      183 sensor is too big for fisheye lens.

    But it says 1:1.2 on the front ring! Is that wrong? The light gathering capability difference between these numbers is huge; an f/1.2 lens gathers about 2.8 times more light than an f/2.0 lens! So which is it?

    Also, what does the “IR” signify? That it is transparent at IR wavelengths, or that it cuts IR?

    Thanks!

      290mm-c work with CS mount, will support C type lens, because the back focus is 17.5mm

    I’d got one for a ASI178MM-Cool and can’t reach focus. I used the T2 To CS or C adapter adapter
    I appears to say it should work with the ASI178MM what am I missing

      this lens is CS lens, cannot be used on our cooled camera whose back focus distance is 17.5mm
