You can't use the R7 with IBIS switched on and the lens IS switched off. IBIS wasn't a thing for Canon when the 10-18mm came out in 2014, so generally the EF-S and EF lens' IS wasn't designed to work in conjunction with IBIS. People have complained about this here, but I don't have first hand experience of those lenses on that body.But the EF-S 10-18mm *does* have IS…That's exactly what I was saying. Its IS wasn't designed to work in conjunction with IBIS though, and you can't set the R7 to have either system working without the other, so the lens's IS is potentially a disadvantage on the R7, though definitely an advantage with the R10 and the R50.EF IS lenses don't get full IBIS support, but they do get IBIS benefits, not sure where you got your info.  While RF lenses get more advanced coordinated IS/IBIS, IS and IBIS in EF lenses does work together.Canon EOS R7 - In-Body Image Stabilizer (IBIS) - Canon Central and North Africa (canon-cna.com)
