Nikkor 35-70mm D f2.8 AF Lens and the D-70 I am about to purchase a Nikkor 35-70mm D f2.8 AF Lens. I have the D-70 . My concern is that the push/ pull zoom on the lens, may create or intensify dust issues ? Has anyone tried this lens with the D-70 ? I have one body and cannot afford a second.

Suzanne, since you have been unceremoniously ignored all this time I thought I'd offer a response. The zoom action of the lens should have zero impact regarding dust issues. Remember that the camera body, once the lens is in place, is light-tight, and you can rest assured that it is fairly dustproof as well. A little weatherproof, even - not that I'd dunk it in water. The point is that with the lens on the body zooming and focusing (which also moves lens elements back and forrth in some lenses) will not create such a powerful vacuum that dust particles from the surrounding atmosphere will get pulled into the infinitesimally small gap between the lens flange and the body flange (that is, where they connect). So worry not about using that lens. Dust can be a problem when you are changing lenses, if there is enough particulate matter in the air some might get into the shutterbox and the natural static charge on the CCD can attract it. But while the lens is on the camera - no worries (to use that badly over-used colloquialism).

Suzanne, You may be overlapping two different dust issues. I've heard opinions that push/pull zoom lenses tend to be more likely to allow dust into the lens barrel than lenses with twist zooms, or fixed-length lenses. But this only refers to dust inside the lens, which generally does not show up in your images. Digital SLRs are also vulnerable to dust getting on the sensor when changing lenses. I've been told that turning the camera off before changing your lens can help, since it will remove the static charge on the sensor.

I forgot to add in that I don't think you should let either of these dust issues keep you from buying this lens. Chris
