bill a. Posted February 12, 2007 Share Posted February 12, 2007 Bad, not meaning decayed, but is there a "wrong" foam? I ordered some form Micro-tools... what I got was 2mm thick (and I assume what should be used for mirror bumpers, not light seals), but has a much smaller/tighter bubble pattern that what I am accustomed to removing from cameras. It also feels "more solid" or "springier" (to use the scientific description). When the mirror impacts this stuff, if it is indeed "more solid", could I induce more mirror slap/vibration at "sensitive" shutter speeds (1/15, 1/30)?Did I get/use light seal stuff by mistake?

gary_watson Posted February 12, 2007 Share Posted February 12, 2007 The function is light seal more than shock absorption. I passed on sticky foam and went with thin, adhesive-backed felt for mirrors and door hinge seals.No problems after 5 years on a dozen or so Nikons.

Sanford Posted February 12, 2007 Share Posted February 12, 2007 I went several years with NO foam in a Nikon FM and could see no negative effects whatsoever. Link to comment Share on other sites More sharing options...

bill a. Posted February 14, 2007 Author Share Posted February 14, 2007 Excellent link... thank you. The foam I have looks more like light seal foam, and not what is in most of the images of mirror "stop"... looks like it shouldn't be an issue, though.
