This is a new autofocus technology being introduced by Nikon in its consumer-level lenses. It used different autofocus actuators to its existing AF-S (Supersonic Wave) lenses. The AF-P system uses stepper motors for a fast, quiet and smooth autofocus action that’s especially well suited to video, where you don’t want fast, sharp focus movements or audible motors that you can hear in the video.
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.
Nikon’s name for its ‘program shift’ control, where you can change the balance of lens aperture and shutter speed without having to leave the program AE mode – you simply turn the command dial until the camera displays the lens aperture or shutter speed you want.
Nikon’s own brand name for the image processors used in its digital cameras. More powerful processors are needed for higher-resolution sensors and faster continuous shooting speeds, and play a part in noise reduction at high ISOs and image quality generally.
