Quote:The best advice is to leave it there. I have ruined 2 x lenses by chipping them in an attempt to disassemble and clean them. However, the problem is that you will 'know' it is there and if you have even slightest obsessive personality like me it will annoy you and it will keep on annoying you. The obsession is wanting to do it and the compulsion is acting on that obsession.The desire to clean it will become strong and you will lie awake at night thinking about it, so against all sound and sensible advice you will end up cleaning it either professionally or reading up on how to do it yourself correctly. If you attempt to clean it yourself and destroy the lens, well you will learnt from your mistake and you will have ignored the sound advice not to do it in the first place. So please ignore my obsessive advice and listen to the sensible advice. [If you can ]Chris

Quote:Just to limit my liability all I'll say is that the key to gttting at the lens cell is figuring out how to detach the sliding dew shield, the real 'ring' of the shield(part towards focuser) is held on by glue drops. Once removed a lot becomes far more simple to see and understand. The cell has 4 'sets' of screws one for each element approx 90* opposing. The cell itself screws into/onto the CF tube.
