Otherwise known as Purpleheart, Peltogyne is an extremely dense and water-resistant wood. It is ranked one of the hardest and stiffest woods in the world. It's so durable that it's been used for such demanding applications like sailboat decking.
The trees themselves are prized for their beautiful heartwood which, when cut, quickly turns from a light brown to a rich purple color. Exposure to sunlight slowly darkens the wood to a brown color with a slight hue of the original purple. As the wood is exposed to UV light (e.g. sunlight) for long periods of time, the purple color slowly changes from a light purple to a subtle chocolate color.
11MM diameter is universally compatible with all cameras. 14MM diameter is compatible with the majority of cameras, but is not suggested with medium format cameras which have the shutter button next to the lens (ie. Hasselblad, Mamiya, and Rolleiflex).
REG THREAD compatible with majority of cameras having a threaded shutter button. (ie. Fuji, Leica, Canon 35mm Film, Nikon 35mm Film, Pentax 35mm Film)
FAT THREAD compatible with Leica M3. medium format Hasselblad, Rolleiflex, and Mamiya cameras.
