What is SLR technology?

Answer 1

The single-lens reflex (SLR) is a type of camera that uses a movable mirror placed between the lens and the film to project the image seen through the lens to a matte focusing screen. Most SLRs use a roof pentaprism or pentamirror to observe the image via an eyepiece, but there are also other finder arrangements, such as the waist-level finder or porro prisms.


Digital SLRs
Canon, Nikon, Samsung, Pentax, and Minolta have developed digital SLR cameras compatible with their film SLR systems (though Konica-Minolta recently sold its SLR camera division to Sony who will continue manufacturing), while Olympus and Panasonic have introduced a new digital-only SLR system, the Four Thirds system

Answer 2

SLR - Means Single Lens Reflex.

When you look through the eyepiece of a SLR, you are seeing what is going to be captured on film. When you press the shutter button, the mirror that reflected the image into the eyepice flips up to allow the light through to the film or in the case Digital SLR, the sensor. Thats why you hear the click, you'll notice that the view through the eyepice has gone dark... That's the mirror flipping out of the way to allow light through to hit the film/digital sensor.

There are many cameras that have a lot of the features of the DSLR, but have a fixed lens/or no lens reflex. These are reffered to as DSLR-like or Prosumer. The main difference between these are that the DSLR likes have a electronic viewfinder, almost like a closed circuit tv, and that they have a fixed lens. You cannot change it. But for most, these are great cameras.
There are many different ways that camera manufacturers have come up with their own SLR systems.

The most popular are:
Canon
Nikon
Olympus
Pentax
Sony/Minolta
Panasonic
and many more

I hope this helps!

With SLR you're watching via the precise lens versus different virtual cameras in which you're simply watching via the viewfinder. Less correct picture placement and focusing for a non-SLR virtual digicam -additionally much less pricey too. H a p p y P h o t o g r a p h y !

Answer 4

The fundamental principal of SLR type camera is the TTL (Through-The-Lens) mechanism. TTL means that the scene is viewed, focused and metered directly through the lens. Incoming light is reflected by a “reflex“ mirror towards pentaprism (all-glass, or a roof-mirror type as a smaller and cheaper solution). Then prism re-directs light to the viewfinder. As result, viewfinder shows a scene through the "eye" of the lens. The amount of transmitted light is roughly dependent on the maximal aperture of the lens so the faster the lens the brighter is the viewfinder. Quality of pentaprism also matters and all-glass types usually provide brighter images.
