That would be great if true! Precapture would be an awesome feature to add, as well as the others mentioned.
I’m also interested in the RF 100-500. I currently use the EF 100-400 II adapted to my R5, which I love, and also use the Sigma 150-600 C if I think I’ll need the extra reach. The RF 100-500 would replace both.
The f/7.1 aperture on the RF 100-500 doesn’t bother me since I typically use the Sigma 150-600 C at f/7.1 or f/8, I find my copy is sharper stopped down from f/6.3.
That said, I’m content with my current lenses so not sure I can justify the cost of upgrading to the RF 100-500. I would love if Canon came out with something similar to the 500 PF as far as budget, performance, and light weight are concerned!
