Hi Chuck,
I understand what you are saying about the reflection from the rear
element, but find that hard to understand when the lens is 8 inches away
at the end of a bellows. I'll keep pondering it.
Your old LTM lenses are interesting. I had a 50/1.5 at one time. It
was very soft wide open. My sample was in poor shape mechanically, and
I sold it. The 90/4 and 135/4 are still respected lenses. I just
bought a 90/2.8, but in Leica-R mount, and really like it.

It's the lack of coating to suppress the reflections. But it even
happens with some more modern lenses that do have coatings. I've not
seen it with any of my Zuikos adapted to either the Canon 5D or OM-D
cameras but I haven't used many of them that way. I've used the 50mm
lenses (both 1.8 and 1.4) as fast portrait lenses to restrict depth of
field and taken a few snapshots with other lenses but not paid much
attention to the results. I have also used the Minolta 58/1.2 briefly
(unfortunately, somehow misplaced since the last move). I have a
some old Leica screw mount lenses from the 50's that I've been meaning
to try but keep forgetting about (50/1.5, 90/4 and 135/4).

I didn't know what to attribute that to. Thanks!

Pretty good for that old timer. It's a little soft but not bad
considering the age. I noticed the reflection between rear element
and sensor in the red roof shot.

Exchanges with Moose, on the OM list, about older lenses, and his
recent
studies in colors, led me to try a couple of experiments this morning.
I mounted my Ross London No. 6 Symetrical 8-inch f/16 lens, from about
1890, on an E-510, and put the combination on a tripod.
Aiming the camera at the Buddlei bush from quite a distance, I saw
butterfly activity. Snapping several exposures, I got a lucky hit.

I also tried an out-of-focus view of a neighbor's red roof and some
foliage.
