Nikon's corrected D600 successor — 24.3MP full-frame with improved shutter and dual SD card slots.
The Nikon D610 was released in October 2013 as the replacement for the D600, which had suffered from a documented shutter mechanism issue causing oil and dust contamination on the sensor in early production units. The D610 addressed this with a revised shutter mechanism and added a quiet shutter mode. Specifications are nearly identical to the D600: a 24.3MP FX CMOS sensor, 39-point AF module, and 6fps burst rate. Dual SD UHS-I card slots provide redundancy and overflow.
The 24.3MP FX CMOS sensor pairs with the EXPEED 3 processor. The 39-point AF system provides 9 cross-type points for subject tracking. Burst shooting runs at 6fps. 1080p video records at up to 30fps. Dust and weather sealing is built throughout the magnesium alloy chassis. Battery life approximately 900 shots using the EN-EL15, body weight approximately 760g with battery and card, dual SD UHS-I card slots.
The D610's 24.3MP full-frame sensor at 760g was the lightest full-frame DSLR from Nikon at its price point, enabling full-frame image quality in a body lighter than the D810/D800 series. The dual SD card configuration — unusual for full-frame DSLRs of the era that typically used CompactFlash — keeps the accessory cost low. The 39-point AF module provides solid multi-subject tracking for portraits, events, and documentary work.
On the used market the D610 is very affordable for a 24.3MP full-frame DSLR. Condition checks: shutter count via EXIF, sensor for any residual oil contamination (the D610's revised shutter largely resolved the D600 issue), both SD slot contacts, and EN-EL15 battery health — shared with D800, D810, D750, and Z-series bodies. Compatible with all Nikon F-mount lenses.
