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

10. Same level of weather sealing as D850

Various seals around the bodies provide the new cameras with the same level of weather sealing as the company’s D850 DSLR, and dust- and drip protection extends to the three new lenses that have been announced at the same time.

11. Fn1 and Fn2 buttons

The front plate offers three buttons: one to release the lens from the body and two Fn buttons: Fn1 and Fn2. Much like on the DSLRs that have the same setup, these two buttons can be programmed to access a setting of the user’s choosing, such as white balance, Picture Control and Image Size.

12. Mode dial

The cameras’ mode dials have the standard Program, Aperture Priority, Shutter Priority and Manual exposure options, alongside Auto and customisable U1, U2, and U3 settings. They also follow certain Nikon DSLRs in having a locking button in their centre, which keeps them in place.

13 Twin command dials

With one command dial embedded into the new cameras‘ grip and another on the top plate for the thumb to access, the new bodies provide the same kind of control as enthusiast- and professional-level DSLR with regards to adjusting camera settings.

14. Sensor-based Vibration Reduction

Vibration Reduction is something we normally get in Nikon’s lenses, but here we get it at the sensor. This system works over five directions – yaw, pitch, roll, X and Y – and is said to deliver up to 5 stops of correction. The system is offered in Normal and Sport modes, the latter for moving subjects.

15. VR system works with VR lenses

Not only does the VR system bring stabilisation to a number of older, unstabilised lenses that are mounted with the FTZ adapter, but it will also work with lenses that are designed with the equivalent technology, with the two systems working together.

16. Magnesium alloy panels

The top, front and back plates of the new cameras are built from magnesium alloy for rigidity and light weight, the same material used in many of the company’s DSLRs.

17. Shutter rated to 200K actuations

The mechanical shutters inside the two cameras have been rated to 200k actuations, which is a measure of how long Nikon’s shutter expected it to last. This is the same as the company’s D810 DSLR.

18. Speedlights through hot shoe

Flash user? Good news. The hot shoe allows you to mount the same Speedlight flash units that are compatible with the company’s DSLRs, so there’s no need to wait for these to be developed specifically for the system.

19. Lighter than a DSLR

At a weight of 585g for the body, and 675g with a battery and memory card loaded, each camera weighs significantly less than the equivalent DSLR, the Nikon D850, which comes in at 1,005g with its card and battery in place.

20 Substantial grip

Although Nikon has sought to make the bodies compact, their grips are somewhat substantial and have been designed to offer as secure and comfortable a hold as possible. Those coming from DSLRs should find this to be particularly welcome, especially if they use long or weighty lenses.
