Canon RF 20-50mm f/4L IS USM PZ Specifications

[Del Paso]

I wish it went all the way to 70mm (like the Sony 20-70mm f/4 G) but compared to teh Sony: it is a power zoom, which is a plus, and it is optically stabilized, which is another plus. I'm in for one, I think.

All you have to do is wait for the RF 20-70.
Unlike the Sony, it could be an f/2,8, which would make more sense as a replacement for the current 24-70.

Will we need the latest R1/R5 II firmware for this new lens?

I guess, that R5II's Figaro firmware 1.3.0 already should support it.

No, I tried it yesterday with my original R6 without issues or warnings.
EOS RV cameras should allow further adjustments to zoom speeds though.
