Hello Sylwester: I sent some messages to the list about the problem you mention. When you screw a filter to the back of the lens, the mirror in the MZ-S, MZ-5 or MX gets stuck when it is returning to its normal position after having fired the shutter. If you press the bayonet release button and turn the lens slightly, it returns to its prefire position. It doesn't get stuck in bigger bodies such as the Z-1 or SFX. Perhaps they have bigger mirror chambers. In fact, I am thinking about selling this lens, as I don't use it very often and a 18 or 15 mm. would suit my needs better.
