I bought one of these second hand some time ago and I recently noticed some kind of defect on the inside or the rear element. I have no idea what it is but it looks like I might be able to clean it off if I removed the rear element.

How do I do this? It appears to be mounted in a ring with a pair or notches on opposite sides. I tried using a wide, this piece of metal as a screwdriver to try and unscrew this ring but it wouldn't budge.

Any ideas would be most appreciated.

Hi Coops,

You'll may need a lens spanner to remove the rear element (it's been a while and I can't remember).

Try this webpage - it may help - http://homepage.mac.com/jpelling/page11/page11.html
