Subject: [rollei_list] Ikonta Film Spacing was Fuji/Bessa
folder rangefinder.
Bill,
The negative overlap is the achilles heal of the more
advanced Super Ikontas with todays films. Here is what
Henry Scherer wrote to me after he had done a full overhaul
of my Synchro Compur BX (1 1/2 year wait!):
"...There is one thing about your camera that needs to be
changed to accomodate modern times. When the automatic film
advance mechanism was designed, film was a lot thicker than
today. This means, if the film is loaded in accordance with
the original directions the frame spacing will be off and
you will loose at least one frame. Years ago I experimented
with some old modern type film and developed a loading
method that provides slightly uneven film spacing, but 12
frames per roll. I've attached a picture of how the film
should be lined up in the camera in order for the automatic
film advance system to be synchronized with the modern roll
of film. Just load the film and advance it until the arrows
are precisely aligned as shown in the attached picture, then
close and lock the camera door. Next, flip the automatic
film release button to the left so that the red dot changes
to silver, and then rotate the film advance knob until it
stops at frame "
There is more on this problem (and suggested
"compensations") on his site:

I actually never got the film spacing issue under control
and it bothered me so much, since I wanted to shoot chromes
at least occasionally, that I sold the camera.
I hope my "new" much simpler 521/16 will not have this
problem.
Jan
It seems to me that the Super Ikonta B shoots 11
pictures per roll but the BX, the one with the meter on top,
shoots 12 pictures. What was different between these models?
