Which I much agree with, I woud like to point out to those who might
consider exploring MACRO stereo that the deWIjs attachments can provide the
same ease when doing MACRO stereo.
They are made to adapt to YOUR CURRENT SLR ( you tell us what camera you
use and we make it for that bayonet) , are very easy to use, and yield very
sharp half frame images.
The deWIjs MACRO stereo is NOT a beam splitter, as many seem to perceive it
to be when they see it at shows. It is actually a pair of tiny lenses
set in to an anodized aluminum barrel, with a focus field extension arm,
and field of focus posts.
There are four attachments sizes available;
Field size 18 x 24mm/ 10mm lens base
Field size 36 x 48mm/ 12mm lens base
Field size 46 x 72mm/ 14mm lens base
Field size 72 x 96mm/ 15mm lens base
Peter Davis pointed out one of the weaknesses in beam splitters as:

Well for some subjects...I find the half frame format more appropriate than
full frame MACRO. Composing for MACRO is a whole different world that the
larger world beyond (as I am learning in lots of small ways!).....so
sometimes the tight tolerances of the vertical half frame format are just
what is needed.
