The Novoflex Automatic Bellows is a combination bellows unit and macro focusing rail, and allows for open-aperture metering by employing connections which will close the diaphragm only at the moment of exposure.
Using bellows is the classic and proven path to macro and micro photography.
Note! Due to the protruding prism design of the EOS 1D series the EOS 5D, the bellows can not attach directly to these cameras. As a solution, an "extension tube" can be used to provide more spacing, but that will also change the focal length.

Comments about Novoflex Auto Bellows for Canon EOS:
I used this bellows to space a 100mm Canon macro lens about four inches from the Canon 5D to take some pictures of some very small mechanical parts about the size of a grain of sugar. It worked as advertised, sending the exposure and focus information to the camera because of the lens contact wiring. Independent adjustments for lens spacing (magnification) and the rail distance adjustment (focus) made setup a breeze.
