Hi,

 

I am new to photography, so please excuse me if my question is stupid.

 

I was wondering whether I should keep the VR and AF features on lens turned off when the camera is off or when the lens is detached. I know that if you keep the AF on and rotate the lens is not good for the motor. Could any please give me a explanation on why I should keep the VR and AF on/off when I am not using the camera. Usually is it safe to turn on and off these switches may times?

 

Also I have two lenses. I keep one always attached to the body even when it is in the bag. Is this safe, or should I dismount the lens always.

 

Thank you for your time,

Aravind

Hello Aravind.  Welcome to our forum.
I hope you enjoy your visits with us and we look forward
to seeing your photos and comments.

You’ve asked about a number of things, but for now I’ll direct you to a
very comprehensive article about VR (Vibration Reduction).
The bottom line is… Turn it on only when you need it.

Here’s the link with much more to say on the topic.

@Mandrake: Thank you for the article. It was really informativeLaugh.  I always put VR on. Now I know its not the right choice.

 

But the article does not seem to answer all my questions. I would list them down so that its easier

  • Is it recommended to keep VR and AF off when then camera is off / lens is dismounted and why?
  • Will toggling these switches (in general) a lot of times bad for the lens?
  • While keeping the lens in bag, is it better to dismount the lens or keep the lens attached to the body.

These answers are just a matter of my opinion.
I have not done specific research on them and would hope that you take the trouble to do so.

1.  It is my understanding that VR and AF are automatically turned off when the camera is
turned off so it would not be necessary to turn these off as well.  In general, I always leave VR off and AF on.

2.  Toggling these switches a lot would not be bad for the lens, but could well be bad for the switches.

3.  I always leave the lens mounted with the camera in the camera bag.  Changing lenses often result in dust
on the camera’s sensor.  It would therefore not be wise to remove them unnecessarily.

Thank you for the precise answer. I did some more reading and here are my questions.

  • Let me say in advance that I know I am not supposed to do this Laugh. When the camera was OFF, I engaged the AF, then I tired to rotate the focus ring. I tried the same with AF OFF. There was a difference in pressure that needs to be applied to rotate the focus ring. So I think the switch connects it to the motor even when camera is off. I am not sure whether this affects the motor badly.
  • In the article Mankdrake referred, and in some other article I have read, the electronics of VR was mentioned. If I understand correctly a set of lens/glass is moved inside to account for the camera movements. What was interesting was, these are fixed while VR is OFF. When camera is OFF and VR is ON, there is no current to move these elements, but would it be locked? If not while carrying wouldn’t it cause problems because of much shaking.
