Thread: Calculation of MFD and Magnification factor with macro tubes

    Default Calculation of MFD and Magnification factor with macro tubes

    Hi,

    Does anyone know how exactly to calculate the MFD and magnification factors of lenses when used in conjunctions with extension tubes?

    I saw some excel sheets online for use but they were quite rigid and looks very messy.. So I was hoping to get some explanation from someone who is familiar here..

    If you know of a good resource, kindly point me over!
    I'm ok with (complex?) math too!

    Thanks!
