Hi folks. I've got a GH5 on preorder, and would like to pair it with a Nikon speedbooster and Sigma 18-35.
As I understand it, the Nikon speedbooster is non-electronic so the camera won't automatically adjust the IBIS focal length setting (whereas the Canon EF version may do so?).
So my question is, does anyone have firsthand experience with how the IBIS on a G85 or GX85 works with a Nikon mount Sigma 18-35 lens? If you set the IBIS halfway, say at 25mm, how well does it stabilize? I'd rather not shell out for a Canon EF speedbooster since I have no other Canon EF lenses, but if it works much better with IBIS on the GH5 I may have to do so.
Thoughts?
