Is a Canon RF 14-28mm f/2L USM on the way? [CR1]

Shooting at ISO 1600 and not 3200 is the point. Amongst others.
Thanks for the answer, instead of just attacking me for asking the question.

I'm trying to think though, even in candlelight I can shoot a 35/1.4 wide open 1/15th on 1600 film (and did so 1000s of times). At 14-15mm, you wouldn't even need IS to be on to obey the reciprocal rule.

At 3200, you'd be at 1/2 a candle.

With IS of say 2-4 stops, you'd be at 1/8th to 1/32nd of a candle.

I agree there must be somebody somewhere who would rather take a shot in 1/32nd candlelight at 1600 instead of 3200, but would you at least agree that this isn't going to be a common type of photography? If this is an actual drive for sales I'm happy to believe it. I just want to clarify that you're saying this is important enough that f/2 be offered, and indeed the reason perhaps most worth mentioning as it's the only one you mention?

What are the "amongst others?" Again happy to hear you out and learn something. To be clear I don't see the purpose of it, but I'm not saying there's no purpose. I'm just asking what the purpose is (besides the reason you've already kindly given).

What matters isn't that it is common for the average photographer or not. What matters is whether or not a large enough number of people would rather shoot at a faster shutter speed in the same amount of light at f/2 vs f/2.8 to make it a profitable product.

You want a defined purpose. For you, there may not be one in any case. But that is not the point. For somebody else there is a purpose and it doesn't have to be explained or justified to anyone... even for the sake of argument. It is very simple: Some people are willing to pay more for a larger aperture. Whether or not you or I think it is a good idea, smart, worth it, or anything else, is none of our business. Canon has identified a lens/focal length combination Canon believes will be profitable and have produced it. Is Canon right or wrong? We will see.

I am not the attacking type! :) Been there, done that. Realized it does not work. f2 with save you a stop of ISO. If that matters to you or not, you decide. For me, 1600 ISO gives a visibly better IQ. The other purpose would be a background blur.

Can shoot at one whole stop faster with 2 times of light gathering capability means a lot for F2 zoom vs F2.8 zoom

My mail clearly kicked off in bold with: what is the point?

I am not making a statement, I am asking a question.

So why do you say "Thankfully Canon isn't listening to you"? I'm simply asking what the purpose is. Why are you so aggressive to me?
Because your post reads like a nonsensical rant and your questions sound rhetorical? :unsure:

Given the choices between the RF 24-105L f/4, 24-70L f/2.8, and 28-70L f/2, I went with the f/2. Really sad I did every time I have to carry it a long distance and really glad I did every time I look at the images taken with it.

The RF 28-70L f/2 is like having several Otus primes in one lens: sacrificing f/1.4 but gaining autofocus. The rest of the f/2 trinity will likely be equally world-class. But those for whom the IQ, convenience over primes, and rendering do not outweigh the lack of IS and the extra size and weight, Canon has us covered there, too with f/2.8 and f/4 versions.

Maybe you just got caught up in the whirlwind of everyone else's naysaying, and you genuinely wanted to know. I say look at threads about and images taken with the 28-70 to better understand why someone would want the rumored 14-28 f/2.

^ To further add: don't think that means that I actually will buy the wide and tele f/2 zooms from the f/2 trinity. I'm pretty happy to sit on the 28-70 like a toadstool and position other lenses around it. I bought the RF 70-200 instead of waiting for the 70-135 f/2 because my need is for a small, light lens with more reach than 135mm for travel. I plan on getting the RF 15-35 f/2.8 for travel as well. Then I'll put my RF 50 f/1.2 squarely in the middle for my own oddball trinity. But I can see why the wide and tele f/2 lenses would be nice for some.

Just playing devils advocate here ...

Nowadays what difference does that make, iso 3,200 from basically every modern camera is more than usable for pretty much everything, f2 often doesn't give you the dof you need.

I can see a use for both f2 and f2.8 zooms but the size weight and cost of these f2 zooms makes even faster primes even more appealing.
Agreed! But iso 3200 on the EOS R doesn't look great at a pixel level.. I like to max out at iso 1000 if I can.. I find that to be very clean.

Are you talking RAW @ISO 3200 or OOC JPG?
At any rate. Anything up to ISO5800-ish should not be an issue. Not even at a pixel level.

Talking about RAW images with no noise reduction applied. I find even iso 1600 reduces sharpness and adding noise reduction on top makes things worse. For normal digital display sizes, 3200 is fine though.

Right. Could you please review the following page and see if Canon R RAW at iso3200 was substantially noisier than 5D4 for you? thank you.

Thanks for the link. I used to own a 5D IV and I would agree the noise between the two cameras is pretty much the same. Very happy to now have a couple of really nice f1.2 lenses to avoid ever having to go that high with the ISO
