Cameras/Zeiss Ikon Camera Price Guide


I have a Zeiss Ikon Bob 510/2, Nettar 10.5cm, f/7.7.  Serial Number D37483.

I believe it was made in Germany around the 1930s. I would rate the camera as being of average condition.  There is also a leather case which appears to be in good condition.

I would welcome your opinion on a current price valuation.

Thanks you very much.


The Bob 510/2 (also marketed as the Nettar 510/2) is a simple amateur's self-casing folding bellows camera, made by Zeiss Ikon of Germany from 1936 to 1941, for 2 1/4 x 3 1/4 inch exposures on #120 roll film. It's a very common model, especially throughout Europe, and truly excellent examples only tend to sell for about US$50 in today's collectible camera market. The supply greatly exceeds the demand, so condition is the key...less than excellent is difficult to sell at any price.

Best wishes,

I'm an expert on all types of antique, classic, and contemporary cameras, as well as the general history of photography. Everything from ancient box cameras to modern single-lens-reflex; from simple Kodaks to sophisticated Leica and Nikon; from glass plates and roll film to movie and 35mm. I can identify and appraise them, explain how they work, and offer insights on their restoration and care. I can also provide historical background on vintage cameras and equipment, and guidelines on their purchase and sale.


I've been a professional photographer and a student of the history of photography for nearly 30 years. During that time my collection of vintage cameras and photographic paraphernalia has grown beyond 2000 significant pieces. I've published nearly 70 articles in the field, including 16 in the popular "Buying Classic Cameras" series for PHOTO SHOPPER MAGAZINE from 1995 to 1997, I'm currently a contributing editor for CAMERA SHOPPER MAGAZINE and McKEOWN'S PRICE GUIDE TO ANTIQUE AND CLASSIC CAMERAS, and I've written numerous entries for WORLD BOOK ENCYCLOPEDIA. Portions of my collection have been displayed in museums and special exhibits in the past two decades, and many of the items were photographed as illustrations for books. In 1985 I founded the International Photographic Historical Organization (InPHO), which eventually evolved into its intended purpose as the best first resource for information on the history of photography. I'm also a founding member of several e-mail forums dedicated to specialized areas of photography, and I'm the moderator of the Internet Directory of Camera Collectors (IDCC), which remains the largest and most successful such group in the world.
