1. Ratio 1:2, with 27mm extension tube 1:1.
2. Better correction for infinity than the f/4.0 version.
3. Ratio 1:2, with 27+20mm extension tube 1:1. Hard-to-find, very good
quality lens.
4. This is the ``Medical'' macro (now called ``Dental Eye''). In
current versions, it has been permanently integrated with the body
but older versions had a standard Y/C coupling. It has a built-in
ringflash (GN 5.6m) and a composing lamp. Maximal focusing distance
1.5m. Flash and aperture are coupled to the repro ratio which is
1:1 with 2:1 with an extra add-on lens. A number of options are
available, like a foot switch, a mains adapter and a reflector set.
5. ``Bellows''. Can only used with bellows, ratio 1.4:1.
