A 10x lens would be so tight that it would be useless most of the time, even for fusion. We either need an additional 70mm equivalent lens or a proper mechanical zoom lens before we can justify a good telephoto zoom.

I’d agree - given the choice between a 10x f/5 and a 5x f/2.8, I’m going with the fast lens every time.

Literally took picture of my cat seconds ago before reading this post at 10x because I didn’t want to stand up
