3) How wide is the 14mm? You may think that's a bit of an odd question, but according to the patent, the actual focal length was 14.8mm, so calling it 14mm is being a little generous.
Rounding 14.8mm to 14mm would, IMO, be unethical. However, it's important to note that specific lenses are not patented, optical formulae are, and also that most patents contain many such formulae so it may be the one you've seen that looks like a 15-35/4 is not the one on which this 14-35/4 lens is based. Nor is it a requirement that a lens be based on a patent.

Rear filter mount?!

I want a way to mount filters near the sensor - I know there are some? But its a new thing...

I hope it will cost under 1500€ ... :( news lenses are so heavily expensive. I have already the 16-35 4.0L IS.

The traditional advice for new users to choose between Nikon and Canon: try both, and pick whichever one has things turn in a way that feels right to you.
The good thing about Canon for me is that all the lenses Mount the right way but only the zoom lenses operate the wrong way.

I previously posted that I'd prefer a small 18-28 f/2.8 IS, and I'd still prefer that, but the small size and low weight of this f/4 could make me a believer.

Size and weight and front filters look amazing....but a few things before I'm ready to swap out my exceptional Sigma 14-24mm f/2.8:

1) Image quality - this thing will need to be outstanding.

2) Flare resistance.

3) How wide is the 14mm?
4) or 1.1) My only concern is vignetting, which affects several recent lenses.
If vignetting disappears at 15-16mm or stopping down to F/8.0, it's an issue only for the inevitable Youtube clickbait.

5) Price in USD and in Eur. We'll see soon.

With the RF 15-35 f/2.8 IS and the 14-35 f/4 IS, I wonder how Canon will slot in a 14mm prime. I hope Canon goes like sigma with a 14mm f/1.8 rather than like its overpriced EF 14mm f/2.8. And hopefully, it'll be designed for minimal coma.
One solution would be to introduce a 13mm prime (on a Friday)

It weighs 540 gm, 24-105 weighs 700 gm.
Indeed, but I was referring to size, which the 14-35, being about 7mm shorter, is pretty close. My image comparison is definitely not accurate, though both 24-105 and 14-35 would occupy about the same volume in a bag.

It's clear that ordering the first day (or hour, or minute) is the best way to assure that one get high-demand product in the first batch, usually the first day. Avoids months of waiting for hits like the R5, and the 100-500.

Besides checking in here and elsewhere occasionally, what's the best way to avoid missing out on the announcement of the release, and the oopening up of ordering by retailers? With the R5 there was a live announcement that was the starting gun (and might well have been open for orders prior), but other items might not have a pre-announced announcement time. Any good lists to be on? Frankly, BH ought to have such a thing to tell me the instant it's open for me to buy from them, or in advance.

are you saying the rf 24-70 f/2.8 vignettes more then the ef 24-70 f/2.8 ii? i thought the rf glass was at least as good as the ef.
Yeah, it does and not only that, the lens correction profiles in lightroom don't completely eliminate it. Great otherwise but it's a bit of a pain if you like shooting wide apertures.

One of the issues is that the amount of vignette depends on the focus distance, which I don't think LR handles. DPP4 does.

That's great until some poor dumb bastard thinks Canon is right about how to insert and lock lenses but wrong about zoom. Or vice versa. :D
This PDB knows Canon is right, but spent too many decades zooming the other way to quickly unlearn the reflex.

I wonder how much it will cost, but probably, seeing the way that L lenses are getting, no less than two grand. The 28-70 f2 deserves every euro that it costs and I love it, lets see this new one in IQ.

Never was with Nikon, but the zoom just seems backwards to me. But lenses follow righty-tighty lefty-loosey.

(Yes, that means I too am a PDB.)

When I drive the screw “in” (clockwise) I expect things to be closer. I’m begging anyone for a powerful explanation for the reverse I can use to reprogram my brain.

The numbers on top of the lens go to small to large left to right, just like the way you read left to right. Forget the screw analogy. Heck, forget thinking about rotation direction at all. Just tell your brain that left side of the barrel is small number and right side is large number. By turning the ring you are just moving across a page.
