I am going to be using a reversing ring. When the lens is removed from the camera body the f-stop goes to its smallest opening. The must be a way to keep the f-stop wide open when the lens is removed. Suggestions please.
Hi Ken. Not sure what you mean. I did some reaserch and found out if you hold down the PV button on the camera wqhen removing the lens the f-stop should stay open. it didn't. Humm??
