easy precautions prevent IR leakage to affect pics for long exposures

Marianne :

The best solution, at least for now, may simply be awareness of the
effect, so that the user can make informed choices regarding lenses
for special applications.

Is there such an application? Who needs VR or AFS for a 30 minutes exposure?

However the important point is taken that users should turn off VR and AF for very long exposures, and the latter using the lens switch on specific lenses. Thank you for confirming the problem on the 70-200 f2.8 and the results of your investigation.

Using the AF switch on the camera to manual * should * be enough. So I'm ready to call the fact that the switch on some lenses must be moved as well a design flaw, but a very small one, with an easy workaround. IMO MaxKphoto's angry comments at Nikon were quite over the top... Also, IMO again, the subject of my post is better worded.
