Body Elements

All of the elements below - save for the mode dial - are identical to the D600.

The D610's viewfinder offers 100% coverage and 0.7x magnification, offering the same viewing experience as the considerably more expensive D800 and D4.

The small wheel at upper-right is a diopter adjustment for those of us who wear glasses.

The D610's mode dial has the usual selection of shooting options, including a pair of customizable 'user' spots. The button at the center locks the dial in its current position.

Under the dial is a switch that includes continuous shooting modes (including the new Quiet Continuous option), the 'standard' Quiet mode, Self-Timer and Mirror Lock-Up.

The D610 has a video capture mode, and just like the D800, it offers a direct movie shooting button for quick and easy movie capture once you're in video live view mode.
The D610's live view control is exactly the same as it is on the D600, and comprises of a live view activation button with a collar-type switch to move between still and movie live view modes. In movie mode the view on the LCD is cropped to preview the field of view captured during video shooting.
The D610 has two IR windows, on the front of the camera (shown here) and one the rear, which allow it to be triggered by Nikon's inexpensive ML-L3 wireless trigger.
The two buttons on the front of the camera (lower one shown here) can be assigned a wide range of different duties, including depth-of-field preview and engaging an on-screen/in-viewfinder electronic horizon.
Easy to miss, this tiny screw is the business-end of an in-camera AF motor which drives the autofocus in non-AF-S lenses. This makes the D610 significantly more compatible with Nikon and third-party legacy optics than DSLRs further down Nikon's lineup.
On the side of the camera you'll find its various sockets. A USB 2.0 socket shares space with an HDMI-out socket, a microphone socket and a headphone jack for monitoring audio in movie mode.
The D610 has twin memory card bays accommodating two SD cards with provision for simultaneous recording, as well as options for overflow or separate JPEG/Raw or still/video storage.
