[KOML] Parallax and Rollei

["Kotsinadelis, Peter (Peter)" <peterk@lucent.com>]

Hi Mel,

Thanks for the compliments.  I thought I did mention it?  Anyway, all the
Rolleis have had Parallax compensation since their debut. That was one of
the greatest features of theit TLR.
It was a patent that drove their competitors crazy.  There is a slide
underneath the viewing lens that moves a frame.  You will see this
represented as a shadow in the viewing screen as you change focus from
infinity to close (watch the top of the viewing screen and you will see the
shadow get larger). 
 
Voigtlander was the former employer of Heidecke who designed the Rollei.
They were sued by Rollei (F&H) when the tried to offer a similar camera and
hence they had to redeveloped their TLR where one of the features was that
the viewing lens actually tilts slightly when you close focus.

TLRs like the Mamiya C series, YashicaMats, Minoltas, etc. did not have
built-in parallax compensation.  In some cases, like with Mamiya it was an
add on which I think they called a paramender.

Right on, Eric. I use a 180 on my C-33 for portraits, and am looking for a
140 for the RB67. I just like the extra versatility I get with the long-rack
bodies. With my C-33 or RB67, I can do product shots, photocopies, and the
obligatory wedding-bands-on-hands shots without having to fiddle with
accessories.

Good to know. I looked for that bit of information in Peter's August
Shutterbug article, but didn't see it. (Good work, Peter! Very informative
series.)
