In photography, shutter lag is the delay between triggering the shutter and when the photograph is actually recorded. This is a common problem in the photography of fast-moving objects or people in motion. The term narrowly refers only to shutter effects, but more broadly refers to all lag between when the shutter button is pressed and when the photo is taken, including metering and focus lag.

Sony α, is a camera system introduced on 5 June 2006. It uses and expands upon Konica Minolta camera technologies, including the Minolta AF SLR lens mount, whose assets were acquired by Sony after the end of Konica Minolta's photography operations in early 2006. Sony also has an 11.08% ownership stake in Japanese lens manufacturer Tamron, which is known to have partnered with Konica Minolta and Sony in the design and manufacture of many zoom lenses.
A pellicle mirror is an ultra-thin, ultra-lightweight semi-transparent mirror employed in the light path of an optical instrument, splitting the light beam into two separate beams, both of reduced light intensity. Splitting the beam allows its use for multiple purposes simultaneously. The thinness of the mirror practically eliminates beam or image doubling due to a non-coincident weak second reflection from the nominally non-reflecting surface, a problem with mirror-type beam splitters.
The Sony α700 (DSLR-A700) was the second model launched in the Sony α series of APS-C sensor digital single-lens reflex cameras, following the α100, with several improvements over the latter. Some of the camera's technology was inspired by the former Konica Minolta Maxxum 7D, such as the man-machine command interface/commands, LCD menus, viewfinder, and lens mount.
BIONZ is an image processor used in Sony digital cameras.
Announced by Sony on August 24, 2011 the Sony α77 was the flagship for Sony's midrange Alpha SLT camera line.
The Sony α37 or Sony Alpha 37 is a single-lens reflex style digital camera that replaced the SLT-A35 in 2012. However, the Alpha 37 camera features an electronic viewfinder and a translucent mirror. The main advantage of a translucent mirror is that it needn't flip up out of the way when taking a picture in order to expose the sensor, but the camera can focus and capture images simultaneously. Also the viewfinder can be used while video recording or stills/video playback, which is useful for example in bright sunlight. The camera's 15-point autofocus system can be set to single, continuous or automatic and is arranged towards the centre. The 7 fps burst mode is available only in "speed priority" mode but can reach up to 5.5 fps burst rate in combination with any other settings. The A37 is compatible with Sony Bravia Televisions.
The Sony Alpha 99 was announced by Sony on September 12, 2012. It was the flagship Sony DSLR camera and of the Sony Alpha SLT line until late 2016 when it was replaced by the Sony α99 II.
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 and α7S are three closely related full-frame mirrorless interchangeable-lens cameras. The first two were announced on 16 October 2013 and the third on 6 April 2014. Externally they are identical except for the model number. They are Sony’s first full-frame mirrorless interchangeable lens cameras and share the E-mount with the company’s smaller sensor NEX series.
Announced by Sony on August 24, 2011 and launched alongside its brother the Sony Alpha 77, the Sony Alpha 65 is the top-tier for Sony's midrange Alpha SLT camera line.
The Sony α58, Sony Alpha 58 also known as Sony A58 is a mid-range single-lens reflex digital camera from Sony's Alpha SLT camera line, introduced in 2013.
The Sony Alpha 77 II (ILCA-77M2), stylized as the Sony α77 II, is an interchangeable-lens camera aimed at the advanced amateur. It replaced the Sony Alpha 77 model in June 2014. It is similar in design to its predecessor, including the use of a SLT transparent mirror and electronic viewfinder.
The Sony Alpha 68 or Sony ILCA-68(named internally; ILCA- although coming from the "Sony SLT camera" line of cameras) is a mid-size DSLT camera announced by Sony on November 5, 2015 and available for purchase starting April 2016 (US) and March 2016 (Europe). Sony markets it as having "4D FOCUS for fast, accurate tracking autofocus".
The Sony α99 II is the flagship Sony DSLR and continues the Sony α SLT line of Sony A-mount camera bodies. It was first announced by Sony on September 19, 2016 at photokina 2016 and replaced the original Sony α99. Its single-lens translucent design allows for faster focusing and shooting than other DSLRs. Consequently, at 12 FPS, it can shoot roughly twice as fast in continuous burst mode as competing models as of 2016. The α99 II also features best-in-class low-light autofocus.
