Manufactured probably in the 1960s or 1970s by Nikon in Japan, this is their C35 35mm microscope camera.  Because the camera was intended to be used with a microscope, and because there is no viewfinder or shutter built into it (all it does is advance the film), it is often referred to simply as a "dark box."

This dark box is unique because it's a dual format camera.  By simply turning the chrome knob on the top of the camera you can switch between full-frame and half-frame mode (allowing twice as many exposures on a roll of film) and the film advance lever automatically switches too so that your film will advance the correct distance depending on your chosen format.

Pulling up the tab (which is actually a dark slide) seen above the lens-mount on top of the camera raises the dark slide to let light reach the film.

The frame counter's numbers are upside down compared to normal 35mm film cameras.  This was intentional so that users could read the numbers properly when the camera was mounted on top of a downward-facing microscope.  The camera has standard 39mm mounting threads and comes with a 39mm adapter that screws into the mounting threads and provides a 55mm non-threaded mount for attaching to the microscope.

I bought this camera many years ago for a custom camera project which never got built so it's time to pass it on to someone else who likes to experiment and might come up with a creative way to utilizes its unique dual format options.

The camera is working properly and is in excellent condition showing little evidence it was ever used.  Please use the photos to judge the camera's condition.

SHIPPING:Domestic shipping is via USPS Priority Mail and will be calculated by eBay's shipping calculator to your particular city.

The shipping fee also includes postal insurance plus the additional fees imposed by EBay and PayPal on the shipping charges, which amounts to an additional 15% on top of the fees charged by the post office. Shipping discounts are available for multiple purchases shipped to the same address in the same box.

International buyers please note: The shipping charges you pay when purchasing this item do not include import duties, taxes, broker's fees, or other charges that may be imposed by government officials or Customs brokers in your country. Please check your country's import regulations if you want to be informed about any additional charges that may be imposed on your package when it arrives.

PAYPAL PAYMENT REQUIREMENTS: Visa and MasterCard are accepted through PayPal for domestic purchases. For international purchases, because of PayPal and eBay's very strict rules regarding proof-of-shipment for sellers, if you want to pay for the item using PayPal, and the item sells for less than $750.00, I can only accept a PayPal payment if you are willing to pay for USPS Priority Mail Express International or Priority Mail International shipping. They are the only on-line-trackable shipping methods offered by our US Postal System to international destinations, and an on-line-trackable shipping method is a PayPal and eBay requirement. If the item sells for more than $750.00, then Priority Mail Express International is the ONLY shipping option available because it is the only service that requires a signature upon delivery. PayPal and eBay both require signature confirmation on packages worth more than $750.00.

Additionally (for both domestic and international purchasers), if you pay for the item using PayPal, there are two Priority Mail services I cannot offer, their Flat-Rate Envelope and Small Flat-Rate Box. Neither of these two services are trackable (or insurable), and they are therefore against PayPal and eBay's rules.

PAYMENT OPTIONS: EBay has made changes to their payment rules whereby (in eBay's own words) "Beginning in late October [2008], sellers will no longer be allowed to offer [any traditional person-to-person paper] payment methods on eBay. Only approved electronic methods will be allowed." As a seller, eBay now prohibits me from even using the words that describe what those traditional paper-transaction payment methods are. EBay strongly encourages all buyers to pay for their items by using PayPal (previously an eBay-owned company). I accept PayPal, and encourage you to use it, but I will not force you to use it. EBay's rules also state "A seller can accept [paper payments] from a buyer if (and only if) the buyer requests it. We will not take action against a seller who is trying to accommodate their buyer, complete a sale and be in compliance with the policy. Sellers cannot in any way solicit [paper payments] from a buyer."  So, let me be clear, I am not, in any way, soliciting you to use any payment method other than PayPal, I am simply informing you (the buyer) of all of eBay's rules, which state that if you (the buyer) request a different payment option other than PayPal, I can accept it.
