I use this superb lens on the R5 and the results are truly impressive.
The 5x magnification is insanely detailed straight out of the camera, but everything has to be rock steady as the slightest vibration will ruin the shot.
For example if you have a timber floor, stand still when you take the shot because if you shift your weight and the flooring deflects slightly, it will show up in the image.
I use mine on a Manfrotto Sliding Rail for stability.
You need good lighting too as to achieve 5x magnification the subject can only be 41mm from the lens.
For 1x macro the subject distance is 101mm from the lens, so it is a different style of getting your shot.
The results are well worth the extra effort though.
