OIS off when using 35mm adapters?

Just watching the video tuts on the cinevate website and Dennis says to always have OIS off when using the adapter. I have a brevis and use OIS fairly frequently, has anyone run into problems with having OIS on?
 
OIS should basically be off wheneve the camera is not being hand held, regardless of adapter use. If you're going run'gun with a properly framed Brevis, I'd turn it on actually. You just need to make sure you're aligned and zoomed in properly so the camera does not detect the edges of the GG.

Cheers,
Dennis.
 
Wait so, you're saying it can be used as long as its not picking up the edges? I was always led to believe this was a "always off" function for adapter use.

No, this doesn't work.

It isn't because the camera sees the edges of the frame. The vibration transfered from the adapter to the camera body freaks out the gyro sensors controlling the OIS.
 
I've never noticed anything funny in my footage and I'm pretty sure I use OIS most the time with the adaptor. I've only watched my stuff on a 40" screen so might do some test and watch check it out on my roommates projector.
 
I also heard if the OIS is on when paning with the tripod smoothly, it gives a slight kick-back at the end of the pan.
 
I shot my Lovefest entry with a Brevis on an HVX and we had (accidently) left the OIS on. The result in addition to the regular hand held look is really little micro movements I find very distracting during any scene where there isn't a lot of movement.

If you check out the Double Date and look at the phone call scene with the two girls you will see what I mean.
 
Best thing is to test first, and make sure all is OK as every camera/rig will behave differently, particularly at higher shutter speeds with the adapter. The classic question we get is that pans don't stop when they should as the OIS keeps wandering a bit and it looks like the imaging element frame is wandering. I only ever use OIS when the camera is being hand-held...it's always off for tripod work as it should be. We do use it with the adapter when doing hand-held shots with success...but again your mileage may vary :-)

Remember that overscan may not appear on the LCD depending on your camera, but if the GG edges are seen by the camera, OIS will be a problem.
 
I always have the OIS off when on sticks, however I always trun it on when going handheld while using the LEX. I found out to zoom in just a tad more in order to get rid off the edges that sometimes pop into frame. And I am always pleased with the footage.

When I first got my 35 adapter, I kept getting the exact problem Dennis discussed here. I couldn't figured out why until someone pointed out that I should turn off my OIS. It is working fine ever since. And yes, this is on a tripod that I experienced this problem.
