SL2 - Tripod & IBIS - on/off?

[hofo100]

When using a tripod and lenses with image stabilization, there is a common understanding to disable the stabilization in the lens when mounted on a tripod (this is also the recommendation in the SL-601 manual). Now, is there a change with IBIS in the SL2? Does it make a difference in this regard if stabilization takes place in the body or in the lens? The SL2 manual is silent on what to do when using a tripod. 

...and pls, no comments that with IBIS there is no need for a tripod;)

I would guess it doesn’t matter but do not know the correct answer. Assuming you leave the function enabled all the time ( which is the default setting) and the camera is stable , then IBIS is not going to be doing much so I can’t see that it matters. But would love to know the answer as well.

 

i will add that the feature is pretty remarkable. I always wondered why certain people always complained when this feature wasn’t included in a new camera. Now I know why...it’s priceless, especially for video.

My tests with the SL showed that OIS  on or off didn't matter, same result, that's the great thing about the SL it couldn't read the manual.  I would recommend testing despite whatever the manual says or answers from forum members that may have different tripods/techniques etc.

IBIS and OIS have been on permanently on my S1R for the last 8 months and it makes no difference whatsoever. I would be surprised if the SL2 is any different. I was specifically told by a Lumix Rep that leaving it on helps and it reduces micro-vibrations whilst on a tripod.

+1.

For those lusting for controlled testing, one can remotely trigger the SL2 with a large lens, say SL 90-280, mounted on tripod, using the mechanical and electronic shutter, the former with different shutter speeds. With and wo IBIS (plus OIS, if one prefers). A dozen or so exposures for each configuration should show systematic differences, if any. One can do this in a wind-free situation, and with some wind. I have not been shooting with the SL2 on tripod yet, but I may run some tests. For the sake of curiosity, if nothing else...

The S1R has a vibration meter that shows how much things are moving around.  Putting that on and seeing how good hand-holding technique differs from using a tripod, and using a tripod on a windy day would be a good start to adding a little real information to this discussion.  The SLs don't offer this feature  (unless someone can hack the firmware and bring it to the surface), but I would assume that any results from the S1R apply.

Thanks! Can you menu-guide me to the vibration meter; don't remember seeing this on the S1R...

The manual has a good index, but what do you call it?  "I.S Status scope, page 355"  Gear . Monitor page 3.

I have IBIS set to work when the shutter is half pressed, so when there is an image and the shutter is half-pressed I see a red dot dancing about inside two sizes of target circle.

To test vibration on a tripod, i would guess you first have to set IBIS to be always on.

Why would you switch ibis off when on a tripod? Y’all are discussing whether to but how did the idea emerge? 
after all, what’s the difference between a tripod and a steady hand (for short periods)?

You will find that as a manufacturer's recommendation sometimes.  The stabilization takes some sensor inputs and moves the chip to cancel those out.  If there is some noise in that signal, and the cameras is in fact lashed down on a solid tripod, then the stabilization will add motion, not remove it.  But on the S1R, which has a monitor, there is not much noise-motion, on a tripod with my finger on the shutter button, half-pressed.

[Exodies]

There must be a minimum shutter speed above which stabilisation can’t help. Is this also taken into consideration when using ibis?

[scott kirkpatrick]

Don't know, but I doubt it.  I imagine the stabilization routines live in a little world by themselves.  They get some inputs from the lens, and then do their thing.  Every extra connection is a chance to screw up.

Yes, there must be, and no, it probably isn’t.  IBIS above a certain shutter speed can actually hurt.  See Jim Kasson’s findings here: https://www.dpreview.com/forums/post/58089794

What cameras really need is i(ntelligent)IBIS. 😁
 

Edit - read Jim Kasson’s other posts in the linked thread above.  He thinks that IBIS is usually unnecessary at shutter speeds faster than 1/(5*FL).  This guy is a thorough tester.

...Which motivates me now to program one of the buttons on the SL2 to turn off IBIS when the shutter speed is indicated to be equal or greater than 1/(5*FL).

He also demonstrated that with a7II it is better to turn off IBIS when on tripod. But all those are recommendations are for a specific camera (and lens?) and may not translate to other cameras. IBIS technology has developed quite a bit since a7II was launched.

One could argue that it is better to turn off IBIS when using the camera on a tripod to save battery life but I have no idea if it makes a measurable difference.

I asked this exact question to the Leica technical rep on a photo walk for the SL2 on Tuesday and he said the ibis is to be turned off when camera is on a tripod. 

[darylgo]

Tripod use has many variables, including camera variables, technique, stability, weather conditions etc.  Hard, fast rules may apply but there's too many variables, testing one's own equipment is the only sure way to know.

Hallo,

I took my first 1/4000 sec. shot today, with IBIS.  It looked really sharp.
