Zeiss Ikon Nettar 515/2

Zeiss Ikon's Nettar series was a successful line of self-erecting folding cameras for 120 roll film (often described as B2 6x9 film).

Zeiss Ikon always advertised the Nettar series as something for the amateur photographer. Nevertheless, these cameras share many parts with the much more expensive Ikonta series (for example body and struts). The Nettar series may lack the above-specified lens / shutter combinations and things like film type and speed memo discs, but the perceived build quality is on par with the Ikontas.
