If you don't know what that mod means or why the lens looks a bit funny, I've added a link below. Basically the aperture is de-clicked and a standard 80mm step up ring is included (also has the arriflex lens cap), along with a gearing for a follow focus.

The glass is perfect, no scratches that I can see and I'll even throw in a filter. Lens is still sharp as a tack and is super awesome for night shooting if you've got a micro 4/3rds camera.
It's negotiable to some extent and I do accept trades for camera gear (if you have a sachtler ace tripod or any sachtler fluid head, or a gh4, or lenses (pl mount, nikon f, and m4/3 mount) then I'm sure we could work something out with maybe some cash on my end.
