So far as I see Canon has no lens hoods for the RF 2/85 and 1.8/50 lenses in stock.
As I bought these lenses I fitted two screw mount hoods. They do there job but are not very handy.
Which lens hoods fit RF 2/85 and 1.8/50 lenses? Some dealer say the EF 1.8/50 hood fits the RF 1.8/50, too.
I found some 3rd party hoods for the RF 2/85 on ebay but I'm not convinced that they really fit this lens.
The info is available on the product pages for these lenses under the Supplies & Accessories section.
For the RF 85mm f/2, you'd want Lens Hood ET-77. See This Link.
For the RF 50mm f/1.8, you'd want Lens Hood ES-65B. See This Link.
Meanwhile I got the ES-65B, but this hood is far to big for the RF 50mm f/1.8. It is a very good transport security but not handy. It is longer as the lens and it is a pain in the ass to reverse the hood. It occupies also to much space in the bag.
My screw-on hood is much more handy.
I agree whith you. I have 2 JCC hood for RF lenses - the brand name may be different in other contries. They fit and work very well and have a press button.
But a lot other 3rd party hood on ebay are junk. My wife bought two for her EF-S lenses, one works since 2 years, the other one jammed after some months and is useless after 15 months.
