There was a lens design developed by an Australian optical engineer for
documentary work that had an unbelievable depth of field. I remember a shot
with David Attenborough (who else) and a caterpillar, both in focus and
both apparently the same size - the caterpillar within inches of the lens
and the attenborough several meters away. I believe said developer rents
out the lenses for Discovery Channel type purposes and that they are worth
a fortune, each one hand built to purpose.
More than this I know not.

This has a vaguely familiar ring to it. I remember seeing something
about a lens attachment years ago where a close up lens was ground
into part of the front, sort of like a blended lens bifocal. It
allowed an extreme close up in part of the frame with the background
at a different focal length. It seemed like a stupid idea and the
demonstration photo did not raise that low opinion of it.

Yes - I have one. A cheap 'Focal' filter with a half macro diopter and half
nothing, so you have to be careful to lose the horizon line in the
shrubbery. Cokin also make a similar one and B+W have a couple under the
name Bifo - although theirs is an insert of about a one quarter macro field
in a full filter and is pricey, as you would expect from much higher
quality. Haven't got around to using it yet :-) The movie lens I
mentioned however, is a genuine massive DOF lens at a reasonable aperture.

I have to admit I am skeptical of a device that purportedly gets
around the physics of normal optics.
