I've checked this several times as I almost always have the binoculars with me, camera or no camera and the image looks larger than the 420mm the above lens + TC affords me.

It doesn't matter what the print size is, or how far the viewing distance, or the net magnification through the viewfinder. All else being equal, the subject will be 8x as large (linear dimensions) with a 400mm lens as with a 50mm lens.

Remember that the definition of a ray specifies that rays are drawn perpendicular to the wavefront. All of the rays associated with a spherical wavefront will ...

You need to take the camera film or sensor size into account to make a proper calculation. For instance, a 300mm lens on a 1.5 FOV factor digital camera would be roughly equivalent to a 9x binocular. And a 300mm lens on a 4x5 would be roughly equivalent to a 2x binocular.

My Nikon wide-field 7x35 "E-type" binoculars have a 7.3 degree FOV, which is comparable to the diagonal FOV of a 350mm lens on a 35mm camera. The 8x35 "Superior E" have a FOV of 7.5 degrees. This hardly qualifies as "much bigger" than a camera's view. Read further for the justification (sorry, no pictures).

Starting from your sensor, select the desired object field x*y [mm²]. Decide on a working distance and, if necessary, other special features of the desired lens.

I think it is confusing to compare the appearance through the viewfinder with the same view through binoculars of "comparable" power. Most viewfinders have a net magnification factor less than one with a "normal" lens, and different cameras can vary significantly. This, of course, makes no difference whatsoever in the final image. Cameras don't make very good telescopes, but that's not what cameras are for.

2024726 — Below are some of the best lighting prompts in Stable Diffusion, followed by tutorials to use denoise offset Lora for high dynamic range images.

If one accepts that a 50mm lens is considered "normal" (a tradition based on the diagonal dimension of the film frame), then a 400mm lens would be the equivalent of 8x. By this criteria, a "normal" lens for a Nikon DSLR would be about 35mm, and an 300mm (266mm) lens would be the equivalent of 8x.

Although I am definitely not an optics expert, the 50mm figure in the above answers assumes you are comparing magnification relative to a normal lens on a 35mm full frame camera.

I don't know if I'm adding any wisdom to this discussion but I have the impression that the image size in my 8X binoculars is larger than the
