are quite versatile and easy to operate. They are equipped with automatic, semi-automatic, and/or manual controls over the camera’s shutter speed, aperture, and focus. Most models will let allow you to override the device’s autofocus system with the manual focus.
Digital SLRs come with camera bodies attached and are designed for use with a variety of interchangeable lenses such as fisheye and zoom models. The cameras can also be used in tandem with assorted accessories such as monopods, tripods, flashes, and remote shutter releases.
Most digital cameras come with a small internal flash system, but they’re also designed for using larger detachable and hand held flashes. You can use digital SLR cameras underwater if you have the proper type of housing units for them.
Digital SLR cameras are available in various sizes, shapes, and styles. They generally range in price from a few hundred dollars to over $20,000.
