Nikon's 36MP full-frame DSLR, a resolution benchmark that defined landscape photography.
The Nikon D810 was released in June 2014 as the successor to the D800 and D800E, combining the high-resolution 36.3MP FX sensor without an optical low-pass filter — providing the resolving capability of the D800E without a separate product line — with the professional 51-point AF system and expanded ISO range. At 36.3MP it was the highest-resolution Nikon FX DSLR available until the D850 in 2017. No 4K video is included; the D810 records up to 1080p.
The 36.3MP FX CMOS sensor without OLPF pairs with dual EXPEED 4 processors. The 51-point Multi-CAM 3500FX II AF system provides 15 cross-type points for subject tracking. Burst shooting runs at 5fps in FX mode and 7fps in 1.2x crop mode. 1080p video records at up to 60fps via HDMI (internal records at up to 30fps). ISO 64-12800 native. Dust and weather sealing is built throughout. Battery life approximately 1,200 shots using the EN-EL15a, body weight approximately 880g with battery and card, dual card slots: one CompactFlash Type I/II slot and one SD/SDHC/SDXC slot simultaneously for backup or overflow.
The 36.3MP without OLPF resolves more fine detail than OLPF-equipped sensors at equivalent megapixels — visible in high-frequency textures like fabric, brick, and foliage at the pixel level. The base ISO 64 (lower than the standard ISO 200 of most DSLRs of the era) provides the widest dynamic range of any Nikon DSLR at launch, particularly useful for landscape and studio photography. The D810 was the reference landscape and architecture DSLR for the Nikon system until the D850.
On the used market the D810 is very affordable for a 36.3MP professional FX body. Condition checks: shutter count via EXIF — rated 200,000 actuations — EN-EL15a battery health, CF and SD slot contacts, and weather sealing at port covers. The EN-EL15a is backward-compatible with the EN-EL15 and forward-compatible with EN-EL15b/c from Z-series bodies. The D850 (2017) provides 45.7MP, 4K video, and BSI sensor at a premium. Compatible with all Nikon F-mount lenses.
