Sony a7rii and long lenses?

Since the body has IS built in, would an older 300 2.8 or 400 canon non is lens be a good choice. No IS but body handles it and would cost substatially less. Anyone doing this with the a7ii for comparison?

Often the addition of IS is accompanied by an optical upgrade as well.

I am sure the addition of IS to a lens like the 300 or 400 5.6 will be great as we know they are very sharp lenses. But the same old problems of old lenses will appear, lack of parts for example.

I updated the firmware in my Metabones IV adapter and now have the benefit of in lens IS along with IBIS for Canon 300 F4. Even with teleconverters.

I'm looking forward to the A7RII and glad that it will do a better job at AF with the lenses via adapter.

I didn't think that stabilization would "add" so nicely as you have indicated... Unless the camera body can tell the lens exactly how to behave...

Thank you for the link. That was great info. I am getting excited for the a7rii.

In the instance when the lens has IS the camera relies on the lens to provide that axis of stabilization and it supplies the others.
That's why one has to set the OSS to manual and then input a focal length for the attached lens.

I'm not sure what happens when I turn IS off in the lens. I know I don't hear it working but I don't know if the camera then begins using all 5 axis for IBIS.
