Nikon Z-mount (stylised as ) is an interchangeable lens mount developed by Nikon for its mirrorless digital cameras.

The EF mount reverses this logic, providing the bayonet on each lens, and a receptacle on the camera body. When the EF mount was introduced in 1987, it had the largest mount diameter (54 mm internal) among all 35 mm SLR cameras. [2] The EF series includes over eighty lenses, encompassing focal lengths from 8 to 1200 mm.
With any other lenses the camera's electronic rangefinder (which indicates if the subject inside the selected focus point is in focus or not) can be used to manually adjust focus. [11] [12] The D5300 can mount unmodified A-lenses (also called Non-AI, Pre-AI or F-type) with support of the electronic rangefinder and without metering.
Canon full-frame cameras have used the EF lens mount since 1987. In comparison with that mount, the RF mount's inner diameter is the same at 54 mm. [1] The RF mount's flange focal distance at 20 mm is much shorter than that of the Canon EF and EF-S mounts at 44 mm. The EF-M mount has a flange focal distance of 18 mm.
