Operation & Controls

The D750 is an incredibly customizable camera. It's not just the number of buttons whose functions can be reassigned, but the wide variety of settings that you can choose from - down to a specific item in a sub-menu. Some of the items you can tweak are commonplace, such as which dial adjusts shutter speed or aperture, and which way the dials turn. Once you start getting into the buttons, your choices can be a lot more complex.

There are a total of five buttons on the D750 which can be customized. If you have the grip attached or are using a wireless, there's one for each of those as well. Four of the five buttons on the camera body can have separate assignments when in movie mode, as well. Let's take a quick look at what each of the five buttons on the D750 can do:

The OK button can be customized in shooting, live view, and playback modes.

One notable thing the OK button can do is zoom to 100% in playback mode - something not normally found on cameras in this class.

If you want to disable the button in any of these modes, you can do so.

Here's what you can assign for viewfinder and live view shooting as well as playback mode:

Shooting mode

• Select center focus point
• Highlight active focus point
• None

Live view mode

• Select center focus pt
• Zoom on/off
• Low magnification (50%)
• 1:1 (100%)
• High magnification (200%)
• None

Playback mode

• Thumbnail on/off
• View histograms
• Zoom on/off
• Low magnification (50%)
• 1:1 (100%)
• High magnification (200%)
• Choose slot and folder

On the front of the camera are a pair of buttons, one for DOF preview and the other for doing whatever you'd like. Both have the same settings to choose from.

The Pv (DOF preview) and Fn (function) buttons can be customized in a myriad of ways.

The options available for this pair of buttons include:

• DOF preview
• FV lock
• AE/AF lock
• AE lock only
• AE lock (hold)
• AF lock only
• AF-On
• Flash off
• Bracketing burst
• +NEF (RAW)
• Matrix metering
• Center-weighted metering
• Spot metering
• Highlight-weighted metering
• Viewfinder grid display
• Viewfinder virtual horizon
• My Menu
• Access top item in My Menu
• Playback
• None

By holding down either of these buttons and rotating the command dials you can choose an image area, adjust the aperture in 1EV increments (regardless of how you have it set up), choose the non-CPU lens number, turn on Active D-Lighting or HDR, and activate exposure delay mode.

The AE-L/AF-L button's function can be defined in the following ways:

• AE/AF lock
• AE lock only
• AE lock (hold)
• AF lock only
• AF-On
• FV lock
• None

By holding down the AE-L/AF-L button and rotating the command dial you can also choose the image area (FX, 1.2x, DX), set the non-CPU lens number, or nothing at all.

By holding down the red movie recording button and rotating the command dials you can quickly adjust the white balance, ISO, or image area. Naturally, 'nothing' is an option, as well.

When the camera is in video mode, the Fn, Pv, AE-L/AF-L, and shutter release buttons can all have their functions customized. The Fn button can handle AF-On duties, while you can select whether the shutter release button handles stills or videos.

The preview (Pv) and AE-L/AF-L buttons have the same options, which include:

• Power aperture
• Index marking
• View photo shooting info
• AE/AF lock
• AE lock only

• AE lock (hold)
• AF lock only
• AF-On
• None

Menus

The D750's menu system is unsurprisingly similar to what you'll find on every other modern Nikon DSLR. It's split up into seven 'tabs', covering playback, photo shooting, video, custom settings, setup, retouch, and 'My Menu'.

There are seven categories of custom settings, ranging from A to G. Items are logically placed and the color coding makes it easy to find what you're looking for. If you're confused about any item in particular you can press the '?' button to the left of the display for a brief explanation.

The My Menu feature can do one of two things. By default, it displays the last settings you adjusted. As its name implies, you can also put in whatever menu item you want in the order of your choosing. You can customize one of the buttons on the camera to jump directly to the top-most item in the menu, which can be the setting which the user accesses the most often.
