Quoting Paul Ewins <[email protected]>:
Hi Brian,
I own an MF and two MF-1s but don't know much more than you. I do
believe that it is meant for some sort of endoscope/gastroscope set
up which would bayonet on to the end of the lens/adapter. Only one
of mine has the endoscope adapter and it is different to yours -
shorter and with the designation AP-K55 so I guess there were
different focal length adapters to vary the magnification.
A couple of other things - you say it has no focussing screen, but
does it have the semi-spherical protrusion below the prism? If I
mount a lens on mine I still get a focussed image. The other thing
is that although based on the ME it has the two pins on the back for
the old-style databack which would make it the only ME style body to
do so.
Yes - it does have the semi-spherical protrusion and I can focus with
a normal lens attached. What I meant was that it doesn't have a
standard ground glass screen.
I'd love to find some sort of instruction manual for it - I assume
they must have existed.
Now you mention it, I hadn't noticed the pins for the databack.

Cheers

G'day all
I knew these things existed - there's a photo of a similar one on
Boz's site - but I'd never seen one "in the flesh" until the last
camera market in Sydney.
So I just had to have it :-)

It's of absolutely no practical use but it's interesting, just the
same. It's based on the ME but has no focusing screen and a has
spot meter built into the top of the pentaprism. The apparently
missing right had strap connector isn't. That's the way it came
from the factory.
This one is the original half-frame version - the one on Boz's site
is the later full frame version (MF-1). There was also a similar
one based on the MX (see Dario's Asahi Optical Historical Club).
A couple of questions..
Was this the only half frame camera Pentax produced?
Does anyone know exactly how it was used? All that crops up in
internet searches is that it was used "for medical purposes" - some
say optometry; some say endoscopy.
