Good afternoon. The Canon CL 8-120mm lens combined with the Runcam eagle 2 course camera, 1 / 1.8 matrix. He removed the brains from the lens, the diaphragm is manual. Image picture on tv / monitor via A / V in. The result pleased the night with a starry sky and a daytime search for objects (ufo) in the sky. No hot mirror filter. I use the day Ir 850nm 72mm. The best result would be with a runcam night eagle 2 camera with 0.00001lux. Good luck to all.

I also found this in some Russian forum and translated it. If it’s not the same dude who did this in the photo, then the solution is very similar. -

“cool lens, very underestimated. And the whole problem is in the brains of the lens, it understands only the video camera - its mother.
But it’s fixable.
I solved this very simple problem.
I disassembled, threw out the brain board, after biting out the 7-pin connector from it, threw out a kind of electric magnet or a stepper motor (dunno) - a diaphragm control with a bunch of wires.
By the way, the diaphragm without supplying a voltage is always closed. Brought out the slider to control the diaphragm manually. Two engines: focus and zoom soldered to the 7-pin connector and connected to the block. I made an adapter with 4 motor control contacts.
This lens is for 1/2, 1/1.8 matrix size. As a camera, I use a runcam heading for a copter with an analog video output directly to the monitor. Similar lenses for outdoor cameras are much more expensive. On ebay they are given away for a penny. If you do not want to bother with the adapter, take the converter and remove it from there. Something like this.”

I hope this helps someone.
