The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) design and development. Four Thirds refers to both the size of the image sensor (4/3") as well as the aspect ratio (4:3). The Olympus E-1 was the first Four Thirds DSLR, announced and released in 2003. In 2008, Olympus and Panasonic began publicizing the Micro Four Thirds system, a mirrorless camera system which used the same sensor size; by eliminating the reflex mirror, the Micro Four Thirds cameras were significantly smaller than the Four Thirds cameras. The first Micro Four Thirds cameras were released in 2009 and the final Four Thirds cameras were released in 2010; by that time, approximately 15 Four Thirds camera models had been released by Olympus and Panasonic in total. The Four Thirds system was quietly discontinued in 2017, six years after the final cameras were released.
The Pen or PEN series is an Olympus camera brand. It was used on analog half-frame compact and SLR models from 1959 until the early 1980s. In 2009, Olympus released the PEN E-P1, a digital mirrorless interchangeable-lens camera, which opened the range of Digital PEN models, which are still sold today. Olympus Corporation's camera division since has been bought by Japan Industrial Partners, and run under the OM Digital Solutions name. They continue to run the Digital PEN series.
The Micro Four Thirds system is a standard released by Olympus Imaging Corporation and Panasonic in 2008, for the design and development of mirrorless interchangeable lens digital cameras, camcorders and lenses. Camera bodies are available from Blackmagic, DJI, JVC, Kodak, Olympus, OM System, Panasonic, Sharp, and Xiaomi. MFT lenses are produced by Cosina Voigtländer, Kowa, Kodak, Mitakon, Olympus, Panasonic, Samyang, Sharp, Sigma, SLR Magic, Tamron, Tokina, TTArtisan, Veydra, Xiaomi, Laowa, Yongnuo, Zonlai, Lensbaby, Venus Optics and 7artisans amongst others.
The Panasonic Lumix DMC-GH1 is a digital mirrorless interchangeable lens camera adhering to the Olympus and Panasonic developed Micro Four Thirds System (MFT) system design standard. Panasonic classified the GH1 as a hybrid stills/video camera and the GH1 was introduced and marketed as a higher end camera than Panasonic's first MFT camera, the stills only, non-video capable Lumix DMC-G1.
The Panasonic Lumix DMC-G10 is the sixth digital mirrorless interchangeable lens camera introduced that adheres to the Micro Four Thirds System (MFT) system design standard, and the fourth Panasonic model MFT camera. The G10 model was announced concurrently with its more capable sibling, the Panasonic Lumix DMC-G2, in March 2010.
The Olympus OM-D E-M5, announced in February 2012, is a Micro Four Thirds compact mirrorless interchangeable lens camera. In style and name it references the Olympus OM series of film SLR cameras, but it is not an SLR camera. The successor is the Olympus OM-D E-M5 Mark II.
The Sony Cyber-shot DSC-RX100 series is a high-end compact camera part of the wider Sony RX series. It started with the DSC-RX100, announced on 6 June 2012, and is part of the Cyber-shot RX line of digital cameras made by Sony. Seven annual generations have been released so far until 2019, all equipped with a one-inch 20-Megapixel image sensor and rotary knob around the lens. Filming at up to 1080p at 60fps is supported by the first three generations, the third additionally with 720p at 120fps, and up to 2160p (4K) at 30fps and 1080p at 120fps high frame rate video since the fourth.
The Olympus PEN E-PL5, announced on September 17, 2012 is Olympus Corporation's tenth camera that adheres to the Micro Four Thirds (MFT) system design standard. The E-PL5 succeeds the Olympus PEN E-PL3, and was announced in concert with one other model, the Olympus PEN E-PM2.
The Olympus OM-D E-M1 Micro Four Thirds is a compact mirrorless interchangeable-lens camera introduced on September 10, 2013. It has built-in on sensor phase detection.
The Olympus PEN E-P5 is a mirrorless interchangeable-lens camera in the micro four thirds system released in October 2013. This is, despite its number, the fourth model in the PEN E-P range. It remained the latest model in the E-P series until the introduction of the E-P7 in the summer of 2021. It includes the same 16 MP sensor as the Olympus OM-D E-M5. The E-P5 comes in three colour schemes; black, silver and white.
The Olympus OM-D E-M10 is a third model in the OM-D series of compact, mirrorless, interchangeable-lens cameras. It is of the Micro Four Thirds type that was introduced in January 2014.
The Olympus OM-D E-M5 Mark II is a digital interchangeable-lens camera announced in February 2015. It features a new 40-megapixel high-resolution mode that uses sensor shift to generate overlapping 16-megapixel images to then compute a 40-megapixel composite. It is the successor of the Olympus OM-D E-M5. Compared to that earlier model from 2012 and flagship OM-D E-M1 released in 2013, both of which are claimed to have 4 f-stops of shake compensation when shooting handheld, Olympus claims the OM-D E-M5 II can compensate 5 f-stops.
The Olympus OM-D E-M10 Mark II is a digital mirrorless system camera announced by Olympus Corporation on August 25, 2015.
The Olympus OM-D series is a series of Micro Four-Thirds digital Mirrorless Interchangeable Lens Cameras started by Olympus Corporation. Olympus's camera division was acquired by Japan Industrial Partners in 2021 and they will continue the OM-D series in the future.
The Olympus PEN-F is a mirrorless interchangeable-lens camera in the Micro Four Thirds system, released in 2016. It is the part of the digital PEN series. The PEN-F pays tribute to the similarly named PEN F half-frame 35mm film SLR camera from 1963.
The Olympus OM-D E-M1 Mark II is a digital mirrorless interchangeable-lens camera released by Olympus Corporation in December 2016. It replaced the Olympus OM-D E-M1, which was introduced in 2013.
Pixel shift is a method in digital cameras for producing a super resolution image. The method works by taking several images, after each such capture moving ("shifting") the sensor to a new position. In digital colour cameras that employ pixel shift, this avoids a major limitation inherent in using Bayer pattern for obtaining colour, and instead produces an image with increased colour resolution and, assuming a static subject or additional computational steps, an image free of colour moiré. Taking this idea further, sub-pixel shifting may increase the resolution of the final image beyond that suggested by the specified resolution of the image sensor.
The Olympus OM-D E-M10 Mark IV is the fourth iteration of the entry-level model in the OM-D series of mirrorless interchangeable-lens cameras produced by Olympus. The camera utilizes the micro four-thirds system and was announced on August 4, 2020, and launched on September 18 of the same year.
The Olympus OM-D E-M1 Mark III is the third iteration of the flagship camera in the series of OM-D mirrorless interchangeable-lens cameras produced by Olympus on the Micro Four-Thirds system. Released on February 28, 2020, it replaced the Olympus OM-D E-M1 Mark II.
