Just a quickie...
I've just been given a 55mm Micro-Nikkor lens, suffering badly from oil. Apparently it's a common problem with this model, an early AI one, as the grease on the long helicoid seperates.
There's so much that there are beads of it on the ends of the aperture blades, and a drop on the rear element.
So... Do I need to worry about getting lighter fluid on the rear element? Am I making trouble with greasy marks and scratches? I certainly can't use it as it is, because it stops down at the speed of a catatonic slug!
Hints and tips for dealing with the droplet on the glass would be appreciated - otherwise, I've checked all the screws move, done the preparatory work, quite looking frward to working on something this modern!

For the purists, it looks to be this model, beautifully modelled by the lovely ebay...

Nikon is not a third-world experimental manufacturer and they don't make mistakes like that. Someone has had a go at your lens, Adrian. No doubt about it. Your lens needs a complete stripdown, the optics cleaning; the helix repacking with appropriate helix-grease and the iris-blades polishing with graphite and NOT oiling. The Micro-Nikkor is a superb lens and is worth the cost of a professional service if you can't do it yourself. |
