I picked up this 1953 Zeiss Ikon Super Ikonta III 531/16 in Feb 2015.
Its condition was surprisingly good bar a fogged rangefinder, dirty lens and some minor corrosion on the top plate.
The bellows are light tight and the coated Novar Anastigmat 75mm f3.5 lens shows only light polish marks. The Synchro Compur shutter seems pretty accurate beyond 1/2s and a little slow at 1s. Focus and aperture controls are smooth and the rangefinder is spot on.
I spent about an hour disassembling the top plate, cleaning the lens and rangefinder, lubricating all pivots and polishing the leather trim. The result, a very clean and useable folder.
The Super Ikonta III 531/16 was one of the last 6×6 folders made by Zeiss Ikon before 35mm took its hold. It weighs 662g and folds to a very compact 135x100x45mm – hence some refer to it as the “Pocket Hasselblad”.
Here’s a 2400 dpi scan of T-Max 400 shot at f/11…not too shabby for a 3 element 60 year old folder!
