In my last article, Canon R5 Mk ii Drops Pixel Shift High Res. Is Canon Missing the AI Big Picture? I showed how IBIS High Resolution was useful in improving resolution and reducing moiré/aliasing. Having received my R5 mk. ii (R5m2), I set up a simple resolution and moiré test to compare the R5m2 with its "AI" In-Camera Upscaling to the original R5 with IBIS High Res (IBIS HR).
