SUMMARY
While not as groundbreaking as the Nikon D800 or as acclaimed as the D850, the Nikon D810 is a solid DSLR that deserves recognition. It addressed the D800's autofocus bug and introduced several upgrades, including a new sensor without an anti-aliasing filter, an improved EXPEED 4 processor, and a lower base ISO of 64. The D810 also offered faster burst speeds, Group-Area AF, and better video capabilities with full HD at 60p. Despite being a decade old, it remains a reliable and slightly better-specced option than the D800, especially on the used market.
