Very nice! I think I'd have to be over the top picky to find fault. Your photos tell a much better story than photos of pine needles. Proving once again that the photographer is most important. The only thing more to wish for (just my taste) would be for the lens to be internally focusing like the 70-200. It would probably make the lens heavier and bigger, but I would be okay with that. Your shots have sold me. I'm sure the R version is just as good. Sometimes one must wonder if people commenting about lenses have ever actually used them. I think the answer is they have not, in many cases. A lot of regurgitation goes on.
Do you mean internally zooming? It already internally focuses. I think the main draw of this lens is that it offers a very wide zoom range and can be compressed down at 24mm for traveling.
So far, the new RF 24-105 is better than the EF versions in every way...so I'm delighted. I plan to use this lens for all my travel photography around the world, as well as much of my professional work like races and editorial images like the car photos I shared.
