Zeiss Ikon Ikoflex Ia 854/16 – 1954


I got this as novelty present for my lads’s 25th birthday.

The camera was listed with a shutter fault and both lenses were milky with fungus.

Upon arrival I removed and cleaned both lenses and set about repairing the Prontor-SV shutter.

Initially I thought it was just dust and lack of lubrication, but once clean, I found that the shutter release mechanism was forced and a number of internal components bent (highlighted in red).

I disassembled the escapement, timer release and shutter linkages in order to work out how to repair it.

After a few hours of pondering and scouring the net to find some diagrams, I found one picture of the internals of a working shutter. I then set about re-aligning the parts.

The tolerances in these things are quite strict with all speeds being regulated by a combined slow/fast speed escapement.

Happy to say after another few hours of assembly/disassembly, I finally got the shutter to work at all speeds along with the self timer.

The Zeiss Ikoflex Ia is a robust, compact and extremely well built TLR made between 1952 and 1956.

This one has the Novar Anastigmat 75mm f/3.5 taking lens coupled with a Teronar Anastigmat 75mm f/3.5 viewing lens.

The shutter release is on the top plate and can only be fired when wound on, cocked and with the WLF open.

The exterior polished up nicely and IMO the worn paint around the lenses revealing brass adds to the appeal.

Hopefully this camera will see out another 60 odd years!
