I want to clean the inner lens groups but when I remove the front group it comes out as an assembly and I can't figure out how to separate the lens elements. There are two holes in the barrel but I don't see any screws in them. Anyone know how to get the elements out?
There are How To videos on YouTube, but I recommend that unless you are highly skilled in disassembling and assembling lenses, that you send it out to be cleaned.
