Description

Open-air helping hand support

Technical Field

The invention relates to the technical field of photography and videography periphery, in particular to a field power-assisted support.

Background

Single Lens Reflex Camera (Single Lens Reflex Camera, abbreviated as SLR Camera) is also called Single Lens Reflex Camera. The single lens is used, light irradiates a reflector through the single lens, and the reflector is used for framing through reflection.

By "single lens" is meant that the photographic exposure optical path and the viewfinder optical path share a single lens, unlike a single lens for the viewfinder optical path of a paraxial camera or a dual-lens inverter. "reflective" means that a planar mirror in the camera separates two optical paths: when viewing, the reflector falls down, and the light rays of the lens are reflected to the pentaprism and then to the viewing window; when shooting, the reflector is quickly lifted, and light can irradiate on a film or a photosensitive element CMOS or CCD.

The bigger single lens that reflects on the market at present, especially long focus lens, if the focus is 600, the minimum light ring is the camera lens of 4.0, and it is very big, also very heavy, carries inconveniently, all needs the tripod to support when shooing, and it is motionless to take alone to hand, shoots very inconveniently, seriously influences and shoots and make a video recording.

However, in some specific environments such as ships, cars, etc., it is quite troublesome to carry a tripod, and when some scenes need to be captured, the moment is likely to be missed by unfolding the tripod and installing the single lens reflex camera.

Furthermore, when the tripod is used on a ship or a car, the ship and the car are shaken by nature, so that the tripod loses its stable function and cannot play a role in anti-shake.
