Old Nikkor lens
I have an old (12 years) "AF Nikkor 35-70mm" lens that came with my Nikon
F801s. I guess it's the standard lens they fitted on that camera when they were sold. Now it is almost impossible to turn the zoom ring on the lens. It's all seized up. Is this a common sort of problem with old lenses? Is it generally fixable (a "lube" job?) - and how can it be fixed (do it yourself, or a camera shop)? Thanks , Peter |

I have that lens too, on my Nikon 8008 (the American ID for the same
camera). It should not be a common problem. (Mine is fine.) I would guess it resulted from storage in less than favorable conditions - maybe high humidity or dampness. Or possibly sand got stuck between the rings. Home maintenance of lenses is something that should be undertaken with great care. There is a book - vol. II of Camera Maintenance and Repair [I think - I have it at home], that is probably a good investment for anyone wanting to undertake their own repairs. One thing for absolute certain. DO NOT USE OIL ON A LENS (or shutter). If at all in doubt about your ability to do the job, have a camera shop send it out for repair or go directly to a camera-specific repair shop. In all likelihood, a good cleaning will solve the problem. Francis A. Miniter Peter K. wrote: I have an old (12 years) "AF Nikkor 35-70mm" lens that came with my Nikon F801s.

I took my lens apart (but not *completely* down to the shutter mechanism), cleaned out the grit and sand which had accumulated over the last decade, and now it works fine! And I even managed to put it back together with no pieces left over and all the screws in the right place. There is some sort of lubricating material in there. Maybe not oil, but some sort of special grease or something? Anyway, thanks again, Peter |

If it is the "shifty" aperture lens, it was only $70 new (the only Nikon
lens I ever bought that I dumped, and quickly). I think the cost of repair will FAR exceed the value of the lens. If you really like it, pick up another one. If it is a "loss", you might want to pick up a book on lens repair and just take the thing apart for the experience so you'll know how they put the lenses together. "Peter K." wrote in message k...

Good thing you managed to fix it. Lenses typically use various viscosity
"damping" greases. "Peter K." wrote in message k... "Francis A. Miniter" wrote in message ... I have that lens too, on my Nikon 8008 (the American ID for the same camera).

I have no idea about the lens (or what a "shifty" aperture lens is). It's just the standard (I guess cheap/basic) 28-70 zoom that was fitted to the camer when I got it over 10 years ago. I've never had any other lens on the camera. In Denmark (where I live) I have been told that a replacment lens would cost the equivalent of about US$600. (Although a Sigma for example would be lot cheaper, say $300 - where can you get a lens for $70?!). But as you have seen I did manage to clean it up and get it to work again. It was indeed interesting to take it apart and see some of the inner workings. Peter |

Just following up to clear up my terminology in case it confused anyone.
When I referred to a "shifty" aperture lens, I meant a lens whose aperture varies with focal length rather than remaining constant. I don't see the correct terminology used much today, so I avoided using it. More correctly, a lens that can have its focal length varied continuously but does not maintain a constant aperture when doing so is a varifocal lens. A true zoom lens maintains a constant aperture throughout its range of focal lengths. After reading your previous post, it sounds like your lens is the 28-70mm f/2.8 true zoom lens, a nice lens that would even be worth paying to have fixed. But I never heard of it being bundled with a camera body as the lens was somewhat on the pricey side for a bundle deal. "Peter K." wrote in message k... "George" wrote in message ...

Funny, I thought a varifocal lens was one which may not maintain focus when the focal length was changed where a zoom lens is one where focus would be maintained. I didn't think that aperture sizes came into the equation.

You just might be right on this. It has been a looooooong time since I last
even heard the term. I just know that since I do some studio photography (as a hobby) that non-constant aperture zoom lenses are a PITA. "Ronnie Sellar" wrote in message ...
