p.1 #1 · Sony OSS and IBIS interaction?


I know OSS lenses have on off switches, the question is what to use OSS or IBIS?

Do you have to chose only one or can they both be active and supplementary in giving even more IS?

I am wondering this because in video you need as much IS as you can get.

Has anyone played around enough to answer this question?

Too get full stabilization (5 axis), both OSS and IBIS need to be on.

Hmmm . . . what am I missing here? When my 70-200 FE's mounted, the a7rii tells me Steady Shot is not available with that lens -- and glancing through the Sony online help guide tends to confirm that with OSS lenses, the lens control must be engaged rather than the camera's.

So, I, too, will be glad to hear from other users with more experience . . .

They work together, and it is rather well documented.

Here is one mention from Sony when the a7II was launched.

That didn't exactly explain it to me. Also, when using Canon lenses mounted via the Metabones IV EF to E mount adapter is Canon IS work with the Sony A7rII IBIS.

So many people have Canon glass for use on Sony

Well, ok, it's one thing to have a pre-release piece talk about the 7rii's functionality, but I cannot ignore the menu message I keep getting (nor the Sony online help) which says that with the 70-200 lens, stabilization is available through the lens -- only. Would love to hear otherwise -- with concrete steps explaining how to achieve it.

(and apologies if I'm hijacking the OP's question…)

Maybe clean the contacts or check your menu settings.

When I try mine, if it can't get enough light to operate in what it thinks is a good enough range, the steady shot badge flashes. If I turn the lens off, I get the steady shot off message on the screen.

If you use a native lens with OSS, you get 5 axis, if not, you can get 3.

Thanks for the attempt to clarify -- my question, at least. I find with the native lens in question, that when I engage the lens switch, my screen does indeed indicate "On" for Steady Shot. But when trying to enable just with the camera's menu settings, the "This lens doesn't …" pops up.

So, based on what you say, switching the lens to OSS ends up doing the maximum stabilization? If that's true, I guess with this particular lens, one couldn't opt for lens OR body stabilization; you get BOTH regardless?

Kind of academic for me, as I do mostly tripod shots, but having tried a hand-held pano with the 55mm earlier today, I was blown-away by how well it worked! The tripod may collect a few cobwebs!

Sony will (probably) fight against the Canon IBIS. Turn one off. If you shoot A mode, turn off the lens. Otherwise it will fight to keep you at 1/focal length.

No, you should be able to use either.....

Steady Shot on and OSS on = best 5 axis
Steady Shot on and OSS off = good 5 Axis (it's a lens with D encoding because it is a native e-mount)
Steady Shot off and OSS on = lens based (2 axis)

The picture about the IBIS and OSS inter-play at the following dpreview page might also be helpful:

I SHOULD just let this drop, as the issue will likely never affect my photography, but I'm so darned curious now, that I'll keep trying one, last time. Thanks for the responses, and both the illustration and commentary suggest that the two systems can be configured off/off, off/on, on/off, and on/on.

With the 70-200, I can toggle the lens OSS on and it registers as "SS ON" on my screen (giving on/on, I guess), but with the lens switch off, the menu will NOT allow me to turn camera-based SS on (a "not available"-type message appears)

I'm making a mountain out of molehill, but the question has become this afternoon's burr under the saddle!

I can't do that with the Sony 90 macro or the 16-35. They both have two options - on or off. With the 90 macro you turn it on or off on the lens, and cannot turn it on or off via the camera menu. With the 16-35, there is no switch on the lens and you can turn it on or off via the camera menu. In neither case do you have separate control over lens and body IS, you can only have it all on or all off.

I don't think the illustration says that you can individually control the body SS and lens OSS. It seems to me that for OSS lenses the camera will always us the lens OSS for two of the 5-axis and it is only for non-OSS lenses that it will use all 5-axis on the body. So I think just as you guys are experiencing, with OSS lenses you either have image stabilization completely turned off, or you have both OSS and body SS working together.

So, yeah... lenses without switches (24-70/4, 16-35, etc...) there isn't a way to disable OSS physically.

As for the chart from DPR, it isn't entirely accurate. For an A-Mount lens to have 5-axis IBIS, it has to be a D lens, meaning it has Distance encoding/ADI flash support. They can be determined by having 8 contact pins. Lenses before the D lenses (the vast majority of Minolta, Tamron, Sigma, Tokina, and all the rest) only have 5 pins. These 5 pins limit the IBIS to 3 axis.

Anyone have a view on Metabones, it seems to be working with SS since nobody I have read about mentions it.

If you switch FE OSS lenses that have a lens on off switch off I suppose the IBIS sees the lens as a lens with no IS and would provide SS just like it does for Legacy lenses.

I have some Canon EF lenses some have IS some don't somebody on the forum must be in the same boat and already have been using both types of lenses. Please add to this thread

Well, I replied above..... it's a bear to use well. You need to pick one or the other.

With Sony E-mount OSS lenses, stabilization is either on or off. If on it is split between lens and IBIS, with lens OSS handling pitch and yaw, and IBIS handling roll and X/Y translation. You cannot disable lens IS and enable IBIS separately.

With Canon IS lenses using Metabones IV on the A7RII, either lens *or* IBIS is used, but not together. You control which is used by the following switches:

Lens IS switch on: use only lens IS
Lens IS switch off: use only IBIS
Hold down Metabones IV button while turning off lens IS switch: both lens IS and IBIS are off

With metabones and Canon lenses you get the two axes (pitch and yaw) from the lens stabilization if it is turned on for the lens (and then you should shut off the camera stabilization. If you shut of the lens stabilization on the lens then ti is fine to turn on the IBIS, but you will only get three axes (pitch, yaw, and roll; no X and Y as that requires distance information that isn't supplied). In most cases because the lens can do pitch and yaw a bit better than the camera (that is why Sony let's the camera take care of these in its system) you are better off using lens stabilization and shutting off camera stabilization. By the way, roll mostly compensates for turning the camera as you press the shutter (or movement like that so be extra careful to not turn the camera that way when it is shut off. Bottom line the camera and lens systems cannot work together for Canon lenses and you are better off just using the lens IS and shutting off IBIS.
