Homemade Compact Tripod ring 6 DC WR RE is

6 DC WR RE is a super-compact collapsible lens that keeps the camera's profile as low as possible

which actually does some really useful stuff: It cuts shutter lag time & increases burst rate when shooting stills

Can also be used in color enlargers in white light mode

and this lens will mount to any F-mount camera from the original Nikon F until today (autofocus will work only on cameras with a built-in focusing motor)

Homemade Compact Tripod ring 6 DC WR RE isThis is a compact wood and metal tripod, obviously homemade, with some rough edges, but pretty well done. The metal is aluminum; the wood looks like oak. Small: it stands about 66cm tall at full extension. There's a 1 4" thread up top for head mounting. Remember: this is made by Some Person, so it is not 100% mass production perfectly finished. Works well though.
