Every slr with an eye level viewfinder (instead of focusing on a waist level ground glass) has optics in it. It is an MLR by your wording. Your eye has to focus on the reflection of a ground glass within an inch or so, or else is viewed through a lens that makes it possible to see what the camera sees. You wouldn’t be able to focus with your eyes if there wasn’t another lens. In other words, your “standard” lens is an artifact of the optics chosen to allow your eye to see the image. In terms of what your eye sees: The FOV of what you are focusing on with your eyes is narrower than a 50mm lens. The FOV where your eyes can recognize symbols (can read letters) is wider than a 50mm lens. The FOV that your eyes can see from periphery to periphery is drastically wider than 50mm. Quite simply put, the fact that on some cameras you can shoot with both eyes open at 50mm is an artifact of design, not some natural law. This is proven by the fact that there are cameras where you can do this with a 35mm lens or a 60mm lens. Camera manufacturers settled on calling 50mm at 1.0x magnification a standard view is arbitrary. There is precisely nothing behind the common belief that 50mm is the same view as your eyes. It isn’t. You can keep insisting otherwise, but it is in contradiction with physics and nominal human anatomy. | ||

well, why don't you bring your physics and human anatomy arguing-from-first-principles over to wikipedia and let's see how long your changes last on that camera page :) good luck! https://en.wikipedia.org/wiki/Single-lens_reflex_camera opening paragraph "In photography, a single-lens reflex camera (SLR) is a type of camera that uses a mirror and prism system to allow photographers to view through the lens and see exactly what will be captured... SLR technology played a crucial role in the evolution of modern photography...the rise of mirrorless cameras in the 2010s has led to a decline in SLR use and production. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image." what you see through the viewfinder is what the camera will take a picture of; you can change lenses so it is not always neutral. but if the zoom of the lens it neutral, what you will see through the viewfinder is neutral, and that occurs at 50mm for a 35mm camera | ||
