  1. Hey i just got my Speedbooster yesterday and the "Sigma 18-35mm f1.8" works just fine but the "Sigma 30mm f1.4 EX DC HSM" seems to have a problem.
    The Maximum Aperture still is f/1.4 when it should be 1.0 or am i wrong?
    I read on their website that some Zoom Lenses might need registration for maximum aperture, maybe this one as well even if its a prime?
    Or is it just not fully supported?
