The D850 is the first Nikon DSLR featuring a back-illuminated image sensor claiming overall a one-stop image quality (image noise) improvement. [5] This camera was the first full frame DSLR achieving 100 points at Dxomark. [6] The D850 also won Camera of the Year for 2017 at Imaging Resource. [7] Rear of the camera with articulating screen
Diagram illustrating the flange focal length of an SLR–type and a mirrorless–type camera. For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus [1] or register, depending on the usage and source) of a lens mount system is the distance from the ...
A method variously referred to as trap focus, focus trap, or catch-in-focus uses autofocus to take a shot when a subject moves into the focal plane (at the relevant focal point); this can be used to get a focused shot of a rapidly moving object, particularly in sports or wildlife photography, or alternatively to set a "trap" so that a shot can ...
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror.. The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power.

The Nikon D70 is a digital single-lens reflex camera, introduced at the 2004 PMA Annual Convention and Trade Show, as Nikon's first consumer-level digital SLR, and a competitor to the Canon EOS 300D. [2]
For a camera focused on this distance, D 1 = ∞ and D 2 = h/2, and we see that the range of distances acceptably in focus will run from just half the hyperfocal distance to infinity. The hyperfocal distance is, therefore, the most desirable distance on which to pre-set the focus of a fixed-focus camera.
