Hi! Wouldn't using stochastic sampling ("AM3") with zero value for aa but a tiny
camera depth of field "aperture" so that you can keep its sample count minimal
between 3 and 5, the whole thing focused at the distance of your cylinder's
surface do the trick for you ? (I often ended uo using no aa and using only
aperture instead in the cases where I wanted some really photographic look
anyway. and it ended being a better trade off.

Otherwise, Le Forgeron's branch (HGPOVRAY38) has many additional camera types,
(among which a stereo one) does none suit your use?
