Let's face it, not all of us can afford the Canon L series RF lenses.
This seems like a good price for a "budget" Canon RF zoom lens with IS, lighter and cheaper, would go well with the RP.
P.S. Their web site stated PREORDER WITH $500 DEPOSIT.
According to the Canon web site, this is F4-7.1.
Ideal kit lens for your EOS R System camera
This small and lightweight standard zoom lens with 24 to 105mm focal length is perfect for shooting a wide variety of scenes. High-speed autofocus and Image Stabilisation for split-second photo ops along with never-fail, convenient functions for capturing precious memories makes this lens a perfect addition to your kit.
Equipped with an optical image stabiliser
The CIPA standard 5-stop IS effects reduce camera shake and allows you to shoot sharp images even with hand-held shooting.
A used Sigma 24-70mm 2.8 might work better.
