IBIS manual focal length settings for Sony A7R2 + S2 with Anamorphot

[Dick Sweeney]

What is the consensus - when manually setting the focal length - plus using the cropped mode in both Super 35 and the slomo - plus obviously the added ana lens. Ive been kind of doubling the lengths so far - in a general kind of way. I'm presuming that the IBIS takes on board the actually length as an approximation and counters the tilt and shake by applying the opposite on the chip plane. Sometimes my stuff looks stabilised and others shaky.

It would be to here

What length added in to say for a 50mm Plus Ana ?

And then say the same set up but then add in the S35 crop mode ?

And then same again without the S35 - but the Slo Mo 120 FPS crop on the A7S2.....

Or just stick on some sticks !
