Turn off IS

[round]

Read it from other forums that one should turn off the IS while the lens is mounted on tripod.

Is that true?

With older generation IS, yes. With newer generation IS like the 70-200 F2.8 IS you don't have to, but it might save you a little bit of battery life.

It's even more complex than that.. but it depends on the lens.

Some 2nd gen Primes even have an IS mode that is designed to work when the long telephoto is mounted to a tripod.. the IS is then used to counteract the effects of mirror slap and camera vibration caused during shutter release.. even on a tripod...

So .. What lens?

I have a 75-300mm IS USM, the oldest of the IS lenses I think it's as gen1 as you can get.
Mine does work on a tripod from time to time, and it works great if it's windy on the tripod outdoors.

If you have an IS lens play with it, it doesn't take much to figure it out.

Mine is a 28-135 IS USM, bought this year. How about this lens?

It's one of the earlier IS lens, gen 1 or 2. It likely will have a tripod warning but I have read of those using it with good results in the wind on tripods. I have a cheap tripod that mine does a great job on, way lower shutters then if I hand hold and they come out crisp.

Give it a try it won't hurt the lens and if it goes crazy you will know it right away.

Mine came with a manual explaining it should be turned off while on a tripod and what the results may be if you didn't. Of course there are always exceptions to every rule. My guess is if you are waving your tripod above your head you should probably leave the IS on:).

I operate under the assumption the manufacturer of these products knows stuff I don't, so I normally consult the manuals -- at least as a starting point.

28-135mm Is gen one.. it is in fact the first IS lens as I understand it. Unless your tripod is no good (ie it moves a lot :lol: ) you should turn off IS on a tripod.

On a monopod IS can (and should) be left on.

The 75-300mm IS was the first lens with image stabilization.
