I wanted to actually filter for my M.Zuiko 14-42, but I ignored that it is for the Zuiko (without M.) 14-42. But it fit perfectly on my M.Zuiko 40-140 - no conversion is therefore necessary. In my opinion, a complete replacement for the original - it engages with excessive force and can be removed with as much again. What is important, because you can save space flipped the lens outer bayonet mount it.
