    Hi, many questions…
    This should work on an ASI290MINI with a CS adapter, right?
    Can you tell me the dimensions of the lens, especially diameter?
    Also, I see 3 controls: focus, zoom, and what is “O – C”? Iris control?
    Can you tell me the closest focus distance at maximum zoom?
    Thanks!

    Could the lens be used on a 174 sensor on low resolution mode? For example, in 640×480 I imagine that the effective sensor area is around 1/2.4″, so the lens should be able to illuminate most of the image area. Is that right? Would the back focus and dimensions fit for the 174MM or 174MC models?

      Yes, you are correct, ROI will reduce effecitve area. 174mm and 174mc have 17.5mm back focus for C mount lens using our CS-T2 mount adatper(because of the back focus of 174, the cs mount only can use a C mount lens)

    Will it work on a cool cam using a 5 mm spacer? I can’t find a c-mount lens on the site, they all seem to be cs-mount.

      no, CS lens cannot work on C mount
      but C lens can work on CS mount with the 5mm spacer

      no, the back focus of cooled camera is 17.5

    Can this lens be focused, as in closer and further away, or does it just have a fine focus adjustment like the included fisheye type lens on the ASI 120MC Also is this for sale from the USA?

    Sorry, I meant at 2.8mm, not 12mm. I would imagine that the field of view is smaller than with the 2.1mm.

      yes, the field of view 2.8mm lens is smaller than the 2.1mm, around 100 degree

    Hi, how does this lens compare to the 2.1mm lens regarding field of view? Do you get 180° on ASI224 when used at 12mm? Thanks
