Hi all, I have my new EOS R7 now. Ibis image stabilizer (not digital) is always on or there is an option to switch Ibis off?

R7 and IBIS image stabilizer
- Thread starter Frank EOS80D

My understanding is that the R7 behaves the same as the R5/6. The IBIS is always on if an IS lens is fitted. In other words, lens IS and IBIS work together. If you turn the lens IS off, the IBIS stays on (turning it off is not available). You can only turn the IBIS off if a non-IS lens is fitted. This is the way Canon have designed it, though it does seem counter-intuitive.

I thought turning the lens switch off disabled both IBIS and IS. An easy test you can do.
There is no way to disable IBIS and keep IS enabled.
Yes with non IS lens a menu appears that gives you and option to disable IBIS.

No, that's wrong. With an IS lens, optical IS and IBIS are both on or both off, controlled by the switch on the lens.

Yes, via the camera menu (don't have the exact menu option to hand but I remember it was easy to find).
The only real problem is that we need options for lens only or IBIS only for IS lenses, but they are permanently locked together, both on or both off.

Zeee is right. If you have an IS lens fitted, the switch on the lens controls both ILIS and IBIS at the same time. You don't have the option to use only IBIS (though why you would want to, I don't know). It's either both or neither. With a non-IS lens fitted, you get a menu option to turn IBIS on or off, and another to have it work only when you take the shot, or all the time. I think this is equivalent to mode 3 in IS lenses that have three modes. What might be confusing drsnoopy is the fact that, when you have an IS lens fitted, you don't get a menu option to turn IBIS on or off (you only have the digital video stabilization option). So it might look as if you can't turn IBIS off. But actually, you can't turn it on (without also turning IS on on the lens).
Apologies for my error. I wrote it in haste while travelling, and mixed it up. Lens IS and IBIS are linked, and controlled by the lens switch. If a non-IS lens is fitted, the default is IBIS turned on, but the menu item to turn it off is now available. In general you would want it on with a non-IS lens.

NP. This is why forums exist. For more general info if you do shut the lens IS button off the IS and IBIS are still energized, they just don't stabilize. It's the new IS tech that started with M lenses. The new tech uses magnets and the old EF was with springs I think? Sometimes you read about people mentioning they hear a rattle when the camera is powered down. That's more than likely the IBIS not energized and floating around.
On another note I sure wish Canon allowed is to shut IBIS off but use IS. I'd like to see how that performs with faster moving erratic subjects.

Please note that there is a menu/button option to turn on Movie IS. If you are shooting stills, LEAVE IT OFF. Turned on, it will cripple AF and degrade IQ. See page 308 of the manual.

Just to clarify
On the R7, Red Menu 8, (page 291of the manual ) there is an option under IS mode, that shows the movie camera symbol and Digital IS - which can be turned on or off. I am assuming that this is what you are referencing.
Just to note, with an IS lens, the IS Mode only shows the above option, but with a non is lens, it shows a number of other options such as Still Photo IS etc.
Was this what you were referring to?
Thanks

Basically, yes. But let me call your attention to Page 398 of the manual. My brief experience shooting BIFs with Movie IS activated corroborated the highlighted note. And yes, with the RF 100–400mm lens attached, both camera and lens stabilization are activated or deactivated by the lens IS switch.
I'm a bit surprised with your experience. Anyone else seeing this effect while shooting stills?
The caution in the manual is under the "movie recording" section
https://cam.start.canon/en/C005/manual/html/UG-04_Shooting-2_0130.html#Shooting-2_0130_2
The corresponding IS section under "still photo shooting" section doesn't have any such warning
https://cam.start.canon/en/C005/manual/html/UG-04_Shooting-1_0370.html
I'm not disputing your observation, just trying to see whether it's something specific to your shooting conditions or more commonly observed. There is no reason movie digital IS should do anything in still shooting otherwise we won't get the full sensor output

My guess is that Canon is talking about motion blur, you'll get streaks in the direction of the jerk, which doesn't always line up with the direction is the subject is travelling. The digital IS will stabilize the picture, but it can't get rid of the motion blur.
My point is that the digital IS should only be relevant when shooting movies, not in stills mode
We should have the option to choose when shooting still to turn IBIS off.
That we have, unless you mean independent of lens IS which we don't. But that's a separate topic. Above, if I understood correctly was about Movie digital IS which works by cropping the frame and should only be relevant to movie mode
Independent but you are correct. Separate topic.

I agree that movie digital I S should only be relevant when shooting movies, not stills. But I am not certain that that is the case. There is nothing in the manual that states that directly. And it is certainly possible to turn movie I S on or off when shooting in any stills mode. So my thinking is, when unsure, turn it off. Since it is obvious that movie, IS operates in a way different from, and perhaps more complicated than, IS mode for stills, I concluded, perhaps erroneously, that it’s net benefit for shooting stills would most likely be zero or negative.
On the other hand, I stumbled on this theory while trying to track down an elusive problem I encountered when shooting single frame, macro or near macro stills. The camera would focus on my subject, and then, after a few seconds, the focus would go soft, and then gradually return to fully sharp. (The focus drifting was readily apparent in the VF. ) This behavior would often repeat itself. An early test convinced me that it might be due to movie IS, but subsequent testing has failed to corroborate this. Originally I was shooting with the following settings:
One point or narrow area focus.
One shot focus.
Single frame drive.
I tested again today and I can confirm that this focus searching takes place with or without movie IS activated. Surprisingly, the focus drift seem to be associated with One Shot focus. When I switch to Servo, focus seems to be razor, sharp and rock solid. Since I was shooting handheld, I am now assuming that the focus drift was due to micro movements of the camera itself, which would be corrected in servo, but not in one shot. Focus. More testing to follow. In any case, I am still leaving movie I S off for all still shooting, thanks to the language in the manual
