VR affecting battery charge
Jun 18, 2022 09:44:27 #
Robertneger just posted a question about using VR for landscape photography and several respondents said they leave their VR on, all the time.
I used to leave mine on but it seemed like the battery would drain faster when I did that and it would even drain the battery over (a long) time with the VR left on and the camera turned off, just sitting in my camera bag. Does anyone know if the electrons are still flowing with VR turned on and the camera turned off? Or does shutting off the camera also shut down the VR?

It would be kinda stupid for manufacturers to not have the "master" on/off switch turn the entire camera off...
What would be the benefit of having VR still active when the camera is off?

It's your imagination. The VR is engaged only when the camera is actively focusing. It does not create a long-term drain. It doesn't not operate under it's own control.

More information than anyone would need, but here it is. I don't think addresses the question you posted, though.

I use BBF with VR turned on almost 100% of the time. As long as I have the BBF button pressed I can hear the VR motor doing its thing and received the benefits of VR.
Do I lose the VR benefit if I Release the BBF button to recompose? I would think so.
{It does not create a long-term drain}
I will disagree with you about the VR circuits not using power if VR is not active & camera turned on. However, I believe the power drain from the VR circuits would be miniscule compared to the camera circuits drain. My wife is always telling me I'm wrong, so again I could be wrong.

Not engaged when the shutter is <half> pressed?

In my experience, and with my cameras, VR reactivates when the shutter button is half-pressed even if shutter focus is disabled.

Just keep in mind that all batteries discharge even when not in use. Most cameras have a little battery that keeps the clock in it working even when the main battery is removed. They are usually good for about a month without the main battery being inserted and charged up. Let the main battery go completely dead for over a month and you will likely have to reset the date-clock.
Many things we use today have a continual current draw even when not being used. On your car, it’s things like the CPU memory, radio presets, clock, etc.
Even without the continual current draw, batteries will slowly discharge all by themselves. With the wet cell battery in your car, it’s about 1% per day. That’s 1% of the total charge at that time, meaning the daily volume of loss decreases as the battery gets weaker. Also, a car battery with a dirty top loses more than a clean one. (Sulfuric acid deposits.)
I highly doubt the VR draws any power when not in use, but the clock battery is a continual current draw. I can’t remember what camera it was, but the same little battery also powered the computer memory. If the battery went dead enough for the clock to need resetting, I also had to reset all of the ISO, white balance, etc.
So while it’s unlikely your VR lens is killing the battery, you’re not crazy in thinking that something is.

Lots of opinions very little to corroborate them...
While I have reservations that that there are enough technical savvy photographers on UHH to actually appreciate what Thom brings to the table on his extensive analysis which he has continuously update over the past decade.
Thom was a senior editor for a very widely read and revered Photo Magazing for many years.
To this end I would suggest you bookmark his dissertation since it is extensive and actually enumerates which of Nikon's VR iterations function on a myriad of their Nikkors.
What Thom shares here is that there are not any "rules" or "best practices" for VR but rather a kaleidoscope of parameters to keep in mind each of which may only be germane to a small subset of VR optics. Nikon continously advances the technology as it moves forward. This has resulted in newer Nikkors rising the performance bar...
The most scary takeaway? Since i'm certain few will actually study Thom's analysis.
If you disconnect a VR optic while the VR system is still spining down you have placed you lens in serious harms way... i.e. yes you can trash a VR lens by removing it too quickly from your camera...
From experience I've noticed some high end Sigma's optics are slow to "park" there floating elements. Sigma actually cautions that it's OS takes a second or so to spin down... And since Sigma was sued by Nikon for copyright infringement on it's VR I'm a believer here. I've always allowed my 50-150mm f/2.8 HMS OS IF Sigma to spin down prior to removing it... enough said
Here's Thom's wisdom on VR (which I've study many times over the years (he updates it constantly))

"Spin down"?
What's "spinning"?
5 seconds? 30 seconds?
What are you waiting for to become "stable"?

When I got my first mirrorless camera (a Z6) I mounted it on an F-mount 800mm AF-s, VR.
As long as the VR is turned on, it is active when the camera is turned on. I could hear it when the VR and camera were turned on. I contacted Nikon at the time and was told it was normal. That lens has never seen a digital since.
There may have been updates since then. For now I only use the few Z lenses I have on the Z cameras.

This is also the case with my 70-200 F mount on the Z6 but have enough batteries to deal with it for now.
