The RF 70-200 f/4, to me, would be pointless for wildlife. It isn't as fast as the RF 70-200 f/2.8 although it is lighter and more compact. The RF 70-200 f/4 cannot be used with the RF extenders. <https://www.the-digital-picture.com...Lens-at-200mm-With-the-EF-EOS-R-Mount-Adapter> The focal length is too short in most cases for capturing distant animals. It could be used for large mammals in good light if you were very close but that would make it a very specialized purchase. I once sold my EF 100-400 first series lens and picked up the EF 70-200 f/2.8. I quickly discovered it had all the disadvantages of the EF 100-400 such as large size and more weight and none of the advantages of having a longer focal length. Both of the RF 70-200 lenses seem to be more sports oriented with the faster lens more usable indoors. I'm sure others will add their opinions on this subject but I've found that I always want more focal length for wildlife and the compromises always come in the form of size, weight, and cost. At this point, the RF 100-500 is ideal for me but I also own the RF 800 f/11, RF 100-400, and EF 500 f/4 II. Even with those options, the RF 100-500 is on the camera body 99% of the time. The RF 100-500 is big, heavy, and expensive, so, as I wrote previously, the RF 100-400 is, to me, the best compromise as a starting lens.
