Dear Carlos,
You always have such interesting reports - I love reading them. You are also
lucky to have more than one Rollei camera - and a nice "problem" to have, to
adjust to the differences! :)
I hope 2016 is very good to you and everyone on this list. Happy and safe and
peaceful holidays to all!
Nancy Kennedy

Subject: [rollei_list] As a matter of Rollei TLR curiosity
Perhaps it could be better to say a matter of Compur shutter curiosity. I'm
using Rollei TLTR cameras from about 43 years ago; the Rolleiflex 2,8C Xenotar
was my most used TLR because it was my father's TLR and, despite I have used
other TLR cameras along this time BTW; however I have used very much the F
cameras beside the 2,8C and 'cord IV during the last 8 years, first the 3,5F
Planar and now the 2,8F Planar.
I got an initial annoying sensation each time I tried to set the shutter speed
for the F cameras after to use the 2,8C because I always rotated the shutter
speed wheel to the wrong direction, it was a very minor issue and I never
thought about it. But today I put the 2,8C and the 2,8F side to side to compare
the F linear shutter speeds scale against the C non linear shutter speeds scale
and I noticed that you need to rotate the wheel in counterclockwise direction
to set faster shutter speeds for the F cameras and in clockwise direction to
set faster shutter speeds for the 2,8C (and vice-versa for slower shutter
speeds). It's the explanation for my annoying sensation each time I use one of
the two models; the cameras have different wheel rotation direction to adjust
shutter speeds.
The Rollei Rport IV describes the way Rollei needed to do some slight internal
changes to adapt the Japanese Seiko and Copal shutters to the 2,8GX because the
shutter speeds direction was opposite regarding the Compur shutter with linear
speeds scale, but it's evident it happened in the past too with the Compur
shutter different versions. In the other hand, there is no difference regarding
the direction to set the f stops between the C and the F.
Carlos
