It is not often you get to say you've held or used a 4x5 twin lens reflex camera. Maybe you were lucky enough to know someone who handed you a Gowlandflex that one time, or perhaps you stumbled across a Newman & Guardia Twin Lens Pattern camera at an antique store (what a find!)... Either way, users of the Tomiyama Art-Flex 4x5 certainly do belong to an exclusive club.
The Art-Flex 4x5 was produced by the Tomiyama Seisakusho Co. sometime during the 1960s. It is possible that these cameras were also exported as the Color-Flex 4x5 by Chiyoda Sankyo Co., a company with which Tomiyama had a close relationship. The design of the camera is simple. Take a sturdy aluminum box, attach a front lens standard holding identical lenses, and connect that standard to the camera body via bellows. Allow for rack focusing, as well as top-down waist level viewfinder for focusing and composition, and you have something that is fairly similar to the early Mamiyaflex TLR cameras, just a whole lot larger.
The only lens mentioned for this camera (that we could find in our research) is a Fujinar-W 150mm f/6.3. However, we were then paid a visit by our customer, Minh Thien, who brought in his Art-Flex 4x5 with a pair of Mamiya-Sekor 105mm f/3.5 lenses. Perhaps it had been specially modified for this lens, or perhaps Tomiyama made a small selection of interchangeable lenses... if we ever find out, we'll fill you in.
Count yourself fortunate if you happen upon an Art-Flex 4x5. Enjoy it, treasure it, use it.

Minh Thien's Art-Flex 4x5
You know it is going to be something good when, you are in the back of the store working away and one of your co-workers runs up and says, "You may want to come up front and see this camera." Sure enough, what was awaiting on this particular day was this Art-Flex 4x5, a 4x5 TLR camera smaller and lighter than the Gowlandflex. We had never seen one of these odd cameras before and, the best that our research turns up, is that they were made by a Japanese company called Tomiyama, most likely between the 1960s-70s. It is a pretty slick camera, with interchangeable lenses and ground glass focusing either via waist level finder or off the back of the camera.⠀

A big thanks to Minh Thien for bringing this camera in to share with us!
