Other devices, such as split-image prisms or microprisms, can help determine focus. Manual focus lenses can also be used on modern digital cameras with an adapter. Zeiss , Leica and Cosina Voigtländer are among current manufacturers who continue to make manual lenses in lens mounts native to modern cameras.
Object recognition – technology in the field of computer vision for finding and identifying objects in an image or video sequence. Humans recognize a multitude of objects in images with little effort, despite the fact that the image of the objects may vary somewhat in different view points, in many different sizes and scales or even when they are translated or rotated.
Cellphones, digital single-lens reflex and compact digicams, laptops and personal media players offer video-capture capability, but most multipurpose devices offer less video-capture functionality than an equivalent camcorder. Most lack manual adjustments, audio input, autofocus and zoom. Few capture in standard TV-video formats (480p60, 720p60 ...

Modern still camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body. Screw-threaded mounts are fragile and do not align the lens in a reliable rotational position, yet types such as the C-mount interface are still widely in use for other applications ...
