Make sure when you hold the filter to screw it on you don't squeeze too
hard.
This is easy to do and causes the filter ring to go slghtly off shape and
thereby aking it harder to screw in.
This causes you to squeeze harder to compensate and so it gets worse.
Make sure you hold the filter lightly spread the laod round the ring.
I suspect a few on and offs with a clean off of any debris will bring it
good.
