Here is the Canon RF 70-200mm f/4L IS USM

AlP · Oct 31, 2020

And here (copied from the lenses Forum) two size comparisons, one with the 24-105 f/4 and the other with the 24-70 f/2.8:

This will be a fantastic hiking or trekking lens! Curious about the price though...

Is it just a cheaper (and maybe lighter) version of Canon RF 70-200mm f/2.8 L IS USM ?
Which one is supposed to produce better images: f/2.8 lens set on f/4 or native f/4 one?

Image quality will likely be similar, based on the EF 70-200 lenses. It's the same choice as always between f/2.8 and f/4 zooms...a larger, more expensive lens with one stop larger aperture, or a smaller, less expensive lens with a slower aperture. Take your pick.

Waiting for more details esp close focus capabilities. That is one seriously small lens.

Woha this is sexy, I have the RF 70-200 2.8 but if image quality is good enough and price very low, I could consider to switch to this one to save money for another one good lens! I have to analyze the shoots I did under f4

Since I never had L series lenses less than f/2.8 ("Cheap people always pay twice" personal rule), I wonder which one is supposed to be sharper: an f/2.8 at f/4 or a native f/4.

Probably it will be the "little sibling" like the EF 70-200 F4 L. That old EF lens has great image quality. All RF lenses are very sharp, so probably this new one will be great too in all aspects. The main decision should be other factors like budget and use case.

Edit: I should have read the other thread before wasting space here

PBD did a better job already at comparing it to the RF 70-200 mm 2.8:

Canon to announce the RF 50mm f/1.8 STM and RF 70-200mm f/4L IS USM soon

The long-rumored Canon RF 50mm f/1.8 STM and Canon RF 70-200mm f/4L IS USM will likely be announced sometime in the next couple of weeks. These lenses have been delayed a couple of times already this year I have been told. As noted by Nokishita today, the lens hoods for each lens have been...

I wouldn't expect to save a lot of money by selling an f/2.8 and buying an f/4, considering that you'd sell at lower price and would pay taxes on the new one...

I guess you never took a hike with you F2.8 collection. The EF F4 L lenses were built with the same quality but half price and half weigth. I would not expect this to be any different.

Yes but not now, next year.

I have the 2.8 version, non IS. Great lens, but bulky and heavy (I think something like 3.2 lbs.) so very seldom carry far from the car in the field. This f4 lens would suit me fine, if I were able to afford a mirrorless body in the first place.

You are absolutely right about hiking: I never walk too far from my car.

I am just wondering how much this stop might save money and/or weight and whether it's worth it from image quality perspective. We'll see.

A f/4 70-200 would be a great lens to get into the Canon R but it is disappointing that'll mean no TC support. I don't know about a 2.8 vs 4.0 now, the new RF 2.8 is quite light so I canny imagine people owning both a f/4.0 and f/2.8 like I know a few did on EF (The f/4.0 being the preferred 'outside' lens).

The AF is supposed to still be working at f/8, no ? If it is f/5.6, then you might use a 1.4x one...

Well, not a Canon one at least. Physically, TCs don't fit on the RF 70-200 2.8 if they portrude at all into the lens. And I don't see why this would be different for this cheaper, more compact one.

Indeed, it is very disappointing (I've just read an article about that: I'm still using EF mount body so I don't have this problem yet).

Presumably they decided the size and weight reduction was more important than the ability to mount a TC.

I'm excited about this lens.

When I bought my EOS R I also bought the RF28-70mm f/2, a simply gorgeous lens (if a bit heavy). I like the idea of the RF 70-200mm f/2.8, it seems like the natural complement to the 28-70. But I just can't justify spending $2600 (or more) for every lens. I'm thinking that with the IS and the ISO capabilities of the EOS R this lens will suit my needs...assuming it sells for about $1000 less than the f/2.8.
