Short for ‘in-body image stabilisation’ and a term used by Fujifilm for its X-H1 pro mirrorless camera. In-body image stabilisers shift the camera sensor to counteract any camera movement during the exposure. It’s the first time Fujifilm has used in-body stabilisation, but it’s already used by Pentax, Panasonic, Sony and Olympus.
In video, a ‘rig’ is a harness, a camera mount, a gyroscopic stabiliser or any apparatus designed to make it easier to carry and use a video camera. A rig may also have mounting points for video lights and microphones.
Nikon’s name for its image stabilisation technology, as built into its DSLR lenses. Tiny gyroscopic sensors detect any camera movement during the exposure and instantly shift a group of internal lens elements to compensate and keep the image steady on the sensor.
A shutter speed fast enough to prevent camera shake during the exposure. Normally, it’s a second divided by the effective focal length of the lens, so for a 60mm lens a shutter speed of 1/60sec should be ‘safe’. The advent of image stabilisers, however, has made it possible to get sharp handheld shots at much […]
Image stabiliser which moves physical elements within the lens, or the sensor itself, to keep the image steady during the exposure. This is superior to ‘digital stabilizers’ which use image processing techniques to reduce blur, but which also lead to a loss in quality.
An option on more advanced DSLRs that flips the mirror up in advance of the exposure in order to give any vibrations from the mirror mechanism time to die down. It’s popular with fans of macro photography and some landscape photographers.
A mechanism that counteracts camera movement during the exposure. Lens-based stabilisers use a moving lens element, while sensor-based stabilisers move the sensor itself. Image stabilisers are used to get sharper telephoto shots and low-light shots without camera shake.
Any photography – obviously – where you’re holding the camera with your hands rather than using a tripod or some other form of camera support. It has special implications for night and low light photography where it’s important to use shutter speeds fast enough to prevent camera shake.
This is image blur caused by camera movement during the exposure. The longer the exposure (the slower the shutter speed), the more time there is for camera movement to take place. Any movement is also exaggerated with longer focal length lenses (telephotos). There is a simple way to estimate the risk of camera shake – […]
The latest kind of image stabilisation technology, where the camera’s sensor can be tilted or shifted on 5 axes to counter a much wider range and types of movement than regular lens-based image stabilisers, and it’s a particular advantage for video, where these additional movements can pose problems during handheld filming. 5-axis stabilisation used in […]
