Sorry to add my 5-star critics. Have the 700D with the STM - lens and because the diaphragm does not fit. It has generally too much play and also does not lock. That would be to get over, but because it is so vague, it rotates very loose and would not be sitting on the lens long. As you can describe it accurately with 100%, I do not get it. And as more buyers criticize this, there can be no series dispersion.
Small Optical flaw, there is no marker available. That would not bother me, but at the current aperture, this is always present.
