Just got the Sigma 150 - 500 and the instructions say to make sure you shut off the OS before removing the lens or even shutting off the camera. Does that mean I should be shutting off the VR on the Nikon lenses also? I feel I am going to have a hard time remembering to do this :(

Its always a good idea to turn off anything using battery power before removing it from that power source! Your camera should always be turned off when removing a lens, flash, grip or memory card also.

Yes turn it off.

It is in me to always ask "why" rather than blindly follow rules. Not that I am questioning the rationalle but to know "why" really helps me to remember, also adding a bit more information of the how, that things work. Thanks

Because in todays electronics age, peripherals are in constant 2 way communication with the power source and to remove that communication stream without proper shut down can cause software glitches that may eventually lead to communication failure and hence to component failure.

Thanks, I now understand the "why". I will turn off power in the future.

Hell, 20 years ago, someone told me I should set my lens to manual focus everytime I add/remove it. I'm guessing this means nothing, but old habits die hard. I still shake my milk before I open it (grew up on dairy farm). :thumbup:

While I do not disagree with the conclusion I think it stupid to design something that requires such manual action every time it is done. Humans suck at reliably perfoming such actions.

There is perhaps a little confusion about the Nikon wording that was cleared up on an earlier thread. I think it may apply the same to the Sigma set up. The Nikon wording suggests that if you don't turn it off you can end up with a rattle in your lens. They assure you that doesn't hurt the lens but advise against it.

It turns out that what they mean by removing the lens "while VR is on" is that you would have to have the camera ane lens VR on and the shutter release halfway depressed while removing the lens. Fortunately you aren't likely to do that.

Also I suspect that turning off either the lens VR/OS or the Camera shuts things down good enough as well.

But I agree it is good practice to build the habit to turn them both off before lens removal and connection.
