RE: Looseness in front of lens

Hi Jon,

I have a tool for 49mm and 52mm lenses.
It is a metal cylinder with a gum rubber ring inside, works great.
Before I got that I used a wooden disc cut slightly smaller than the filter
size and a piece of the new non-slip rubber shelf liner.
Not as convenient but worked OK.
The trick is to get a grip without having to exert so much pressure as to
jam the threads, this is self defeating.
If you'd like to see a pic of the tool to get an idea of what to make let me
know.

Don

 I can't seem to loosen it using my fingers or small
 objects pushing on that ring. I don't know where on
 earth I could find a rubber stopper big enough to fit
 around that front element to be able to unscrew the
 ring that way. Anyone have any other ideas?

 Got to looking at my M135/3.5, it looks like it could
 use some work too if I could get its filter ring
 off... the hood doesn't like to stay in the extended
 position. What would fix that?

Assuming that the filter ring is in good condition you should be able to fix it 
pretty easily. The ring with the labelling on it screws out to reveal three 
small JIS cross point screws which secure the filter ring to the barrel. If the 
label ring is proving difficult to remove you may be able to press a rubber 
stopper sized to fit inside the filter ring on it for added grip and leverage.

I have some rather good photographic examples of looseness in front of
lens - but this is a family list
:-)
