Does this look like fungus to you?

Does it look like fungus? because without the light there doesn't seem to be any of these specks. Could it be dust?

EDIT: New development... Theres a spot that I CAN'T remove... could this be fungus?




There are also some pictures I took with it... if it helps at http://s234.photobucket.com/albums/ee312/NecroticSoldier/135mm/

Yikes... whatever it is... it doesn't seem to be on the outside... can dust get onto the inside?

Dust can get inside. And looks like there's some fungus, too

I would say it's just dust. My backup for that statement is this:



That's my lens, which doesn't have fungus. I think your photos look worse because of camera and or lens movement, maybe more dust too.

Can you focus inside the lens as vs the lens rings on the front. Would need to be a manual focus thing. But I say dust... (but I am an optimist)

I say it's mostly dust and possibly a little bit of fungus. And yes dust can get on the inside of the lens. If your inclined enough I would suggest that you take it apart and clean. I know for my Fujica lens the part with the fungus was on the outer part of the lens and did not require the aperture blades to be taken apart.

Why don't you try taking it apart (I suggest using a shoe box to hold everything) it look like dust and could be cleaned out. But is it having an effect on IQ?

I don't know how to take it apart sorry ;(. I have an album containing some of the pictures taken with it! Yeah, I'm not expert on IQ...

https://www.pentaxforums.com/forums/pentax-beginners-corner-q/72755-repairing...m-1-1-7-a.html Don't let this scare you, but if you really really love this lens maybe don't try this at home. But I say nothing ventured, nothing gained.
