Features
The camera's appearance was unique, as it lacked the ubiquitous SLR pentaprism "hump". Instead, a Porro prism system was used; it fitted sideways within the camera, with a sideways-swinging mirror, and located the viewfinder eyepiece to the left (seen from behind) relative to the lens centerline. The body was largely of ABS plastic over a metal frame; the lens mount was metal, and there was a metal covered area on the left top of the camera. This area also contained the onboard flash, which popped up and forward at the touch of a button. The onboard flash popup mechanism is manual. In low light scenarios the flash will not pop up automatically but the photographer must press the button and pop it up before taking the photo.
The E-300 uses Olympus' patented Supersonic Wave Filter dust reduction system to shake dust from the sensor during startup and when requested by the user; this largely eliminates the problem of dust accumulation on the surface of the image sensor.
The E-300 was replaced by the Olympus E-330, a similar model with live preview, in January 2006.
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.
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 Canon EOS 10D is a discontinued 6.3-megapixel semi-professional digital SLR camera, initially announced on 27 February 2003. It replaced the EOS D60, which is also a 6.3-megapixel digital SLR camera. It was succeeded by the EOS 20D in August 2004.
Canon EOS is an autofocus single-lens reflex camera (SLR) and mirrorless camera series produced by Canon Inc. Introduced in 1987 with the Canon EOS 650, all EOS cameras used 35 mm film until October 1996 when the EOS IX was released using the new and short-lived APS film. In 2000, the D30 was announced, as the first digital SLR designed and produced entirely by Canon. Since 2005, all newly announced EOS cameras have used digital image sensors rather than film. The EOS line is still in production as Canon's current digital SLR (DSLR) range, and, with the 2012 introduction of the Canon EOS M, Canon's mirrorless interchangeable-lens camera (MILC) system. In 2018 the system was further extended with the introduction of the EOS R camera, Canon's first full frame mirrorless interchangeable lens system.
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-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.
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 Digilux 3 is a digital single-lens reflex camera introduced by Leica on 14 September 2006. The Digilux 3 and the Panasonic Lumix DMC-L1 are similar specification cameras, using the Four Thirds standard lens mount and featuring a 7.5 Megapixels live view N-MOS sensor, but the Digilux 3 has modified firmware including DNG output. Both the Panasonic and Digilux 3 cameras come standard with the same interchangeable Leica Elmarit 14–50 mm f/2.8–3.5 optically image-stabilized zoom lens. The Leica D system includes also the Leica Summilux 25 mm f/1.4 lens.
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 Canon EOS 40D is a 10.1-megapixel semi-professional digital single-lens reflex camera. It was initially announced on 20 August 2007 and was released at the end of that month. It is the successor of the Canon EOS 30D, and is succeeded by the EOS 50D. It can accept EF and EF-S lenses. Like its predecessor, it uses an APS-C sized image sensor, resulting in a 1.6x field of view crop factor.
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.
The Olympus E-3 was until 2010 Olympus Corporation's flagship camera, positioned as a professional DSLR camera. It is the successor to the Olympus E-1, which was launched in November 2003. The E-3, originally codenamed Olympus E-P1, was announced on 17 October 2007. The E-3, like the other cameras in the Olympus E-series, conforms to the Four Thirds system. It was succeeded in 2010 by the Olympus E-5 professional DSLR flagship camera.
The Olympus E-420 is a 10 megapixel digital single-lens reflex (DSLR) camera made by Olympus. The camera conforms to the Four Thirds System standard, and together with its siblings in the E-4XX series, it is marketed as the smallest DSLR in the world.
The Olympus E-520 is a 10 megapixel digital single-lens reflex (DSLR) camera.
This article discusses the cameras – mainly 35 mm SLRs – manufactured by Pentax Ricoh Imaging Corp. and its predecessors, Pentax Corporation and Asahi Optical Co., Ltd.. Pentax must not be confused with Pentax 6x7 or Pentax 67 which are 120 medium format 6x7cm film cameras.
The Canon EOS 500D is a 15-megapixel entry-level digital single-lens reflex camera, announced by Canon on 25 March 2009. It was released in May 2009. It is known as the EOS Kiss X3 in Japan, and as the EOS Rebel T1i in North America. It continues the Rebel line of mid-range DSLR cameras, is placed by Canon as the next model up from the EOS 450D, and has been superseded by the EOS 550D (T2i).
The Olympus E-450 is a 10.0 megapixel digital single-lens reflex (DSLR) camera made by Olympus and conforming to the Four Thirds System standard. E-450 was announced in March 2009, and shipping started in May the same year. E-450 is similar in size to its siblings in the E-4XX series, marketed as the smallest DSLRs in the world.
The Panasonic Lumix DMC-G3 is a digital mirrorless interchangeable lens camera adhering to the joint Olympus and Panasonic Micro Four Thirds System (MFT) system design standard. The Panasonic Lumix DMC-G3 is the eighth Panasonic MFT camera introduced under the standard and the thirteenth model MFT camera introduced by either Olympus or Panasonic, as of the G3 product announcement date.
