[OM] 38mm macro and focus screens

Thanks, Piers.
An animated illustration is worth 10,000 words.

Mike, have you seen Harold Merklinger's articles of the Scheimpflug 
rule for
tilts? Readable, despite the mathematics, with a rather neat set of
animations. All is linked from this page:
http://www.trenholm.org/hmmerk/index.html

The answer to your magnification-v-DoF conundrum might be hinted at in 
the
QT animation: http://www.trenholm.org/hmmerk/HMbook18b.html

Merklinger also has interesting "different" things to say about other
topics, depth of field for one.

Piers
