MFdof - 70mm (medium format) dof adapter with macro glide

A DIY project - the goal was to make a lightweight adapter with macro glide.

Main features are: 55x41mm frame size, expandable body (macro glide) for filming very close objects with any medium format lens and maintain visible dof even with wide-angle (fisheye) lenses.

The good things about this adapter are: lightweight, big GG (possible less grain than usual in 35mm), and only 15mm distance from the camera (tested on Sony HDR-FX1 which has, in short, poor macro capabilities). No vignetting or hotspot (hardly noticeable).

I am getting best results with a beattie, but also looking for other GG types, along with other camera types to test it (I am stationed in Croatia/Europe).

A m2t version also available (600MB)

The footage was shoot with HDR-FX1 but I am looking for any other camera in my region to test adapter, so if anybody is interested, please mail me.

Unfortunately I didn't make any usable drawings so far. The main thread is 72mm. The screw has a hard gum part at the very end and it holds the adapter in desired position.

Thank you on your comment!
 
Nice photos, I am interested in the overall construction design and the cost overall plus the parts used. Hope you can get around to listing all that. Good job!
