of course not la! No AF, no Aperture control on EF lens, but still good if you like to use the lens wide open, or you can pre-set the aperture with a Canon Body (DOF Preview) while unmount the lens. Then your lens would stay at that aperture..! With 4/3 lossing so much DOF, it's actually not that bad when using a tripod, and manual focus.. or macro works!
I have also tried my Lens-Baby on it too!! |
