An extreme telephoto lens with an effective focal length of 400mm or longer and most commonly used by sports, wildlife and press photographers. These lenses are big, heavy and expensive but provide high levels of magnification not possible with ordinary lenses. Some consumer-orientated ‘bridge’ and ‘travel’ cameras have very long zoom ranges that fit into […]
Sony is best known as a giant electronics manufacturer making devices across a range of markets, but its camera division is doing especially well. The market for compact point and shoot cameras has fallen, but Sony is doing very well with its professionally-orientated full-frame A7 series and A9 cameras. It also makes a continually expanding […]
This is the distance between the mounting plate on a camera that takes interchangeable lenses and the sensor itself. Mirrorless cameras have a shorter flange distance because there’s no mirror inside the body, and this makes the cameras slimmer. DSLRs have a longer flange distance because there needs to be space inside the body for […]
In principle, you can’t mix and match different types and brands of lenses with different camera bodies. Each camera maker uses its own bespoke lens mount and different mechanical and electronic connections between the camera body and lens. However, it’s often possible to make lenses fit different brands and types of bodies with lens adaptors. […]
A twist-lock mechanism used almost universally for mounting lenses on camera bodies. You line up two dots, one on the lens barrel and one on the camera body and insert the lens, then twist the lens in the mount until it locks into place. The lens is released again by pressing a button on the […]
Company which champions old, analog cameras, outdated or cross-processed film and relaunched classic lens designs. Lomography products are known for their expense, sometimes makeshift construction and general unpredictability, but also revered by their fans for these very reasons (well, probably not the expense), because they introduce the kind of randomness, unexpectedness and engagement lost in […]
Billingham is a prestige camera bag maker in the UK’s West Midlands. It produces traditionally-styled canvas or FibreNyte material bags with brass fittings, leather straps and great attention to detail. Despite the traditional appearance, Billingham bags are designed for modern cameras and users, and owners hold them in high regard.
LUT stands for ‘lookup table’. Essentially, it takes the colours in an image and remaps them on to new ones. It really is a table consisting of a large grid of colour swatches and how they should be adjusted in the converted images. Its closest equivalent is the device profiles used in colour management systems, […]
The video equivalent of the image-enhancement stills photographers carry out on their images. Videographers ‘grade’ video to match the colours and exposures between clips, to create a certain ‘look’ or to edit video shot in a ‘log’ mode for extra dynamic range.
Extended dynamic range movie mode introduced by Fujifilm to handle high-contrast lighting, extending dynamic range by 200% or 400%. Other higher-end movie cameras have a similar feature. It produces flat-looking footage but with extended data in the shadow and highlight areas and the idea is that you process the video later on a computer (grading) […]
Also known as battery grips, these are accessories that attach to the bottom of some DSLRs or mirrorless cameras to offer extended battery life and, usually, a duplicate set of controls to make the camera suitable for extended use in portrait (vertical) mode. In some cases, a battery grip may also increase the continuous shooting […]
An image distortion effect caused by the way camera shutters operate at very high shutter speeds. Beyond a certain speed, focal plane shutters, as used in most interchangeable lens cameras, change the way they work. Instead of exposing the whole sensor at once, they expose it in a narrow strip between two shutter curtains passing […]
An advanced kind of electronic shutter that can capture the entire image area at once, instead of scanning it strip by strip. This should eliminate the rolling shutter effect usually associated with electronic shutters and make them much more effective for capturing moving subjects. It does, however, require advanced sensor technology, especially in larger sensor […]
The traditional form of camera shutter, a physical device which blocks light from the sensor until the moment you press the shutter release, then opens to expose the sensor for the required amount of time before it closes again. Mechanical shutters are either focal plane types, just in front of the sensor, or in-lens ‘leaf’ […]
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.
This is the lens mount for Fujifilm’s X-series mirrorless cameras. These include the Fujifilm X-T2, X-H1, X-E3 and others. Any X-mount lenses can be used on any X-mount camera, though note that Fujifilm’s medium format GFX 50S uses a different mount and different lenses.
These are designed specifically for holding camera gear, with a padded interior separated into compartments with padded dividers which you can usually rearrange to suit your kit. Camera bags fall into a handful of main types: Backpacks are the largest and designed for carrying a large quantity of kit over some distance. They’re also good […]
As the name suggests, this is a lens particular suited to portraiture by virtue of its focal length and a fast maximum aperture. In portrait photography, you get better facial perspective if you stand back a little from the subject. This means you need to use a slightly longer focal length than usual to fill […]
This is an interchangeable lens camera where you see an optical image of what the lens sees in the viewfinder. They do this using a mirror inside the body that reflects the image seen by the lens up into the viewfinder. When you take a picture, the mirror flips up out of the way so […]
Dual Pixel CMOS AF is an autofocus technology developed by Canon that aims to deliver the speed and responsiveness of phase detection autofocus using only the camera sensor and not a separate phase detection sensor. This has many advantages for mirrorless cameras and DSLRs being used in live view mode. Effectively, the photosites on Canon’s […]
