The Zeiss Ikon Ikonta 520/2, also known as the Ikonta C, is a folding medium-format film camera that takes 6x9 cm exposures on 120 roll film. Introduced in the 1930s, it sat in Zeiss Ikon's range of self-erecting bellows folders aimed at photographers who wanted a pocketable camera capable of delivering large negatives.

Sales data for the Ikonta 520/2 is thin, with only a single UK auction-hammer result of £31 on file, so any view of what one is worth today should be treated as indicative rather than settled. At saleroom level, working folders of this generation typically change hands at modest prices, and value is highly sensitive to bellows condition, shutter accuracy and lens clarity. A specific recent example sells for around £30 at hammer, but cleaner bodies with the higher-grade Tessar lens variants tend to command a premium over basic Novar-fitted ones.
