I have recently purchased two different Nikkor lens whose lens hoods do not "click" when they are turned to the "locked" position. The lens hoods move and have even been known to fall off.
The effected lens are:
AF-S DX NIKKOR 10-24mm f/3.5-4.5G ED
AF-S DX Micro-NIKKOR 40mm f/2.8G
The problem is especially bad with the 10-24mm, as any camera movement or the wind can cause the lens hood to rotate, and it falls off on a regular basis. I have replaced the lens hood on this lens and that did not make any difference, so I would have to assume the issue is with the lens itself (or, a whole bunch of lens hoods that are defective!).
Other recent lens purchases have not had any problems with the lens hoods. Is this an isolated problem and I've just gotten unlucky, or is there something else going on here? Is anyone else having problems with lens hoods that do not click in place when in the "locked" position?
It just seems weird that I'd suddenly get two different lens with the same problem and I've never had a problem before the last 6 months. Any ideas what's going on here?
