Re: Pentax 67 pentaprism issue
I'm not exactly sure how the 6x7 pentaprism is constructed, but if there's some kind of corrector glued to the bottom the way lens elements are sometimes glued together, it might be something that's got into the glue. "Bugs" don't eat glass, but they will eat glue. On 12/8/2016 1:06 PM, Gonz wrote: It looks a little symmetrical to me because it is right where the top edge of the prism is.

Not so sure it is fungus. Have you seen the movie "Arrival"?

Are there any tricks or hidden parts to worry about when disassembling the housing for the prism? On Mon, Dec 5, 2016 at 11:44 PM, Paul Stenquist wrote: > Yeah, it's probably just debris.

Re: Pentax 67 pentaprism issue
It looks rather too big and surprisingly symmetrical for a fungus. If so, that can be cleaned easier and hopefully with no permanent damage.

Re: Pentax 67 pentaprism issue
Looks like it. Sunlight or hard UV to kill it. Normal lens tissue to remove the organic material afterwards. There will always be a mark, though, and not the interesting or amusing kind. > On 06 December 2016 at 01:23 Gonz wrote: > > > Fungus? Can I clean this?
