Title: Zoom air movement and dust issue
Post by: Zang on May 15, 2020, 15:14:21

Hey ya!

I notice some old zooms are causing a lot of air movement. I place the rear mount close to my face and do the zooming and I can feel the "winds" blowing :) How serious is the sensor dust problem that those zooms may cause?

Cheers,
Zang

A couple of years ago I had a serious dust problem with a brand new D4s body; my NPS salesmen pointed the finger towards my Nikkor 28-300 mm f/3.5-5.6. I took about 200 pictures, and, between each picture, made a dozen of quick rotation movements on the zoom ring. End result: no dust was sucked into the body as a result of the aforementioned.

(*) the problem was due to a D600 like shutter mechanism, which was replaced in the end.
