Hi there! Came across this thread as I just got myself a K3. I’m using it for the first time next weekend and when I’m looking through the viewfinder now with no film inserted, I feel that something needs to be cleaned. I cleaned the lens back and front. But still looks like some dust or dirt is somewhere. Is this normal? Do you suggest taking off the front plate to clean the mirrors or prisms? Im scared to accidentally clean something too hard but I just want my film to come back as clean as possible. Thanks in advance!
