IBIS and OSS

[pilsburypie]

So, the first is the sensor stabilisation, the second is the lens.... If you have both, is your setup "double stabilized"?

 

Only asking as I'm torn between the A7s for it's super low light ability with no IBIS, so needs an OSS lens and the new nearly here A7rii with the IBIS..... if I pair this with an OSS lens will I end up with better stabilisation?

Member Yali gave the following nice answer to a similar question:

 

"An A7 with IBIS will correct for 5 axis of shake. A lens with OSS (Optical Image Stabilisation) will only correct for 2 axis (Even though it does those two axis better). So when you mount an OSS lens on an IBIS body the camera will actually recognise the OSS lens and revert to 3-axis stabilisation and let the lens do the other two. Which will give you even better stabilisation than only IBIS or only OSS."

 

I hope this helps!

Wow - What a clever system. Thanks for that answer, clear, concise and exactly what I was after. Bang on.

I just commented on the use of the 90mm macro in the lens thread with both OSS on and off along with the sensor IS. With the 90mm macro the combination works quite well. It appears that the OSS is much more relevant as the lenses get longer. I have been using the Olympus E-M1 for quite some time with the sensor IS and it has been outstanding. Olympus has had to delay the release of their 300mm "pro" lens to add OSS to the lens because the in body IS was not getting the job done on the longer lens. I will continue to shoot the 90mm macro on the A7 II with both systems engaged as that seems to yield the best results hand held.

Not tried it yet, but when using a long lens on

an A7M2, if it's an adapted lens [all my lenses

are Nikon MF] you tell the IBIS menu the FL of

the lens to match its behavior to the lens. I do

this as needed, but have not yet put a 300mm on

the camera [had the camera only 2 weeks, and I

seldom shoot long FL, so hasn't come up yet].

 

Never used the OM IBIS cameras, but do they have

such a menu for setting the FL ? Sony's menu goes

way beyond 300mm, which implies that it should be

capable. What I mean is that if the Sony IBIS can

be optimized for lenses [let us say] of only up

to 200mm, then there's no need to clutter the FL

menu with all those longer FLs. They could simply

warn you that for FLs beyond the max in the menu

one has SOME benefit of IBIS, but one also ought

to exercise additional care for handheld as the

FL in use increases further beyond the menu range.

 

OK, lotsa speculation and guessing here, but hey,

it's The Internet :-)

 

P.S. I guess one huge hint toward answering this

will be whether Sony puts OSS into ALL their FE

lenses that are longer than some threshold FL,

perhaps around 300 and up, despite the fact that

the IBIS menu IMPLIES that the IBIS on its own is

able to handle much longer FLs.

 

P.P.S. I can further imagine that even if Sony

"enforces" OSS concerning FE lenses above 200 or

300mm, at some reeeeally long FLs [maybe 800 ?]

perhaps they'd leave out the OSS cuz you'd be

waaaay beyond most users handheld expectations,

IOW, you're into tripod territory for sure, so no

reason to clutter the lens design with OSS.

 

P.P.P.S. [WATCH THIS SPOT !]

 

P.P.P.P.S .... Hey, just making fun of myself ;-)

I thought the IBIS was only 3-axis and only turned 5-axis with a Sony OSS lens.
