- Northlight has uncovered a USPTO patent showcasing some telephoto zoom lenses for the RF mount. These lens designs appear to be fairly simple and might suggest they're not L zooms.
The Canon EOS R system will obviously need some less expensive glass, and announcing a non-L RF 70-300 alongside an entry-level EOS R system camera would make a lot of sense.
Optical formulas included in this patent:
- RF 70-300mm f/4-5.6
- RF 100-400mm f/4-5.6
- RF 50-240mm f/4-5.6
I'd wager on the RF 70-300mm f/4-5.6 being a non-L telephoto zoom that will hit the market for the RF mount. I think Canon would keep the RF 100-400mm for an L zoom down the road.
M.ZUIKO DIGITAL ED 150-400mm F4.5 TC1.25x IS PRO with a built in 1.25xTC and an external 2xTC, available next year.
Edit - oops I meant to put the Olympus post in the Olympus thread. I'll repost there. Apologies.
Don't forget the original EF 50-200 f/3.5-4.5 lens was a full-frame lens.
Yes. An RF 50-240 lens could be a good consumer travel lens for a lower cost R body. Might even be sold as a kit lens option.
I would like to see Canon keep IQ very good on all RF as well as EF and M lenses. Like the did with the FD series lenses which for the most part were very good even if not L lenses.
Then save L for rugged construction and weather sealing for heavy pro abuse.
This would be a huge step in the right direction for Canon as all their lenses would be great optically just the mechanics, build and sealing will be less robust to save money.
I don't think Canon have released a truly BAD lens regardless of target market for a long time. Their cheapest EF lens, the 50mm f/1.8 STM is a superb optical performer for example.
