I believe that is 42mm per eye, but because we see in binocular, the central part of our vision approximates a 35mm FOV.
I wish I had bird eyes, so I could see telescopically like the eagles, or at night like the owls. But right now I'm just glad I can see at all, and my glasses can correct the faults. I do find myself using my 35mm lenses more than anything else, but I'm not adverse to going wider or narrower if the situation calls for it.

But because you're constantly scanning and filling in important bits and removing the excess human vision is extremely versatile. You can take in a whole landscape without it feeling constrained or focus on the moon without it feeling tiny.
I've heard that while walking around the vision equates to wider than 28mm while focusing on details get you very narrow perceived vision (~200+mm)

I thought instantly of 90mm especially my 90 Elmarit M. My photographs with that have a bite of emotion. Then, perhaps along similar lines, there’s medium format 75 or 80mm and also 50 Sonnar for 35mm. And my own dreams might indeed be 28mm fov. The photographs I took and my wife took of our children were mostly 35mm focal length, but I just don’t think of that FL as the one of memory. My own childhood was recorded by my father with a 45mm Zeiss Anastigmat. Some would go beyond lens type or focal length or film format and just say anything in black and white.....

I tend to to see at about a 35mm FoV on FF. That is the F/L that I usr about 90% of the time for my personal work. Don't know if that has anything to d with memories though. It's more in line with just the way I see.

Memories? Mine are associated with 24/25mm focal lengths. Probably because my first serious camera was a Nikon F, bought used, that came with a 50/1.4 and an off brand Miida 25mm lens. I fell in love with looking through the 25mm as well as photographing with it. It eventually decentered and I bought a Nikkor 24mm. I used those lenses for so much of my early photography the focal length was almost a trademark. When I recall those early photos, they were almost always done with the 24 or 25mm lenses.
Interestingly, I don't even own one today. I mainly shoot with 50mm and 35mm equivalent focal lengths and then jump to the equivalent of a 21mm.

Hi,
What we have to do is position the print so that the angle from the edge of the print to our eye and back to the other edge is the same as the horizontal FoV of the lens...
Then compare with the real view.

"someone claimed that the focal length of the human eye was 42mm".
That means that the back of our eye is about an inch and two thirds back in our heads. I guess about 23mm focal length.
42mm is sometimes quoted as the old diagonal of the negative (only it isn't but there's nice 42mm lenses out there). But, OTOH, 42mm is more or less the diagonal of a slide and once upon a time all colour film was for slides...

My memories are not static. They play out like motion pictures shot as a series of close-up and medium shots with a lot of panning and cuts. My mind focuses on details much more than the overall scene.

Yes and no.... The optical depth of focus for our eyeball is in that range, keeping in mind that large men can have eyes twice the size of small women or children, but vision isn't objective like a camera. Our vision is a perception that is subjective.
Keep in mind that our brains assemble a perception of the world with a field of view like a wide fish-eye lens, but only at very low resolution and with only gray-scale perception at the sides of our field of view. Most of our color vision is in the middle 45° of our field of view, with highest acuity and the greatest concentration of color perception in the center of our vision, in the fovea centralis, which is most acute in the center 4-5° of vision, and maximum acuity within less than 1° of our visual field.
So, our brains can automatically zoom from seeing motion in our peripheral vision (like a 8mm fish-eye lens) to a general take of our surroundings (like a 40mm general purpose lens) to a very close examination of a 4-5° segment (like a 400mm telephoto), all seamlessly blended and updated even without our realizing what's going on.
The way our eyes work is so very different from cameras that the comparison makes you wonder how we came to see anything at all, compared to the logic and simplicity of how cameras work.

Could the depth of field of focus be more applicable than the actual field of view?
I once read that the depth of field of a 35mm lens at f2.8 was closest to
the depth perception of the human eye.
Don't know about that but lately I have been using that as my guide with the 35mm lens and 50mm at f5.6 also - which has the same depth of field. For a 75mm lens on a 6x6 format that equates to somewhere around f/8 - 11.

Memories circling.
Guys, it is not about the lens (or the camera, for that matter). It is about the concept and the vision. Really. Think of painters and paint brushes. And although having the right paint brush is essential for the painter to realize his vision, the final painting is not about the paintbrush. It is about what is in the painter's head. The lenses are like our paint brushes and the argument is the same.
That's how I see it anyway.

I kind of strayed in my first response to the OP's question, so I'd like to clarify things a bit.
My first photo memories were taken with a borrowed Kodak faux TLR, and consisted of some of the most cliched images in photography, but then I was just experimenting with composition and lighting at the time. Focal length was then around 65 to 70mm.
Then I bought my first camera, a Polaroid Swinger, and who knows what the focal length of that was (and I'm not going to bother looking it up). But my memories of using that camera were of constantly wishing I could get copies of the images to share.
I then bought my first 35mm SLR, and mostly used the 55mm lens because it was a 1:1.4. I had a 28mm for it also, plus a zoom of 70-230mm which came in handy at times, but the 55 got the bulk of the work because hey, it was the "normal" lens for the camera, and you were supposed to use it that way, right?
The next three cameras had fixed focal length lenses of 45 to 50mm, and again I considered that normal, so was quite pleased with them.
Its only in my latter years that I finally realize 35mm is the focal length for me, so that is what I use for a starting point on any of my photographic jaunts. I may go wider or longer as the jaunt progresses, or never change lenses for the whole roll. Or I might cheat and mount a zoom if it's an SLR or DSLR.
So you can see, my Focal Length memory has drifted over the years, with a long period of 50mm dominating the rest.

@nukecoke - that is a beautiful list of memories and thoughts. Thank you for sharing that.
@peterm1 - your images play with selective focus, shooting through obstructions, selective blur and shallow depth of field. They do indeed seem like memories, in that they focus on details in a sea of ambiguity.
@Peter Jennings - my memories could be described much like yours, constantly moving, cutting and panning with focus on details. If I were to think of a lens type which approximates this, it would be a 24-70mm or 24-105mm at 16:9 or flatter aspect ratio.
I once stood at the bottom of Blues Point Road in Sydney, looking out at the water with Sydney Harbour Bridge in the middle. A young woman was nearby, leaning against a bright red Volkswagen, watching the same scene as the wind tousled her equally red hair. We started talking, and she said she often wished that her eyes were big enough to take it all in.
As we stood together, the sun playing on the water and the clean sea air moving through us, I wished mine were, too.

Thank you very much. You get it - that's exactly what I aim to do.
Of course almost any photo that captures something we have experienced personally, will no doubt produce memories for us, personally. But photos that have that extra "something" can produce memories that evoke something more in the nature of nostalgia. BTW I love this sequence from the "Madmen" series in which the key protagonist, Don Draper talks about using photography for evoking memories and nostalgia. It involves a meeting in the mid 1960's with the Kodak company, which is looking for Draper's ad company, Sterling Cooper & Partners, to help make an advert about their new product - the first carousel slide projector. And boy, does it nail how to use images to create memories - and evoke them later. Such images "take us to a place where we ache to go again" in Draper's words - "to a place where we know we are loved." YES,YES,YES!

But as for me, I am just a dilettante. This link below will take you to the work of Fan Ho, a wonderful Chinese photographer of the 1950s who worked in Hong Kong. His work makes me feel I was there at that time - but of course I never was. Now that is skill. The article is called " Hong Kong 1950's Memory Photography". And not without good reason...........
http://www.fubiz.net/en/2014/09/11/hong-kong-1950s-memory-photography/
And of course, my favourite, Saul Leiter who did the same for New York in the 1950s.

They are not my memories. But they are memories never the less.
Someone wrote this about Leiter's work which I think to be accurate in general about memory-making and memory capturing using photography as a tool:
"The content of Saul Leiter’s photographs arrives on a sort of delay: it takes a moment after the first glance to know what the picture is about. You don’t so much see the image as let it dissolve into your consciousness, like a tablet in a glass of water. One of the difficulties of photography is that it is much better at being explicit than at being reticent. Precisely how the hypnotic and dreamlike feeling is achieved in Leiter’s work is a mystery, even to their creator.”

What a great thread, thank you all.
Last summer I was gifted with two antique cameras that a family member bought almost a hundred years ago, so of course I had to play with them. I ended up making contact prints with the 6x9 negatives to approximate the snapshots that would have been made back in the day, and then for extra credit I toned them with sepia sulfide, like they used to do.
The result was shocking to me, but only after the toning step, which shot me into the distant future and turned me into an elderly man, looking back at my current day 15 year old.

That's a cool photo. I like it and it works as a repro of an old type of image that is nostalgic. I think it also speaks to why I have no qualms about post processing my digital images (though you have done it "old school" and that is fine). My aim is to produce a result not necessarily an image that is "true" in the sense that it is exactly the image that came out of the camera. If that's all photographers and movie makers ever did Hollywood would go out of business.
