The differences are obvious in the views of front and top. Identical at the bottoms. However, on the back film chamber covers, do not notice any difference? (yellow vs. white)
I have not used or even touched this model, nothing special to me, except its dedicated rectangular-shape filter as found in its manual below. I believe that this filter is hardly to find today.
I believe that this 2X Macro Teleconverter (MTC) is made by the same manufacture of more commonly-seen Vivitar 2X MTC.
As I tested with a Pentax DSLR body, this Ricoh MTC with a Ricoh P mount is safe to use on Pentax DSLR cameras (see the last two images).
Actually, I shot the following images with a Pentax KA version of this 2X Macro Teleconverter (MTC, paired with a SMC Pentax A 50mm F1.4 prime lens). I believe, the same manufacturer made this kind of 2X MTC with various lens mount (e.g., K, KA, Ricoh P and...) and under different brand names (e.g., Ricoh).
As its name indicates, this MTC has two functions: to double your lens focus length and to work as an extension tube with glass for Macro up to 1: 1 (see my last two images in this ratio).
When I got it, there were 3-4 films left in the film package installed at the bottom of the camera. I tested it. It's easy to use. It have a installed flash, a close-up lens switch and a film counter. As I understand, this camera should come with a factory strap, which is missing from my 600. The only problem for me is where to find the 600 film package.
