I am pretty sure the 35mm f1.8 does have a floating system (elements do change the distance to eachother at different focus distances).. It is my Micro-Nikkor AUTO 55mm f3.5 1:2 macro which has no floating system (all elements move as one block).

Canon mentions this for their other macro lenses but not for the RF 35.

No "Float" icon.

And this is no lens at all, let alone a real macro lens (no icons at all):

And another not real macro lens? :

Disregarding the silliness of "Float" icons.... This image does show the floating lens focussing of the Canon RF 35mm f1.8 IS STM Macro?:

And real macro lenses used to not have floating elements anyway (like my old Micro-Nikkor 55mm f3.5) float or no float is not a measure of whether a lens can be called "macro"...
