The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) and mirrorless camera design and development.
The Olympus E-1, introduced in 2003, was the first DSLR system camera designed from the ground up for digital photography This contrasts with its contemporaries which offered systems based on reused parts from previous 135 film systems, modified to fit with a sensor size of APS-C.
A digital single-lens reflex camera is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor.
The Olympus E-300 is an 8-megapixel digital SLR manufactured by Olympus of Japan and based on the Four Thirds System. Announced at photokina 2004, it became available at the end of 2004. It was the second camera to use the Four Thirds System, and the first intended for the consumer market.
In photography, through-the-lens metering refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter. In some cameras various TTL metering modes can be selected. This information can then be used to set the optimal film or image sensor exposure, it can also be used to control the amount of light emitted by a flash unit connected to the camera.
The Olympus E-500 is an 8-megapixel digital SLR camera manufactured by Olympus of Japan and based on the Four Thirds System. It was announced on 26 September 2005. Like the E-300 launched the previous year, it uses a Full Frame Transfer Kodak KAF-8300CE CCD imaging chip.
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.
The Olympus E-330 is a DSLR launched on 30 January 2006, using the Four Thirds System lens mount standard. Its main feature is its live image preview functionality, permitting an image to be previewed on the LCD screen. While live image preview is not new in compact digital cameras, the E-330 is significant because it was the first digital SLR to offer this feature. With the ability to digitally zoom in 10× before taking a picture, it is very well suited for exact manual focussing, for example in macro photography.
The Olympus E-400 is a digital single-lens reflex camera launched by Olympus on 14 September 2006, using the Four Thirds System lens mount standard. This 10 megapixel camera could be compared to other DSLRs unveiled during the summer of 2006 with comparable pixel count and price range: the Sony α 100, the Nikon D80, the Canon EOS 400D and the Pentax K10D.
The Olympus E-510 is a 10-megapixel digital single-lens reflex (DSLR) camera oriented to the "prosumer" or "hobbyist" market.
The Olympus E-410 is a 10 megapixel digital single-lens reflex (DSLR) camera intended be the smallest and lightest DSLR on the market. Announced in March 2007 to succeed the E-400, it adds a live preview function and a new "Olympus TruePic III" processing chip that is claimed to provide better performance.
A dust reduction system, or dust removal system, is used in several makes of digital cameras to remove dust from the image sensor. Every time lenses are changed, dust may enter the camera body and settle on the image sensor.
