Ok so, the two lenses i'm thinking of are the telephotos. I own the 50-230ii, which is rated at 3.5 stops, and I've always considered a swap to the 55-200, which is rated at 4.5 stops.

However when I took a look at the X-H1 chart (which I included below), it says that with the X-H1 added together, these lenses only get 3-stops and 4-stops respectively.

I know that when added together, the IBIS takes over 3-axis while the lens deals with the other 2-axis (pitch and yaw).

So I'm confused as to why adding IBIS, which takes a 3-axis lens to 5-axis in total, ends up losing half a stop in stabilisation... wouldn't it then be better just to turn IBIS off for these lenses? Or shoot on an XT-2 instead?

Seems like there's something odd there, so I thought I'd ask those who might have experience with it!

Hi, I think it has to do with the smaller circle of confusion found on zooms. I've seen discussions which describe some lenses like the XF 10-24 as having smaller circles of confusion,. Hence, I imagine that the sensor has a smaller area to move about and not move outside the circle of confusion?

Hey, I actually take photos too!
