    Default Supercircuits (SC) PC23c Survellience Camera and 35mm Lenses



    I have a Supercircuits (SC) PC23c survellience camera that takes a
    C/CS camera to lens. I have an (Orion?) adapter that gets me from C to 35mm but
    this adapter ends up making the focus a little off. Is there some
    adapter that allows variability in the attachment so the focus is
    correct? SC sells a variety of different focal length c/cs lens but at
    $29 per lens it gets a little tricky to cover a good range of focal
    lengths. I have several old 35mm lenses with fixed and variable lenses.

    Does this mean that the camera will not reach focus at infinity or simply that
    it does not agree with what the lens is telling you?

    The difference between C and CS is where the image plane is located. I believe
    the PC23C is C-mount; perhaps your adapter is actually CS? Normally, you can't
    convert a camera from C to CS, but you can convert it from CS to C, using a
    simple spacer ring. You might just need a different 35mm adapter, one that is a
    few mm thinner.

    You don't want to go through the 35mm adapter but rather just go directly
    from the C to the 1.25" tube.
