I can't find my manual but wondering if it matters if IS is on while on a tripod. I know the older versions of IS has to be off.

I think it should be tripod sensing.

But if in doubt and you know your using it on a tripod then I'd turn it off.

That is my plan for sure

IS position 1 is for off-tripod use, and IS position 2 is for on-tripod use, I believe.

For faster and accurate auto focus turn IS off when lens on a tripod.

IS is always turned off with my 70-200 f4L IS on a tripod/support...not sure about the f2.8 II

Here's what the manual shows about the two IS settings. Further in the manual, it states "When you use a tripod, the Image Stabilizer should be turned off to save battery power."

Traditionally with Canon, Mode 1 is used when hand holding steady, and Mode 2 is used when panning (horizontal motion). I do not always turn IS off when shooting my 70-200/2.8L II on a tripod. Being as the purpose of image stabilization is to reduce the effect of vibration, there are other techniques to reduce vibration if you turn IS OFF

I hang a sand bag from the hook under my tripod. This helps damp movement.

In "Proper Long Lens Technique", wildlife photographer Moose Peterson advises:

"First and foremost -you must rest your hand on the lens barrel above the
tripod head! (you can also put your hand on the bottom of the lens barrel if you're
pointing the lens down) You rest your hand on the lens just like you'd rest it in your
lap. Vibrations are what causes images to be out of focus, vibrations that normally
start at the camera. These vibrations travel as a wave to the front element and if
they are not stopped, they travel back through the lens to the film plane, causing
images to be out of focus. The simple resting of a hand on the lens barrel stops this
wave before it reaches the front. No, a bean bag resting in the place of the hand is
not a good idea for many reasons.

Second - use an eyecup and press you eye against it! This again is another way
to minimize or eliminate any vibration that might start with the taking of the
photograph. If you can't remember to press against the eyecup like I did in the
beginning, put a sticky note on the back of the camera to remind you.

Third - roll you finger when firing! Too many photographers poke at their shutter
release to fire the camera, causing all sorts of unwanted movement. You want to
rest your finger on the shutter release at all times and then slightly roll it unto the
shutter release to actually fire the camera. This takes practice, but makes a big
difference!"

FYI from CPN: http://cpn.canon-europe.com/content/education/infobank/lenses/image_stabilisation.do

Using IS with a tripod

When using certain early models of IS lenses with a tripod it was necessary to turn off the IS function. This is because of a phenomenon known as ‘Shake Return’. Shake Return occurs when the IS system tries to correct vibrations to which the system itself contributes. When the IS lens sits on a tripod, the IS detection gyros pick up any tiny vibrations or movement; these might be caused by the tripod being knocked, or the photographer adjusting a camera setting.

The IS system then swings into action to correct that movement. The movement of the IS lens group causes its own minute vibration, which is in turn detected by the movement sensor, which triggers another correction. This ‘feedback loop’ can continue endlessly, resulting in the addition of unwanted blur to images that would be sharper if the IS function was switched off.

Special mode

Canon addressed the ‘feedback loop’ in later model IS lenses by introducing an algorithm to the IS detection system to automatically recognise when the lens is mounted to a tripod. When these lenses are mounted on a tripod and the shutter button is pressed halfway, the IS system kicks in and the image in the viewfinder can be seen to go through a very slow vertical shift for about one second.

If the shutter button remains depressed halfway the IS system detects the lack of motion and automatically switches into a special mode. In this mode IS detects and corrects for mirror slap and shutter movement at slow speeds, but not for ‘normal’ lens shake. There is no advantage to be gained in turning off the IS function or locking the mirror prior to exposure.

The early model lenses which do not have this automatic function and which should have IS turned off (ie lock the IS correction lens group in place)

Image stabilisation is effective with movement from 0.5Hz to 20Hz (1Hz is one movement cycle per second). This will cope not only with situations from simple camera shake (0.5Hz to 3Hz), but also the engine vibrations encountered when shooting from a moving vehicle or helicopter (10Hz to 20Hz).

I don't know the date code off the top of my head, but my 300 2.8 IS v1 isn't on the list, nor is my 70-200 2.8 IS. Do I assume they are the "older" versions and it should be turned off?

I recall hearing this years ago before the v2 models were out so I assume it really depends on the date code.

Can't make out whether v.2 was after 2001 or 2004...

I can tell you my 70-200/2.8L IS Mark I (circa 2007) had infrequent problem with IS in mode 1 when on a tripod. So, I did occasionally turn IS OFF on that lens when tripod mounted. The same lens Mark II works great on a tripod in IS mode 1. When on a Gimbal mount to follow horizontal movement, I use mode 2. Handheld mode 1 is best.

A monopod isn't really mentioned, but vertical movement should be minimal. It should be close to panning, but has anyone tested it on older lenses on mode 1 and 2?

It depends.

The EF 70-200 MKII does feature tripod detection mode, so it does operate slightly differently when lens is on tripod. However the system still has residual drift. That means if the shutter speed is about 1/2 sec or slower you will start to get some blur from image drift.

If you have a cheap tripod or shooting in windy conditions or on unstable ground in general IS helps as long as you are not doing a long exposure. Otherwise turn off to be on the safe side.

The tripod detection works in both mode 1 and mode 2. Mode 2 is panning (either handheld, monopod or on gimball head)
