Re: Loose front on 50/1.4

[Alan Chan]

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?  :-)

I'm sorry Alan, but I'm not getting it. Could you please explain further?
What is a retaining ring? :-)
English is not my first language.
