Rubbish ... not more!
These adapters do not allow to control the aperture of the
EF lens that they adapt ... instead, they come with their own
diaphragm ... well ... the bad thing is ... the diaphragm now is no
longer in the position that was originally intended when the lens
was constructed ... rather than that, it now is between the rear
element of the lens and the sensor.
