C-mount lenses provide a male thread, which mates with a female thread on the camera. The thread is nominally 1 inch (25.4 mm) in diameter, with 32 threads per inch (0.794 mm pitch), designated as "1-32 UN 2A" in the ANSI B1.1 standard for unified screw threads. The flange focal distance is 17.526 millimetres (0.6900 in) for a C mount.
Example (inch, fine): For 7 ⁄ 16-20 (same diameter as the previous example, but this time with 20 threads per inch, which is considered fine), 0.437 in × 0.90 = 0.393 in (i.e., if the threads are to be fine, then a slightly larger diameter drill bit should be used before tapping the hole for the screw).
The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch.For diameters smaller than 1 / 4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.
The switch has two settings on most lenses: Mode 1 and Mode 2. The newest IS Mark II versions of certain EF super telephoto lenses (the 300mm f/2.8L, [6] 400mm f/2.8L, [7] 500mm f/4L, [8] and 600mm f/4L [9]), plus the 200–400mm f/4L IS [10] and 100–400mm f/4–5.6L IS II, [11] have a third setting, Mode 3. Mode 1 is normal mode, used for ...
