Klaus! Honestly, it was sheer coincidence that I referred to the miserable performance of the RF f/1.8 "macro". Look at the time stamps if you don't believe me!

I don't want to dwell on its shortcomings. I liked the first sample picture, of the lake! Probably, the need for close focusing and that wide an angle would have suggested a slower maximum aperture. I have the Olympus 30mm F/3.5 Macro for MFT. Even it struggles a bit.

I wouldn't really refer to the RF 35mm as a true macro lens. It has no floating system just to point to the obvious.
And it's a 35mm lens which is hardly ideal in this respect anyway.

What does that mean, "it has no floating system"? 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).

Hmmm quality aside the sample pictures of 70-200f2.8 are just like dpreview style, you seem to be only inspired by MFT...

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

No "Float" icon.

Well, I've pretty much a "standard" test location (Cockatoo Island in Sydney harbour) - so there's little variation between the reviews in this respect. It's just "efficient".

I tend to take MFT on vacation which is why you may spot something different there at times.

Ok, so this is no real macro lens (no "Float" icon):
https://www.cla.canon.com/cla/en/consumer/products/cameras/lenses/ef_100mm_f_2_8l_macro_is_usm

And this is no lens at all, let alone a real macro lens (no icons at all):
https://www.cla.canon.com/cla/en/consumer/products/cameras/lenses/ef_180mm_f_3_5l_macro_usm

And another not real macro lens? :
https://www.cla.canon.com/cla/en/consumer/products/cameras/lenses/ef_s_35mm_f_2_8_macro_is_stm

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"...
