DIY: How to clean dust inside the Nikkor 24-70 rear element.
May 16, 2010

Well, I had 3 fairly large bits of dust behind the rear element of my 24-70 that bothered me. So I took a careful look at the lens mount structure and placement of the screws and decided to give it a try at removing the rear element for cleaning.
I discovered it's much, much simpler than I expected.

The rear element is permanently encased in a black metallic frame, you can see it, it's the black part of the lens mount that surrounds the rear element.

This frame is held in place by 3 screws, you remove them, lift the frame, and thus the rear element, off the lens.

There are no centering spacers, no electrical or mechanical connections, the frame is a separate structure from the mount contacts and aperture post. It just will slide out of the lens by itself with no hassle at all.

Now all you have to do is clean the dust, put it back into place and replace the screws.

You have to look around the mount for these 3 identical screws (they're the bigger ones) Feel free to try it, if you want. I am not responsible if you mess things up
