I use a Canon 24-70L as my standard lens, but in truth my natural eye tends towards 70mm rather than wider. Only rarely do I use my 16-35.

For me it is 35mm. I have been on a couple of trips / holidays lately where I wasn't shooting a paid job, and the Sigma 35mm f/1.4 basically moved in with the camera body and stayed there.
2 x 5DIII and various Canon and Sigma lenses + a small Fuji X lineup of stuff.

I would say it varies from either my 21mm or 35mm. Depending on how I am seeing things on that particular outing. For most applications I can use my 35 without any problems and can compose it very easily. The 21, I find a nice complement to 35, where I can "see" the end result without having to look through the viewfinder.

For me, 70mm on a 70-200 2.8L IS atached to a 5D MkIII, for a simple reason, with both eyes opened, one on the viewfinder, the other naked, gives me a perfect stereoscopic view like I have with both eyes naked. Only thing is that the eye on the viewfinder "gets" a dark framing. Can I see less of the world arround me? Yes, but nor bigger, neither smaller.

I've never seen a photo that matches my vision, they all seem like looking down a tunnel to me.  I don't have unusual vision, but looking at a print or a monitor screen is the limitation, even IMAX doesn't quite do it, but its close.  I'd like to see a captured image using the full width and height of my vision, which is close to 180 degrees horizontally, but much less vertically.

The matching focal length of a vision is different from different people because we see thing with 2 eyes or "2 lenses" which give us 3D vision, and because the distance between 2 eyes is different from individual to individual as well.
Camera uses 1 lens or "1 eye" which gives 2D vision.
The focal length which matches human 1 eye is about 50mm (45mm to 55mm). That's why we call them normal focal lengths.
We can do an experiment: set 2 cameras on tripods side by side @ focal length of 50mm and focus to 1 point. Stitch the 2 images, we have a wide angle picture. How wide the angle depends on the distance between 2 cameras.

Our eyes have a cones behind the pupil and rods around the outer parts of the retina. Also our brains do quite a bit of PP on the image.

We see a detailed image of what we are looking at and a not very detailed view of the rest. Our brains make this into an image that is not an accurate interpretation of the real world. For instance how often are you aware of your blind spot?

For me I'm not so aware of the outer edges of my vision, I tend to concentrate on the central area so I use a 300mm as a walk round lens and photograph wild life and details.

On the odd occasion I use a wide lens I wonder why it has not record what I saw.  ;D

The top half of this images is an accurate images of the view I was looking at. But the bottom half is what I saw.  8)
If you debate with a fool onlookers can find it VERY difficult to tell the difference.

24mm for both eyes and 50mm for a single eye. 135mm for a deep squint at something.  ;D

These answers need qualifying with 'full frame' or 'crop sensor'. I'm assuming full frame as the default.

24mm for both eyes and 50mm for a single eye. 135mm for a deep squint at something.  ;D

+1

That equates to the set of three primes I have ended up using on my OM-10, other OM lenses stay at home. I'm aiming for a similar set up for my 6D - possibly substituting a 100L macro for a 135 because of the extra versatility.

The 50 (f/1.4 and f/2.5) are the walk around lenses on both cameras (both full frame - one film, one digital), equivalent to looking in front of me without moving the eyeballs. The 24 is equivalent to standing still and taking in a scene around me, whilst the 135 is akin to focussing on a distant object with the mind's eye.
6D, 5(film)x2, 650(film)x2, Canonet QL19, EF 15/2.8, 24/2.8 IS, 50/2.5 & 70-300/4-5.6L
Fotodiox Pro OM/Eos adapter, Olympus OM-10, Zuiko 24/2.8, 50/1.4 & 135/2.8, Ensinor 28/2.8, XA/2, Mju 410
Apple iPhone 6 & iPad 2. I've only listed the equipment I still use for photography!

I believe that 35 or 40 is about how I see, but if i had to choose just 3 primes to carry, it would likely be 24, 50 & 135.  That is a great combination.

That was my prime kit for many years - great lenses  8)
