Nikon's corrected D600 successor — 24.3MP full-frame with improved shutter and dual SD card slots.
The Nikon D610 (2013) quietly replaced the D600, which suffered oil/dust spotting from its shutter mechanism. The D610 addressed this with a redesigned shutter while keeping the same excellent 24.3MP full-frame sensor and weather-sealed body.
Image quality identical to D600 — excellent dynamic range, strong colour, clean high-ISO to about 6400. 39-point AF with 9 cross-type centres — competent but clustered in frame centre. 6fps burst (up from 5.5). 1080p 30fps max video.
Nikon F mount, dual SD card slots, weather-sealed magnesium body. Built-in flash — unusual for full-frame DSLR. ~900 shots battery life. Fixed 3.2-inch LCD, no touch. Wi-Fi via optional adapter only.
Common used at attractive prices. Verify the shutter is D610-spec — check serial against Nikon service records. Inspect sensor for oil spots. The D750 is worth the premium for improved AF, tilt screen, and Wi-Fi.
