I have often wanted to experiment with high magnification photography with reversed movie lenses. They are mentioned in passing in many books including Shaw and in slightly more detail in Lefkowitz (pp. 133) but apart from names like cine raptar and switar I know next to nothing about them. So any source of information about movie lenses would be appreciated - especially in the context of macro photography with 35mm equipment.

What are the 'normal' lenses for the various movie formats - 8mm, 16mm etc. Does anyone have any experience using them for macro photography. Do you use bellows or extension tubes. Any input would be welcome as it would add to my non existent knowledge on the subject.
