Why don't you keep your eye on the ball and explain how binoculars and fov works, what 'fisheye' means and what dots are for. Preferably with illustrations.

you said they're (binoculars and FoV) the same... and

define: "usual"




... why not you show us how they (binoculars and FoV) are the same? You made the claim... you back it up

I won't play this game. YOU said that going to 30 fov from 70/90 fov produces a 'fisheye' view! This is clearly wrong. Lower fov's do not produce a fisheye view, not to mention that fisheye implies a very large fov, not low fov. It is up to you to prove otherwise.

For example, fisheye lenses have about 6-20mm focal lengths, with fovs as high as 180-220 degrees. By contrast, telephoto (ie, zoom lenses) lenses have focal lengths of 85-300+mm and fovs from 30 degrees to less than 1 degree. In other words, lower fovs mean a zoomed view, and higher fovs mean a wider, even fisheye view, not the other way round!

Your knowledge is so rubbish here you don't even have the right direction for wide vs zoomed views and fov.

I will, as soon as you show me why I won't be wasting my time explaining it to you - nobody else has questioned this or desired an explanation. Everyone except you seems to understand the concept of a 1:1 view and why it is useful - and you're not exactly receptive to new ideas.

It seems you're the only one "playing a game"

Where did I say this and what did I say?

What... you can't explain how, how FoV and bionoclars, are the same??

Right here. You said it yourself - no zooming and fisheye views! Care to explain?

I could amuse myself by asking you why I would want to switch to a smaller fov if it didn't actually zoom the view (and make dots bigger, as you claimed), but its just so obvious that you won't take the hint.

As for explaining binoculars and fov - I stand ready, if you are willing.

From the perspective of PHOTOGRAPHY ~


1.3 Barrel and Pin-cushion distortion
The two typical lens distortion that occur are called barrel and pin-cushion distortion. They are named by the effect that they have upon an image, as shown in Figure 1.4. Barrel distortion is found in wide-angle views and it is the result of the squeeze that is applied in order to fit the image in a smaller space. On the other hand, pin-cushion is found in telephoto because of the stretching applied in the image in order to feet the space. The squeezing and the stretching of images vary radially due to the design of the lenses, making these distortions visually most prominent at the image corners and sides.





However... from the perspective of PROJECTION (which is what the image on the monitor is) the opposite applies.

I'm sorry that you seem to have forgotten that you made the claim - you need to present your reasoning there.

The opposite applies? Bullshit. Link for THAT claim please.

Oh, and - is a lower fov a zoomed image or not?
