Nikon D810 flatbed 8 constant aperture and excellent

8 constant aperture and excellent compatibility: this D-type lens will mount and shoot on any Nikon F-mount SLR

a 39-point autofocus system

Basic and easy to use- and it runs off a pair of common AA batteries (included)

built-in AF-S motor for fast and quiet autofocus

so I suppose it counts

Nikon D810 flatbed 8 constant aperture and excellentThe Nikon D810 is a professional full frame DSLR with a 36mp sensor, full HD video capability, and a fast 51 point autofocus system. Compatible with Nikon F mount lenses from the AI series on up, the D810 is as nice a platform for classic Nikon lenses as it is for new ones. This D810 is in excellent condition, with only very minor cosmetic wear and approximately 64k actuations not super low, but the shutter is rated to 200k, so there's plenty of life
