The camera and the bellows in the images are NOT included. What you are buying is a 100mm Achromatic Meniscus Doublet made in France 90++ years ago, adapted to be used with Nikon 35mm F mount cameras including digital SLR's and Manual Focus Nikon film cameras.
It's just the original antique french doublet mounted into a Nikon body cap. Simple as can be. But OH! the images it can create for you. It has to be used with a macro bellows that can accept F mount bayonet. Or take the doublet out and adapt it to your micro 4/3 or other brand system!
The color images were made with a Nikon D200. This antique doublet would also work on 2 1/4 square medium format and 6X7 if you have a way to cobble it onto your system. TTL focus a must. There's a learning curve.
