A few discussions on other sites have raised the subject of when to turn it off!

Bit of a crusty old geezer with some in built shake !

I have mine on all of the time !

Even on a tripod I can not recall a shot where I was completly still !

Definitely not still on a monopod !

Even resting on a soft object or a hard object the same !

Some people turn it off aver 1/ 500th of a second.

What is the cocensus of others ?

Thanks,

JD

John I find its great for Macro or as you say slow shutter speeds, if its action / flight shots I'm after it serves little purpose as your panning and it will slow down the cameras ability to focus quickly

I turn mine OFF when the lens is supported well (the non tripod sensing IS) and for flight, panning shots.

Ive been trying a new technique (at least for me), supporting the lens on a ball head, with the tripod foot at 90 degrees to the righ/left (so not pointing up).

Leave the locking screws loose and the lens collar , so you can move the lens around without the weight of the lens/body combo on your arms.

If you suddenly get a shot where a vertical format shots going to be good, just rotate the lens, and because everything is loose the image stabalization works.

Ive been shooting "One Shot" with "Al Servo" switched "Off", as once youve attained focus on the birds eyes, you can recompose the image without the focus changing if you want to.

This is ideal for birds photographed from a hide.

G,day John,

On the 300mm f/2.8, I leave it on all the time. Tripod or not. I think the issue is more about the type of Stabilisation of the lens manufacturer. I had a Sigma 150-500 that was definitely better turned off on tripod.
I've never seen a significant difference in shots with any of the stabilised lenses I use above 1/250th On or Off. So in the end, I've taken the old bloke's way, and left it on.

On my 70-200 VR, it can occasionally cause a double image in the range 1/80th to 1/160th (or there abouts), I've always put that down to the frequency of the VR system, and just be extra careful at those shutter speeds.

Like Steven, I use a Markins Q20 ball, and it doesn't need to be "Locked", it has a lovely damping system that allows me to swing it quite easily and its stays in position.

"One Shot" is pretty much my weapon of choice too.
Always ON as it is very dary in the rain forests where I do my shootings. I tipycally work with very slow shutter speeds (1/25-1/30-1/50) so IS is a neccesity even when using a sturdy tripod and excellent lens-stabilizing technique! :)

Ive recently acquired the Canon EF 400mm f/5.6 so image stabilisations no longer an option.

I chanced upon this video on you tube by Moose Peterson about using long lenses..

I tried the technique yesterday though using the lens with 1.4x TC, side mounted on a ball head and it works, and for people with long stabilised lenses an added bonus.

Theres plenty of cheap copies of Gimbal / Wimberley heads available on amazon / ebay for under £100.00
