NO, but the whole concept is difficult to grasp.
Look at it this way, a DX lens is designed to cover a SMALLER sensor, a DX lens is designed specifically for a DX (cropped sensor body). A FX lens is designed to cover a LARGER sensor. I hope you follow this so far.
SO, if you put a DX lens on a FX body, it will not cover the LARGER sensor of the FX body and you will get vignetting in the corners of the sensors. BUT, if you put a FX lens on a DX body, the FX lens will actually spill over the coverage of the DX sensor BUT can still be used, BUT, you can only use the center of the FX lens because at over covers the corners of the DX sensor.
NOW, this is the confusing part, ANY lens on a cropped sensor camera has a crop factor of 1.5, that is for ANY lens you mount on a crop sensor camera.
Look at this lens from B&H, the Nikon DX 18-200, look at how B&H describes the angle of view, they say,
"27-300mm (35mm Equivalent)". They are trying NOT to confuse anyone, but what they are actually saying is that on a CROPPED DX body, the lens will have an angle of view of 27-300 mm.

So, any lens put on a DX body is going to receive a cropped 1.5 effect. (For either a DX or FX lens.)
So, getting back to your statement. A DX 24 mm lens on a cropped sensor camera actually has a field of view of 36 mm, not 24 mm. Any lens you mount on a DX body, either a DX or FX lens, will get a 1.5 multiplication field of view factor.
OK, the other part is this, the DX body does not see, it can only respond to any lens put on it, so, the DX 24 mm lens (which by the way does not exist) on a DX body will yield a field of view of 36 mm. And yes, a DX lens is designed to go on a DX camera, that part you understand.
The only confusing part is that you just have to except the fact that ANY lens put on a DX body will receive a 1.5 increase in it's field of view. ANY LENS.
I probably confused you further but I tried, still have not drank my coffee.

First off it's confusing because people don't understand math. (google Seattle's new math ideas to see why) Second people don't listen they hear. Hearing is thinking you know how a person is going to complete a sentence after the first half has been spoken. You finish the sentence in your head. All humans do it. Some can't seem to turn it off. Simple as that. 😂 lol

Yes, simple, yet some people make it so complicated.
To less confuse people who might look at the number reference above and think that it is the actual angle of view, adding the word "lens" hopefully reduces that possibility. (See quote snippet above.)

My point was, it is a comparison to ff/35mm.

You're probably right, good analysis, but it's a sad state of affairs when something factual and demonstrable is said to be debunked.

Abo

Okay... slight misunderstanding.

The "angle of view" of your 24mm lens on your DX camera will be similar to
the angle of view of a 36mm lens on your D750.

Abo

That's exactly it Bro

Another misuse of terms?.....I think you mean field of view.....angle of view is fixed by the lens. These two are often misused......angle of view is the angle from the crossover point (focal point) in the lens to the outside edge of the front of the lens. Field of view is a mix of lens and sensor....and also changes with distance to subject.....if you back up, that same angle of view will give a wider field of view.

Below is from the following:
https://photographylife.com/equivalent-focal-length-and-field-of-view

3) Angle of View
Lens manufacturers often publish the term “angle of view” or “maximum angle of view” in lens specifications, because they define what the lens is capable of seeing in degrees. For example, the Nikon 24mm f/1.4G lens has a maximum angle of view of 84°, while Nikon 300mm f/2.8G telephoto lens has a maximum angle of view of only 8°10′ when used on film or full-frame cameras. Take a look at the following illustration:


Nikon 300mm vs 24mm AoV

As you can see, 84 degrees is very wide when compared to 8 degrees. That’s why you can fit a lot of the scene when shooting with a 24mm lens, while a 300mm lens allows you to capture a narrower, but much more magnified portion of the scene.

The main difference between the angle of view and field of view, is that the former is an attribute of the lens, while the latter is the result of both the lens and the camera. For example, the above angle of view of 84° for the 24mm f/1.4G is only for a full-frame camera. Once mounted on a camera with a cropped/APS-C sensor, the field of view, or what you see through the camera actually gets narrower to 61°. Nikon publishes two different numbers for angle of view for lenses – “Maximum Angle of View (DX-format)” and “Maximum Angle of View (FX-format)”. In reality, the actual physical characteristic of the lens (what it sees) does not change. As explained below, the size of the sensor simply crops part of the frame, which results in a narrower “field of view”.

Thanks for the heads up.

However you failed to observe that I put "Angle Of View" in inverted commas,
as I do with the so called "Full Frame".

Apart from your oversight above, words of course can have different meaning depending on the school
you went to, or even depending on which of two different lecturers you
were tutored by in the same school.

So instead of the (inaccurate) sniping bud, do something
positive and draw us a diagram of the effect of a different
sensor and lens combination and post it in this thread.
A picture being worth (more than?) a thousand words.
You should be capable of that.

Same goes for you Longshadow.

frankraney Loc: Clovis, Ca.

Pictures are in the link, I'm not an artist...... you missed the question mark.

You are right, some words and phrases can have a different meaning...BUT. angle of view and field of view do not fall into that category... They have completely different meaning........ But some people interchange them, and all that does is add to the beginners confusion and some, like me that are not beginners, but easily confused....speaking of confused, what does upside quotes mean? And what was the inaccurate snipping?

Longshadow Loc: Audubon, PA, United States

Why?
The lens' angle of view does not change, the "captured" angle of view does,
for a different field of view.

BebuLamar

The angle of view is dependent on the sensor size (or film format).
The field of view is dependent on sensor size and distance.
It's the angle of coverage that is not dependent on either.

Joe Blow

A lens projects, a sensor captures. One does not change the other.

A 24mm lens will have the same angle regardless of what size sensor is in the camera. The size of the lens is a standardized reference* which doesn't change the angle, amount of light, or the depth of field because of the sensor. It only refers to the lens.

All lenses project an image larger than the sensor (or film). Because the edges of the projection will have distortion, they are not captured by the sensor. The sensor will capture a portion of that image and crop the rest. Even FF are cropping the projection. The projection remains the same though regardless of the sensor size.

A 24mm DX (or Canon EF-S) is not 24mm. However, because they project and capture the same size image that a regular 24mm would on a crop sensor, the rating is standardized as 24mm. The captured image on a crop camera will be the same as if a standard 24mm lens was used, approximating what a 36mm would capture on a FF.

*Originally, the size of the lens was from the front element to the focal plane (film). That was when lenses were much simpler and usually only had one or two elements. Today, most lenses bear little physical comparison between their actual length and their rated size. A "24mm lens" is a standardized reference for a size of projection, not the length of the lens

So why not use angle of projection as the standard reference? My opinion is most people suck at geometry. They prefer straight numbers over angles. It would be easier to change America over to metric than change lenses to their angle of projection. Lens length are relative anyway. Most photographers would not buy a 100mm lens if they owned a 135mm lens.
