A few lenses I would consider would be: RF 24 mm Tilt-Shift, RF 70-200 mm f2.8 Z internal zoom, RF 200-500 mm f4. Might pick up a 24 mm f1.4, but am still undecided.
We typically have similar taste in lenses, but I’m not so sure this time…though, mostly it’s because current lenses meet much of that.
I’m not sure what a TS-R 24mm would offer over the TS-E. I’d be interested in a 14mm TS, though. I like the compact size of the RF 70-200/2.8, enough that I’d actually prefer the 24-105/2.8 with an extending design.
For me, a 140-420/4 (100-300/2.8 + 1.4x) is close enough to a 200-500/4 for field sports and similar use cases, and while it’s not a small lens the 200-500/4 is likely to be about the size of a 600/4.
Many years ago, in deciding between the 35/1.4L and 24/1.4L II, I picked the former as my preferred focal length. I still mostly shot it at f/2 or narrower, so the 28-70/2 covers that need and many more.
Based on recent rumors, I’m not really seeing any lenses to tempt me. At least the yield on my gear fund is reasonably good these days.
