Think about the early Pentax lenses, before there was any diaphragm
operation. The mount was smaller than the 42mm screw mount -
something on the order of the 39mm LTM, maybe a scosh smaller. Then
came the lenses w/auto diaphragm and the mount became larger.

Because I was playing around with adapting a Pentax hood to a Leica
lens, and just started wondering about how close to a Leica in design
and operation a Pentax could be made. The M2 and M3 have no Leica
nomenclature on them that's observable when looking at the camera head
on, and seeing the M3 with a Pentax logo on the lens hood just moved
my thinking along those lines.
Think about it for a moment: The Pentax MX is substantially smaller
than a Leica, so, by stripping out as much stuff as possible my
thought was to make a very quiet SLR and, perhaps, have smaller lenses
as well. Part of the idea came from the fact that Pentax makes the
43mm LTD in LTM, which, as noted earlier, probably has no diaphragm
coupling, and no AF stuff within the barrel. I suspect that this is a
very small lens. As I write this it occurs to me that it would be very
cool to be able to adapt some Leica lenses to an MX or MX-like body.
While the wide angle lenses might not be able to be adapted, I suspect
the lenses 50mm and above could be.
Anyway, the real reason i ask this is because I'm a person with great
curiosity.

No, I like the Leica just fine, although it's taken me a while to get
used to its operation. The focusing and viewfinder came easily to me.
However, when I put the 90mm Elmarit on the M3 I had a problem since I
was expecting the image to be magnified, so it took me a couple of
rolls of film to adjust. I like being able to see outside the frame
lines, and a TTL finder would ruin that.
