Live preview is useful in situations where the camera's eye-level viewfinder cannot be used, such as underwater photography where the camera is enclosed in a plastic waterproof case. In 2000, Olympus introduced the Olympus E-10 , the first DSLR with live preview – albeit with an atypical fixed lens design.
These mirrors are so small that DMD pixel pitch may be 5.4 μm or less. [2] Each mirror represents one or more pixels in the projected image. The number of mirrors corresponds to the resolution of the projected image (often half as many mirrors as the advertised resolution due to wobulation).
The first digital rangefinder camera commercially marketed was the Epson R-D1 (released in 2004), followed by the Leica M8 in 2006. [16] They were some of the first digital lens-interchangeable cameras without a reflex mirror, but they are not considered mirrorless cameras because they did not use an electronic viewfinder for live preview, but, rather, an optical viewfinder.

Hasselblad 503CW with Ixpress V96C digital back, an example of a professional digital camera system. A digital camera, also called a digicam, [1] is a camera that captures photographs in digital memory. Most cameras produced today are digital, [2] largely replacing those that capture images on photographic film or film stock.
The surface of these devices is covered by a very large number of microscopic mirrors, one for each pixel, so a 2K device has about 2.2 million mirrors and a 4K device about 8.8 million. Each mirror vibrates several thousand times a second between two positions: In one, light from the projector's lamp is reflected towards the screen, in the ...
Samsung NX1 - First prosumer camera to record in HEVC, 4K downsampled from 6.5K, 80 Mbit/s in H.265. 30 min max recording time limit Samsung NX500 - Same 28 MP APS-C sensor as NXI but 4K video is not downsampled from 6.5K so less details and more noise than the NX1 - with this 2.4× crop factor the kit lens become a 38–120mm f8.5–13.4 ...
Four Thirds logo. The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) design and development. [1] Four Thirds refers to both the size of the image sensor (4/3") as well as the aspect ratio (4:3).
Drawing showing the relative sizes of sensors used in most current digital cameras, relative to a 35mm film frame. The image sensor of Four Thirds and MFT measures 18 mm × 13.5 mm (22.5 mm diagonal), with an imaging area of 17.3 mm × 13.0 mm (21.63 mm diagonal), comparable to the frame size of 110 film. [4]
