The Single Lens Reflex (SLR)

A Single Lens Reflex camera works by using a mirror in the camera which reflects the image up through a viewfinder to the eye. When the shutter button is pressed, the mirror quickly flips out of the way and allows the sensor (or film) to capture the image as a reflex action mechanism.

Generally speaking, SLRs are great for professional or serious photographers wishing to have total control over the image. Because SLR cameras use a mirror, there is generally no live preview of the image on the back LCD with these cameras. (A few models have recently been introduced which now include this feature however) Digital SLR cameras use many of the same mechanisms from the days of film and carry over many of benefits like quick response, durability, and precision images. Some of the basic characteristics of an SLR include:

• Removable lenses that can be switched out to include a variety of situations
• More control over focus and zoom, as well as better granularity in these controls
• Better flexibility and capability with exposure which allows for more creativity with how the picture is taken
• Little or no lag time when taking pictures
• Generally better quality pictures since the lenses are made of higher precision glass
• Usually no video or features normally found on consumer-level cameras
• Typically very expensive, especially lenses and accessories.

At the SLR level, we have tested and recommend two camera brands: Canon and Nikon. Both brands have a variety of camera model selections at different price points. Most photojournalists will use either of these two brands and both are well known as standards in the photojournalism industry.

We personally recommend the Canon Rebel camera for traditional journalists who are actively pursuing photography as a regular part of their workflow. The camera is flexible enough to grow with the user (with additional lenses and an external flash mount).
