But 1:2.9 on a 6x6 doesn't let you take pictures of anything smaller
than 162x162mm; hardly macro. Most 'macro' zooms for 35mm let you
take frame filling pictures of smaller things, and SLR's get closer
with a lot less fuss and more accuracy. I used to have a Rollei with
a 3.5 Planar in the sixties for a while; a lovely camera and great
for a number of things, but not for closeups. Also, your parallax
error increases as the subject gets closer to the camera.
BTW, I forgot about the sliding mask opening up at the bottom. You're
quite right there.
It should really be called framing compensation, because it does
nothing about parallax as such. However, everyone calls this sort of
thing 'parallax compensation', just as zooms that can focus to 1:4
are called 'macro zooms'. Marketing takes over.
