Sure. The diffuser is small and light. It cost about $8. The diffuser simply slides on over the lens, and elastic around the opening for the lens holds it in place.

I was using a smallish flash, the Canon 430 EX. Seemed better to use manual rather than ETTL setting for the flash. Most shots were about 1/4 power.

I was using the R5, so there was IBIS. The lens was the EF 100 mm f/2.8 macro without IS.
