The use of VR/IS enabled lenses or in-body stabilized mirrorless cameras is not mutually exclusive to using a tripod.

As much as I hate lugging tripods, I have to agree. The first examples I can think of are shooting the moon or sun.

Correct. Many new lenses suggest leaving VR on when using a tripod.

Alas, my Z6 says, regarding VR:

“To prevent unintended results, select Off when the camera is mounted on a tripod unless the tripod head is unsecured or the camera is mounted on a monopod, in which case Normal, Sport, or On is recommended.“

I don’t think I can enable lens VR with camera VR off. I know I can turn lens VR off with camera VR on.

On further checking I don’t think I can turn off lens VR without turning off camera VR. I read that the lens switch takes over the camera control. I’ll have to test it.

Your assumption that posts in Links and Resources are not looked at is incorrect. Maybe you don't look in L&R but that doesn't mean that others don't. There is a lot of good information in L&R and it is worth visiting. Give it a try, you will also see that more people than you imagine are there looking too.


More than an assumption. There are over two million posts to the Main Photography forum. Only about 100,000 to Links...including all those shunted there by the bot.

Might want to check this out for the impact VR has on a 24-70 mm lens.

Check DXOMark:

Looks like they agree the VR is a little less sharp.

dpReview just published a comparison of the latest Sony and Nikon mirrorless cameras image stabilization systems. The results are interesting for a number of reasons and likely typical of other current generation image stabilization systems.

They show that the old rule of thumb for 1/lens mm for full frame was a pretty good rule for full frame cameras without image stabilization. But image stabilization blows that away. The test also shows the utility of taking multiple images and picking out the sharpest ones.

I’d post the link but then the thread will get moved to links and no one will look at it.

I’d appreciate discussion of the test and results. What should our new rule be with image stabilization?

Image stabilization is good for exposures with long lenses at slower shutter speeds than 1/focal length of the lens. BUT, after a shutter speed of say 1/1000 sec. , image stabilization is not needed, image stabilization takes extra battery power so I only use it if I am shooting at a slower shutter speed than 1/750 sec. on my D500 with 200-500 lens.

Right! I frequently do that.

In those cases VR still helps to stabilize the image in the viewfinder.

My evidence is anecdotal but I am convinced the IBIS system in the new Nikon mirrorless Z6&7 is topnotch. Yesterday I posted a set of river/stream photos that were all handheld at shutter speeds that varied from 1/40 sec to 1/2 sec. The latter (last photo in the series) I wanted to show motion in the water and I braced my hand and forearm against a tree and got the effect I wanted with the stationary rocks and leaves all quite sharp. This was with the Z7 and 24-70mm f4.0 lens at 70mm using autofocus set on the central rock.

The shutter speed is also dictated by the subject you are shooting - whether you want some blur or a lack of it. The guideline of (1/focal length) is assuming you have a stationary subject and want reasonable sharpness due to camera/photographer shake or motion.

Correct. The guideline was to limit the effect of camera movement, which is all VR deals with.

Subject movement is another matter and may dictate shutter speed. But that isn’t the topic here.

OK, but it does not improve image quality. And, it is a drain on the battery. A big drain.

Looking at the forums here I rarely see the discussions so narrowly focused to just precisely the topic...and it is closely related.
