Sup guys got my usual daft questions for you. I just got a soldering iron and im about to try my first project. Soldering the cable of my auto iris lens to the small plug. I bought it like 6 months ago but as it required soldering it didnt get used Ive been reading how its done and i have a question. The lens i have is a computar 3.5 - 8mm. Now it seems there is 2 different ways to wire the plugs based on if its a DC lens or video lens. Heres some pics on hows its done. I think mine is a video lens. www.supercircuits.com/media/docs/pc165hr-manual-nb.pdfBut my issue is one of my wires seems to be cut short. The green wire. Is this not used? Kinda confused. Any chance one of you electrical geniuses can hold my hand here and tell me what wire goes to what pin number please and if i need this green wire or not

1.Video drive lens operates by the camera video output signal. It can be easily recognized because , comparing with DC drive, it has a 3 wires connection (video, power, ground). Its operation can be controlled by ALC and level potentiometers. The connector to the camera is normally not supplied with lens, because there is no internationally recognized standard on it and every single camera manufacturer can have a different standard.
2.DC Drive lens operates with 2 coils: driving coil is to move the open/close iris operation while damping coil is used to break iris movement (consider it as a reaction to driving coil operation), thus controlling the stability of iris movement. This lens has a 4 wires connection. Connector can be supplied with lens being a standard on most cameras. This lens is cheaper than the video drive type, lacking the built-in amplifier which is incorporated into the camera

Yeh man for a cloud cam. I bought a cheap ring clamp thing that fits round the OTA and allows a camera to go on top.
I was keen to get this lens working to have a play about with it before dropping £30-40 on a decent 5-100mm lens.

Hi Hoops, I was sent a Yomano lens just like your Computar with the ALC and LEVEL buttons on it. What are they for and how do you use them? I was also sent a small board cam with 3 wires and brief instructions that I don't understand. Can you explain what it means? excuse the bad piccy.
