As far as saying I tried everything, I mean everything that involves batteries, buttons, switches, etc, without invasive surgery. I finally figured that because of shipping costs to send bck, plus those already paid I would have to have spent $90 on a $150 refund that might get to me this year. So, I just chalked it up as a bad (understated) experience, and I opened it up expecting springs and wires to shoot out all over the place.
I could see through the gate that there was an odd shaped obstruction of the light coming through. I looked between the lens and gate and saw a few different things, one of which was two pieces of metal tangled together. I didn't think this was the iris because it wasn't the traditional O type/ shape. I tried to untangle the pieces and when they were apart they started acting like an iris, opening and closing as the camera faced different directions. So, it worked on auto but still not on manual. Throughout this process there were so many times I thought the thing was going to break, everything is so small and thin. Frustrating to say the least.
