Hi,

I have a lens with some suspicious marks on the probably inner & rear optic/s

You answered you own question in the pictures: yes, it's fungus.

Can it be removed? Yes, but the lens coatings will be somewhat affected. Even after removal, it always leaves some traces.

At this stage, it should not interfere too badly with image results.

Cheers,
Jean-Louis

Thanks Jean-Louis,

I guess I am getting quite good at spotting this awful stuff - but I wish I hadn't :-(

That would have been the lens of my dreams.

It has other issues too - the reflex viewer is 30% opaque, impossible to see what is causing this, more fungus? Grime? I don't know. I'm begining to think this lens is a lemon since it was sold as being in good condition. To clean up this baby would probably cost some and , as you say, the optics would be affected by the cleaning.
