Nikon Corporation is a Japanese optics and photographic equipment manufacturer. Nikon's products include cameras, camera lenses, binoculars, microscopes, ophthalmic lenses, measurement instruments, rifle scopes, spotting scopes, and equipment related to semiconductor fabrication, such as steppers used in the photolithography steps of such manufacturing. Nikon is the world's second largest manufacturer of such equipment.
An autofocus (AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types.
A digital single-lens reflex camera is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor.
Sigma Corporation is a Japanese company, manufacturing cameras, lenses, flashes and other photographic accessories. All Sigma products are produced in the company's own Aizu factory in Bandai, Fukushima, Japan. Although Sigma produces several camera models, the company is best known for producing high-quality lenses and other accessories that are compatible with the cameras produced by other companies.
A full-frame DSLR is a digital single-lens reflex camera (DSLR) with a 35 mm image sensor format. Historically, 35 mm was one of the standard film formats, alongside larger ones, such as medium format and large format. The full-frame DSLR is in contrast to full-frame mirrorless interchangeable-lens cameras, and DSLR and mirrorless cameras with smaller sensors, much smaller than a full 35 mm frame. Many digital cameras, both compact and SLR models, use a smaller-than-35 mm frame as it is easier and cheaper to manufacture imaging sensors at a smaller size. Historically, the earliest digital SLR models, such as the Nikon NASA F4 or Kodak DCS 100, also used a smaller sensor.
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.
A mirrorless camera is a digital camera which, in contrast to DSLRs, does not use a mirror in order to ensure that the image presented to the photographer through the viewfinder is identical to that taken by the camera. They have come to replace DSLRs, which have historically dominated interchangeable lens cameras. Other terms include electronic viewfinder interchangeable lens (EVIL) cameras and compact system cameras (CSCs).
A back-illuminated sensor, also known as backside illumination (BI) sensor, is a type of digital image sensor that uses a novel arrangement of the imaging elements to increase the amount of light captured and thereby improve low-light performance.
Single-lens translucent (SLT) is a Sony proprietary designation for Sony Alpha cameras which employ a pellicle mirror, electronic viewfinder, and phase-detection autofocus system. They employ the same Minolta A-mount as Sony Alpha DSLR cameras.
The Sony α7, α7R, α7S and α7C are four closely related families of full-frame mirrorless interchangeable-lens cameras. The first two were announced in October 2013, the third in April 2014 and the fourth in September 2020. They are Sony's first full-frame mirrorless interchangeable lens cameras and share the E-mount with the company's smaller sensor NEX series.
Nikon Z-mount is an interchangeable lens mount developed by Nikon for its mirrorless digital cameras. In late 2018, Nikon released two cameras that use this mount, the full-frame Nikon Z7 and Nikon Z6. In late 2019 Nikon announced their first Z-mount camera with an APS-C sensor, the Nikon Z50. In July 2020 the entry-level full-frame Z5 was introduced. In October 2020, Nikon announced the Nikon Z6II and Nikon Z7II, which succeed the Z6 and Z7, respectively. The APS-C lineup was expanded in July 2021, with the introduction of the retro styled Nikon Zfc, and in October 2021, Nikon unveiled the Nikon Z9, which effectively succeeds the brand's flagship D6 DSLR. The APS-C lineup was further expanded with the Nikon Z30, announced at the end of June 2022. The Nikon Z6III was announced in June 2024. In November 2024, Nikon announced the Z50II, the first APS-C camera to use the Expeed 7 processor introduced with the Z9.
The Nikon Z7 is a 45.7 megapixel full-frame mirrorless interchangeable-lens camera produced by Nikon. The camera was officially announced on August 23, 2018, for release in September 2018. It was the first camera to use Nikon's new Z-mount system; the second model, released in November 2018, was the 24.5 megapixel Nikon Z 6.
The Canon EOS R is the first full-frame mirrorless interchangeable-lens camera (MILC) produced by Canon. It was announced days after Nikon's first full-frame MILC, the Nikon Z 7, and five years after Sony's first, and was released in October 2018. The camera is the first of Canon's new EOS R system, and the first to use the RF lens mount. The "R" stands for "Reimagine optical excellence".
The Fujifilm X-T4 is a mirrorless interchangeable-lens digital camera announced on February 25, 2020. It has a backside-illuminated X-Trans CMOS 4 APS-C sensor and an X-Processor 4 quad core processor and uses the Fujifilm X-mount. The X-T4 is a weather-resistant camera equipped with a higher-capacity battery designed to last longer than the X-T3. It is the successor to 2018's X-T3, which is a little smaller and lighter.
The Nikon Z5 is a full-frame mirrorless interchangeable-lens camera produced by Nikon. The camera was officially announced on July 21, 2020, at the price of US$1,399.00. It is an entry-level full-frame camera that uses Nikon's Z-mount system.
The Fujifilm GFX100S is a mirrorless medium format camera produced by Fujifilm with Fujifilm G-mount. It is a smaller version of the 2019 GFX100 camera. The camera was announced by the corporation on January 27, 2021 at the X Summit Global 2021 together with the X-E4. Sales began in March 2021.
