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.

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.
