Dear John,
there are small screws to adjust the plate against which the screen is pressed.
I saw it once at the assembly line in factory for the 3003.
They can be accessed from top with tiny screwdrivers and it looked to me you
need a good skill to do so.

Hi Dirk,
The biggest problem I had was trying to focus a QBM on my Canon 400D - the
screen on the 400D is not designed for manual focus and it is difficult to
judge the perfect point - but my eyes are not as good as they used to be ;-))
No idea about other camera's screens though.
The 80mm f1.4 and 35mm f1.4 will fit on the adapter but you cannot easily
remove the adapter because it is smaller than the lens barrel. Being only 1mm
thick, you have nothing to grip!
Infinity focus seemed OK - QBM lenses focus have about 1mm extra focus and the
adapter is thin enough to bring the lens forward to enable infinity focus. The
Canon is the only SLR camera that has a large enough throat and short enough
focus length to accommodate most other manufacturer's lenses.
Exposure is just a matter of trial and error. Possibly due to the angle of
light rays on a film lens compared to the modified light path on a digital
lens, the meter gets variable light intensity.
I had a similar problem with my 3003; the factory said it was OK but when I
sent it to the Rollei expert in UK, he adjusted it slightly. It may be
something you can do yourself providing the lens focuses at the plane, it just
requires a slight movement of the screen. You could try removing and replacing
the screen or trying a different screen. It may not be properly seated... I do
not have a manual to see how you do this though.
Regards
John

Dear John,
thanks for the link to the very comprehensive article.
I think the overexposure issue should be a problem to be solved, so It just
needs more manual adjustments.
I had the same problem with a M42 Zeiss Flektogon lens on an Olympus E1 (Four
Thirds). Without the chip the exposure is ok, with chip the exposure was
heavily overexposured.
My interpretation is that the chip tells in a - wrong - way, the aperture is
set to say f 8, but currently the lens is fully open for focussing. Then the AE
thinks it has to increase the exposure time.
Did you have problems to focus to infinity with the Rollei to Canon adapter?
Also the other issue at the Sl2000 with screen adjustment, that microprisms
cannot get fully clear at infinity of the lens, is known to me. My SL2000 has
the same.
Has been -in earlier times - a lot of times directly at Rollei and came back
without change.
Once I went with it directly to the production line where the SL3003 where
mounted. The technician said, the adjustment was in specs of tolerances and
hence needs no further adjustment. I could not convince him to adjust "more to
zero tolerance".

Dirk

Hi Dirk,
I wrote about using an adapter in Issue 16 of Club Rollei User:
http://rollei.org.uk/2010/01/club-rollei-user-issue-16/
There is a problem with using a chip - it needs to be situated where the
stop-down pin is on the QBM lenses. Hence a manufactured one does not seem to
be on the market. I have thought about Aralditeing a chip at the bottom of the
mount but have not got around to it yet. You have to stop down the lens
manually anyway so this would not necessarily be a problem...
Regards
John

Thanks for this information, Pierre.
Can you tell which adapter you haveß
I heard that most adapters do not work with the 1,8 50 Planar as the back of
the lens goes too far into the adapter.

Hello,
There are 2 kinds of adapter: with or without the AF chip. Without, you're on
your own for the focusing. With, you get the little red box to confirm where
you're in focus.
The chip is available on its own if needed. I have one without and it works
quite well, I have tried it with the 55/1.4, 50/1.8, 85/2.8 and some non-Rollei
28-70 macro lens (don't remember the brand). They all worked fine on my 5d and
1d. No exposure problem. When I tried it on the 450d of a friend of mine, it
seems it didn't like the all-metal adapter and started to blink ...
I have been told as well that some lenses may hit the mirror but it seems I
have none of them.
So your mileage may vary.

Hello,
has somebody experience to use our loved SL35 Rollei lenses with QBM at Digital
Cameras?
I just bought an adapter to use on Olympus FourThirds, but I did not yet
receive it to test it.
Adaption should also work to Canon, but some adapters allow no infinity
focusing while I also read that some lenses got so deep back at infinity that
the mirror of the Canon would touch the back of the lens.
Any reports of own experience and also recommendations for adapters and best
camera bodies combinations to be used are appreciated.
Yes I know, finally this is then no more a Rolleiflex.
But maybe using a Carl Zeiss Rollei 1.4/85 at a Canon will finally let us
continue to use some good Rollei staff!
;-)

Dirk
