99 things you need to know about Nikon's full-frame mirrorless camera system

31. Hybrid AF setup

The new cameras combine phase-detect AF pixels on the sensor with contrast-detect focusing, with automatic switching between the two to suit the conditions at hand.

32. Wide coverage

One of the advantages of the new focusing system is that it can cover 90% of the horizontal and vertical stretch of the frame. By comparison, the flagship D5 DSLR only offers 55% coverage across its horizontal dimension, which makes it more difficult to focus on peripheral subjects. 

33. Focus peaking

Focus peaking, which allows you to assess the areas of highest contrast when manual focusing a lens by way of a highlight, is offered on the new models. This can have both its threshold and colour adjusted, the latter being useful when it comes to photographing a subject that would ordinarily be the same colour as the highlight. Red, yellow, blue and white options are available.

34. Sub-selector

The camera’s AF point can be quickly and conveniently adjusted using a joystick-style control – or ‘sub-selector’ in Nikon parlance – on the back of the camera. This feature has previously graced a number of the company’s DSLRs, such as the D500 and D850.

35. AF-ON button*

A staple of higher-end Nikon DSLRs, the AF-ON button allows you to focus separately from the shutter-release button. This is great in situations where the autofocusing system may be thrown, or when shooting with obstacles constantly passing in the way of the main subject.

36. Focus Shift Shooting*

The Focus Shift Shooting mode allows you to capture a series of images with different depths of field, which can then be subsequently merged together into a single composite file using third-party software. A new feature here is monochrome preview of the focused areas, which helps you to work out whether your stacking will be successful.

37. Auto AF keeps track of faces*

When set to the Auto Area AF mode, the cameras are able to keep a lock on subject’s faces as they move around the scene. This is particularly useful for video recording, where subject or camera movement may encourage the camera to lose focus on the main subject.

38. Lenses designed with video in mind

Nikon states that it’s designed the new lenses to minimise focus breathing, which is where the angle of view slightly changes as focus is adjusted. With this, Nikon claims, it can achieve “supremely natural movie expression with a minimized sense of incongruity.”

39. You can adjust AF speed…*

When shooting videos, sometimes you don’t want autofocus to be too fast as it can appear unprofessional. Fortunately, the cameras’ response can be adjusted over 11 steps through the Custom Menu for smoother transitions.

40. And also tracking sensitivity

Likewise, the sensitivity of the tracking system can also be adjusted, so that the cameras know whether to move quickly from one subject to the next or whether to focus on adhering to a single subject.
