No, on a DSLR its a mild telehoto. 35mm is about natural size

So my longest lens (200mm) is roughly 4x natural size.

6x.

My binoculars are 10x42 which gives a lot more detail.

I am saying that if you strap a hand held 400mm on a camera you will
get blur.


You can always enlarge a good lenbs image several toimesÂ* as well


Or with fast enough film speed to go for uber short exposures, grain


Â*So 35mm camera doesn't have enough magnification (unless I want to
spend
several hundreds perhaps thousands on a very long lens) which is then
only
usable with a monopod or tripod and is also a big thing to lug around.

staring from false prenises will always lead you to a false conclusion

Â*Small format cameras with LCD screens on the back are fine if on a
tripod
and also not having bright sunlight shining on the screen.
Ditto mobile phones.
Both give pretty shaky results if hand held at 10x or higher.
There is also the "just a minute while I dig out and power up
and...****,
missed it!" situation.
Not really comparable to leaning it on your window cill.
Â*So, my use case is that I out walking in the countryside, am looking
through binoculars, see something fleetingly visible and want to
capture a
picture.

...Is a fantasy.

I have large and small cameras and a mobile phone with a decent
camera but
these aren't working for me.

Perhaps that should tell you something

Speaking from a Brownie box camera expert POV. Is there a marketing
opportunity here?
What would be the practical difficulty of fitting a digital camera
sensor to binoculars and leading the output to a socket feeding a
storage device?
I understand high magnification, camera shake and exposure time issues
but can also see the originators point about the convenience of
recording something only seen/found through using binoculars.

I am sure nikon could knock up something in the 5grand level or so

But fitting autofocus auto exposure user selectable film speed , a
memory card holder and a usb plug and vibration reduction in a pair of
binocs would probably render them too heavy for usability, too expensive
to risk and in any case inferior to a digital camera
