Selling this to get money for an used GH1 body for hack/patch development.
This focal reducer has a serviced/tweaked optics for better corner/edge sharpness and fiting.
The distance among optic elements was adjusted to get better sharpness and the front and rear threads was shaved carefully to allow better fiting and all lenses can fit on it without touch between lenses and allows focus on infinity with all lenses, even the 20mm which has most pronounced rear elements.
You can use Canon FD and also Nikon lenses with the mount adapter, see photos.
Asking 100 usd for both pieces + shipping. PM me about your country to calculate shipping.
