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 digital imaging sensor.
Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm.
CineAlta cameras are a series of professional digital movie cameras produced by Sony that replicate many of the same features of 35mm film motion picture cameras.
A full-frame DSLR is a digital single-lens reflex camera (DSLR) with a 35 mm image sensor format. Historically, 35 mm was considered a small film format compared with medium format, large format and even larger.
In digital photography, the image sensor format is the shape and size of the image sensor.
Exmor is the name of a technology Sony implemented on some of their CMOS image sensors. It performs on-chip analog/digital signal conversion and two-step noise reduction in parallel on each column of the CMOS sensor.
BIONZ is a line of image processors used in Sony digital cameras.
The Micro Four Thirds system is a standard released by Olympus 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, Panasonic, Sharp, and Xiaomi. MFT lenses are produced by Cosina Voigtländer, DJI, Kowa, Kodak, Mitakon, Olympus, Panasonic, Samyang, Sharp, Sigma, SLR Magic, Tamron, Tokina, TTArtisan, Veydra, Xiaomi, Laowa, Yongnuo, Zonlai, Lensbaby, Kowa and 7artisans amongst others.
A mirrorless interchangeable-lens camera (MILC) or simply mirrorless camera, also called digital single lens mirrorless (DSLM), is a photo camera featuring a single, removable lens and a digital display. The camera does not have a reflex mirror or optical viewfinder like a digital single-lens reflex (DSLR) camera. Many mirrorless cameras retain a mechanical shutter. Like a DSLR, a mirrorless camera accepts any of a series of interchangeable lenses compatible with its lens mount.
The E-mount is a lens mount designed by Sony for their NEX and ILCE series of camcorders and mirrorless cameras. The E-mount supplements Sony's A-mount, allowing the company to develop more compact imaging devices while maintaining compatibility with 35mm sensors. E-mount achieves this by:
The Sony α NEX-5 is a digital camera launched on 11 May 2010. It is a mirrorless interchangeable lens camera with the body size of a larger model fairly compact point-and-shoot camera with a larger sensor size (APS-C) comparable to that of some digital single-lens reflex cameras. Its major competitors in the market are the cameras based on the micro 4/3 standard created by Panasonic and Olympus, and a few low end Canon, Nikon, and even Sony α DSLRs. The NEX-5 shoots 14.2 megapixel stills and has a 7 frame/s continuous shotmode. It has the capability to shoot 1920×1080i at 60 frame/s in AVCHD or 1440×1080p at 30 frame/s in MPEG4. The NEX-5 was replaced by the 16 megapixel NEX-5N in August 2011.
The Panasonic Lumix DMC-G2 is a digital mirrorless interchangeable lens camera adhering to the Olympus and Panasonic developed Micro Four Thirds System (MFT) system design standard. It was announced in March 2010 along with a lesser featured Panasonic Lumix DMC-G10.
Panasonic Lumix DMC-GF3 is the eighth camera in Panasonic's Lumix G-series adhering to the Micro Four Thirds System (MFT) design standard, and was announced in June 2011.
The Sony α NEX-7 is a digital camera announced 24 August 2011 by Sony. It is a mirrorless interchangeable lens camera and as such inherits a smaller body form factor than a traditional digital single-lens reflex camera, while still retaining the sensor size and features of an APS-C-sized model. It is targeted at experienced users, enthusiasts and professionals. It is replaced by the ILCE-6000 (α6000).
In Sony digital cameras, the acronym ILCE stands for "Interchangeable Lens Camera with E-mount". In August 2013, Sony announced the first model of the ILCE mirrorless camera with E-mount, electronic viewfinder, contrast-detection autofocus and Multi Interface Shoe, the ILCE-3000. In October 2013, two full-frame E-mount cameras were announced, the ILCE-7 and ILCE-7R.
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.
The Sony α6000 is a digital camera announced 12 February 2014. It is a mirrorless interchangeable lens camera (MILC), which has a smaller body form factor than a traditional DSLR while retaining the sensor size and features of an APS-C-sized model. It is targeted at professionals, experienced users, and enthusiasts. It replaced the NEX-6 and NEX-7. Review websites note that although the α6000 uses a 24 MP sensor like the Sony NEX-7, the Sony α6000 can also be seen as more of a replacement of the Sony NEX-6. In the Firmware version 1.10, an android subsystem was added. The sub system was used to run Sony's apps.
The Sigma 30mm F2.8 EX DN is a standard prime lens for Sony E and Micro Four-Thirds mounts, announced by Sigma in January 2012. Along with the Sigma 19mm F2.8 EX DN, it was part of the first release of Sigma lenses for compact interchangeable lens cameras, and hence the inception of the "DN" line, created by Sigma to cater to these cameras, an offering that in January 2013 was expanded with another lens, the Sigma 60mm f/2.8 DN Art.
