Patent: Canon RF 70-400mm f/4.5-5.6L IS USM and more

[Optics Patent]

I got a 24-240 with my RP that I never use and might well trade for a 24-105 f4. I’m doubtful there is a non L RF version of the 24-105. And with the 200g weight difference will first test the f2.8 and may end up like everyone else and preferring it.

If I recall correctly there's 24-105 L RF lens and a non-L one too.

Given how much actual distortion the 24-240 has, if I had a 24-105 L I'd be inclined to keep it.

There is no non-L version of the RF 24-105 (yet).

I have an EOS R with the 24-105L. The IQ issues prevent the 24-240 from being interesting for me. Both my EF 200mm f/2.8L II and my EF 100-400mm f/4.5-5.6L IS II provided good IQ, but I felt that the 100-400 had some focusing issues when using a 1.4 III extender. In any case, I have sold them both and I will be purchasing the RF 70-200 2.8 soon. If this RF 70-400 becomes available it is very likely to be added to my wish list.

Come to think of it, the non L lens I was thinking bout was an EF lens. I've seen it offered as part of a kit with the R and RP, so now I see what looks like a killer price, I have to check carefully that it's the RF 24-105L I am looking at.
