In all my years phtographing I newer recall hearing this term describing the lens
Ok I now own the bridge camera and looking over the web to see the images taken with it. So I came across some new to me eh terminology, where instead of the focal lenght the milimeter lenght is given eh. But the thing is that I dont see anywhere on my camera setting for such a focal lenght.
Example; 4.3mm huh? my lens goes from 28- 3000mm. How does one get to that wide angle (4.3mm)
thats some fishy eye eh?
I am sure someone here will have an reasonable explanation as this terminology might have someone else confused too.
Stay safe, fine folks and use rose coloured lens in mean time1

Relative to sensor size?
What you typed doesn't say a lot, or make any sense.
What was the reference to 4.3? How was it used?
Context means a lot.
(Always been mm.)
Which bridge camera will help. But, you need to remember the sensor size of your cell phone or bridge camera is a very small fraction / size when compared to the reference 35mm frame of film (aka full-frame). So, when that small sensor 'crops' to an equivalent full-frame field of view of a much longer full-frame lens, you get these wide zoom ranges. When you crop from the very small center of an image, even at 4.3mm, the fisheye effect is not evident.
The Canon G9X here on my desk next to the keyboard has a range 10.2mm to 30.6mm, for a 35mm Equivalent of 28-84mm. The 10.2mm images have no unusual distortion. The 1-inch CMOS sensor inside the camera crops the center where that fisheye distortion is not evident, particularly when the camera is parallel to the subject. Distortion correction the camera applies to the JPEGs helps too.
You should never read any numbers on a bridge camera ... thaz why one chooses that type of gear (eh?)
There acoarst is a technical explanation, but learning it would undermine the whole bridge camera experience of freedom from the nitty gritty, eh !
Quite often there are techie looking numbers and such sprinkled about on these cameras cuz the marketing department thinks it helps justify the price. But once you’ve paid the price, what you’ve really bought is the freedom to ignore all the numbers and just enjoy photography. Good deal, eh ?

4.3mm is the actual focal length of the lens - 28mm is its full-frame equivalent.

Sufficient context is given in the term “bridge camera” itself.
4.3 is quite typically the minimum FL on a bridge camera but that is useless info to the users. Doesn’t matter what brand or model ... it’s so common it’s nearly universal.

Actually, the lens has a FOV or AOV as a 28-3000
would if it were on a full frame. But it actually has a focal length much smaller, starting at 4.3mm.

(I have no idea what the focal lengths (or equivalents) are on my bridge camera, I just take pictures with it. Wide, medium, or telephoto, as desired.)

FOV ... AOV ???? LOL !!!!!
Bridge cameras don’t have those. They have Kinda Wide Enuf to Reeeeeeeally Freakin Long. If one just toadally gotta get geeky I spoze one could call that KWE and RFL ... for talkin the photo talk with the photo dudes.

Yup !
On my “movie lens” I painted crude symbols for Wide and Long. Canon did very neatly put tiny numbers on there but hey ! Makin movies ! Kinda busy !

THAT is my fave graphic ! Every time you post it I download it again ... cuz I keep forgetting where I filed it and wtf I named it :-(

The 28-3000 is the equivalent angle of view on that tiny sensor as compared to a 35 mm sensor/lens combo.
The 4.3 mm is the actual length of the the lens - probably at the wide end.
Translation=that camera has a TINY sensor.
Although the OP said 28mm to 3000mm I think he meant the Nikon P1000 (which equivalent focal length to FF is 24-3000mm) and the lens actual focal length is 4.3 to 539mm.

To be more precise, the typical bridge camera has a sensor which is roughly 1/6-th of a 35mm slide - in each dimension ..... 1/6-th of the height of a 35mm slide and 1/6-th of the width.
