P67 - reduction of mirror slap vibration

[milco_van_klingeren]

Are there people that have experimented with small pieces of foam in the P67 body to reduce the vibration and noise produced by the mirror ? In my opinion it must be possible to improve this in a easy way.

The metalish sound of the slap is disturbing me most.

I've tried mounting foam in many different

configurations on the upper box housing.

There were two problems of note, either of

which were serious enough to nix the idea.

 

<p>

 

The first problem is that the mirror

assembly includes a geared cam that

must ride to its end before engaging

the shutters release safety. The foam

would block this action and make the

system prone to jamming.

 

<p>

 

The second problem was that copius

amounts of foam seemed to have little

material effect on either the noise or

vibration levels generated by the sys-

tem.

A third problem, only applicable to fr-

ont or rear edge foam mounting, was that

the foam would mark the mirror surface.
