Camera without filter wheel

If the camera model, intended for usage with External filter wheel, is used
without filter wheel at all, two types of adjustable adapter bases can be
used.
When a "thin" adapter base, intended for camera with Internal filter
wheel, is used, the back focal distance is only 21 mm.
