A thread for image circles beyond C-mount

The M42 thread is used where the sensor is too large for C-mount: large area sensors and line sensors of a few thousand pixels. The thread diameter is fixed at 42 mm, but the pitch and the flange distance are not the same on every camera, so the mount name alone does not establish that a lens and a camera fit together.

  • Compare the image circle printed for the lens with the sensor diagonal or the line length, pixel count multiplied by pixel size.
  • Check the thread pitch and the flange distance of the camera against the lens; an adapter or spacer tube is often part of the layout.
  • Read the recommended magnification range. Lenses of this size are corrected for a range of magnifications and lose resolution outside it.
