In general, apart from the fact that I had to tinker with adjusting the focus, Has some pros: 1 2 MF mode, without fear that you will twist the focus motor to it (I turned the 50mm 1.8 II Canon head like this)) 3 although 50 1.8 - the maximum resolution of glass is achieved, and at 50mm 1.8G at f5.6 4 the aperture itself and bokeh) Has cons: The disadvantage is that almost all specimens have back focus, gradually picking up (adjustable in the camera from -20 to +20 steps), because in our case, the most accurate result was obtained, immediately without changing the object and without changing the distance to the object, I move the lever on the lens to the MF position, turn on the Live View mode, then you again adjust + my copy has a value of -14, this is a fairly strong back, not kidding, it's time to produce a quality product.
