English is not my 1st language either. :-) When you look from the front of the lens, the edge of the front glass is actually covered by a large ring which is as wide as a 49mm filter thread. That is the ring should be removed. For example, for the M50/1.4, "PENTAX-M 1:1.4 50mm ..." is printed on that ring. Got it? :-)

Ah, okey. Now I get it. How the he** do I remove this without damaging the glass?
You use something actually made for use around glass lenses, not something made from who knows WHAT rubber-like material that has foreign material in it that will make nice semi-circular scratches on the front lens element...
You can be absolutely sure the tapered gum rubber lens ring removal tool from Micro-Tools is abrasive free on purpose!
How big a risk-taker are you?
