An evolution of the DxO Optics Pro software which adds local adjustments – the ability to modify selected areas of a photo only – to DxO Optics Pro, amongst other enhancements. DxO PhotoLab is a standalone program for Mac or PC and its speciality is high-quality raw file processing and automatic lens corrections and optimisation. It comes in a lower cost Essentials and more expensive Elite version.
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 this category, though the small size of the sensor and limited optical quality of the lenses stops them being taken seriously alongside professional cameras.
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 range of high-end professional lenses.
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 the mirror that this design gets its name from. This makes DSLR bodies thicker. This difference in flange distances means that it’s sometimes possible to use lens adaptors to fit lenses of a different type, brand or lens mount to a camera. This generally works one way only – you can mount a lens with a longer flange distance (e.g. a DSLR or old film SLR lens) on a camera with a shorter flange distance (e.g. a mirrorless camera) but not the other way round.
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. These are usually from third-party makers and designed for users who don’t mind a few compromises in camera functions. For example, you may lose autofocus functions and have to use manual focus only, and it’s likely that you’ll have to use manual exposure and lens aperture control rather than the camera’s full range of exposure controls.
