I think RF lenses are exactly what all this is worth. I do not know why. there is some magic in these L-s, the picture from them looks just magical, even simple plots look interesting. with other manufacturers, this effect is much more difficult to obtain, I have no idea why. you can compare sharpness, distortion and other nonsense as much as you like, but with L the picture is very cool, it is obvious even to a simple peasant that this was shot on something very cool. It is interesting that when zooming, the front part of the lens moves forward and the back part moves back, I have not seen this before.
