    I have used it with 135mm, giving it some serious vignetting which i'm not comfortable with...:P
    Current: 550D + EFS 18-135mm IS + EF 50mm f1.8 II

    When using with the 18-135, should be using towards the tele end. Magnification increase with increase in lens focal length for diopter.

    Magnification = (focal length x diopter value)/1000

    hence at 125mm, mag = (125 x 8)/1000 = 1x
    and at 50mm, mag = (50 x 8)/1000 = 0.4x
