James,
Judging by the serial number your lens should be a QBM IV - my sequence of
numbers is:
ROLLEIFLEX SL35 ROLLEI 50MM F1.8 PLANAR GERMAN 1034892SL
ROLLEIFLEX SL350 ROLLEI 50MM F1.8 PLANAR 5509368
ROLLEIFLEX SL35M ROLLEI 50MM F1.8 PLANAR 1222027 -
this is a lens purchased later so without checking is probably a QBM IV
ROLLEIFLEX SL35ME ROLLEI 50MM f1.8 PLANAR 1032003
with the following being QBM IV lenses
ROLLEIFLEX SL35E ROLLEI 50MM f1.8 PLANAR 1207367
ROLLEIFLEX SL35E ROLLEI 50MM F1.8 PLANAR 1285673
ROLLEIFLEX 3003 ROLLEI 50mm f1.4 PLANAR 3120650
If there is a recess and a lip, I think it is QBM IV. From memory (my lenses
are not in front of me) on the earlier lenses it is not so much as a sunken
ring as a 'cap' which has no recess.
It measures about 0.5mm so it isn't very noticeable.
If your extension tube gives an aperture reading, something is out of
adjustment.
This tub has a slightly less than 2mm recess so it should read. This is
the tube that is normally only sold with the 60mm f/2.8, not the
standard extension tubes.
Because there is no aperture connection between lens and camera
body, there can be no aperture information displayed in the viewfinder. This
would then explain why your lens does not show up in the viewfinder unless
it is actually a QBM III
What happens with your 60mm Makro?
I only have the tube which I bough for a Dollar.
Does the aperture reading show and then change if you gently press the pin
on the camera?
Yes, you have to also wedge a small piece of cardboard in the aperture
coupling slot, but then it will read the full range of maximum opening
from 8 to 1.4 and then they all come on as the pin is pressed.
The only other thing is the black 'stop-down' button below and on the right
of the lens - opposite the red lens release button, could be in stop-down
mode. To check, remove the lens and press the button. If in stop-down, the
'flap' at the bottom of the lens opening will be out; in automatic mode the
flap will be retracted. But I expect you know that anyway.
Yes, I tried clicking that a few times, didn't help.--
