    Hi,

    I understand the STL6303E back focus length is 43.18mm WITH the 2" nose piece attached.

    Can you please tell me what the back focus length is WITHOUT the 2" nose piece attached?

    Thank you for your help.

    With kind regards,
    Brian

    The base of the 2" adapter is 0.20" thick.
