    B&H says that if you turn on image stabilization with the camera mounted on a tripod it can create a "feedback loop" that damages your hardware. What the hell are they talking about? Why would the camera care if it's on a tripod or not? The sensor or lens gets moved to cancel out shake, regardless of how it's mounted. So what if the stabilization system detects its own vibrations? How is that worse from detecting shaky hands or wind or a small earthquake?

    Resonance. Just turn it off when mounting on tripod.

    Some lenses have "tripod detection" that automatically detects if it's on a tripod and de-activates the image stabilization. Finding out which ones is the hard part though. Good to just turn it off every time, but I forget to pretty often without any ill effect that I've seen.

    It sounds like something may have been missed in the translation. From what I gathered, IS consumes power hence it should be OFF when using tripod, and should be OFF in Bulb mode so that IS doesn't ruin the image with trigger hold down.

    According to Canon manuals my 24-105L IS, 70-200L f4 IS, and 100L macro.

    The 100L macro also provide.

    Below is the answer from Nikon.

    Interesting! I was actually just wondering last night about use on a monopod and that last line answers my question! Thanks!

    Common thought is that VR shouldn't be used on a tripod because it can potentionally add vibration where otherwise there was none. It's highly unlikely to actually damage any of your gear, but it can negatively impact image quality, especially with long focal lengths.

    Obviously there is some middle ground here because if vibrations are being caused by environmental conditions (a strong wind), VR could probably be used to help counter that, but its a case by case thing.

    I've never heard of it doing permanent damage but I've seen the effect of it on from perhaps a different perspective.

    Video taken on a moving ship while the camera is on a tripod, pointed across the room will reveal movement like the camera is actually rolling back and forth. The sensors detect movement (from the ship) and are compensating. It's subtle but there.

    Additionally very loud sounds like a snare drum nearby will also make the image "jump". I would ONLY use IS when the camera is handheld.

    it doesn't make sense. the major brand IS (Canon, Nikon) is in lens, not in body. Olympus with the OM-D is the most major interchangeable camera maker to actually offer IBIS or in body IS. which is why I love them but anyway.

    how the hell would lens-based IS damage the camera like this warning says, i can't fathom. and when they say "camera's IS" again, they are only referring to a tiny bit of the market. the vast majority of IS is lens based.

    Is the idea that it will constantly move to compensate for its own created shaking, and cause the mechanism to overheat?

    I have shot at least 50 shots with IS On, using the 70-200L f4 IS and 5D MkII on a tripod, and both the lens and body still functioning perfectly.

    I find it hard to believe that the people who designed VR wouldn't even consider it a usage scenario for someone to turn their camera on and then set it down on the table or something, let alone put it on a tripod. I think the one thing about it saving battery by turning off VR makes sense and even the notion that maybe it adds a little vibration on its own could have some merit, but damaging itself just seems beyond what I would consider reasonable. Perhaps the little motors for the stabilization can wear down so turning off the VR whenever possible will help with longevity.

    I believe most if not all Sonys do in-body stabilization, and they offered it before Olympus ever did.

    that's true, Sony did do that before Oly, strangely so they did not in their NEX cameras which is the main reason i waited for the OM-D when i wanted to downsize.

    regardless Sony is still a small player in the dslr market, this warning is very general, which means it is speaking about the main market, which is still Canikon, who use in lens IS not IBIS.
