The Zeiss Ikon Nettar 510 is a medium-format folding rollfilm camera produced by Zeiss Ikon as part of its budget-friendly Nettar range. It sits below the company's Ikonta line and was aimed at amateur photographers seeking a compact folding camera at a modest price when new.

Sales data for the Nettar 510 is very limited, with one recorded UK auction hammer result of £18 in October 2024 — a wholesale saleroom level rather than a retail asking price. On the basis of that single data point, the Nettar 510 currently sells for a low double-digit figure in today's market, though condition, working shutter and bellows integrity will materially affect what any individual example is worth.
