One Ring to Hold

Today, came next to the corresponding EF 50mm f / 1.8 II, also the lens hood.
I have read through the reviews this several times and had, due to the very streaky opinions a rather mixed feeling. So I grabbed the aperture of, looked at it and found it not quite as complicated as it is sometimes presented.

The metal ring is screwed onto the front lens is kept in a matt black and, according to the thing stable. It is not difficult to screw in the intended crease as eg a polarizing filter. I have avoided him to screw bombenfest to unscrew it easier to back (this was partly a criticism).

The actual screen is normal plastic, two opposed lateral pressure points as (eg for toilet cleaners) occur in some cases also safety locks, make a De-installation both simple and fast. Simply press the "" button, remove panel, ready. As complicated as it is partially shown here, it is not. An engineering degree or equivalent is certainly not needed.
