Hello everyone, I am of the opinion that the term “normal lens” or “standard lens” should be linked to the magnification factor rather than the angle of view.

I would like to suggest a simple experiment to everyone from my own experience: If a lens with a 50mm focal length is used on a camera (regardless of the sensor size) you experience the following: The enlargement of the image corresponds exactly to the enlargement of the eye. To do this, simply leave the other eye open without the lens-camera system and walk around. If you try this with a different focal length, deviating from 50mm, this experience quickly becomes uncomfortable or leads to dizziness / headaches.

How much the viewing angle is restricted by the crop of the camera sensor is irrelevant here. The only important thing here is the magnification factor, which is determined exclusively by the focal length! This is also understandable for everyone who connects his 50mm “normal lens” to a crop sensor instead of 35mm format. The experience of being able to take pictures with both eyes open will continue to be pleasant throughout the day.

Unfortunately, I have not yet identified any sources for this, but I am afraid that the original references have neglected the connection of the magnification factor via the angle should only be related to the small image format 24x36 (viewing angle). In addition, the crop sensors and, more recently, the "equivalent focal lengths" were added, which have obscured the true relationship between the "normal lens" or "standard lens" to the magnification factor and therefor the focal length alone!

In any case, you can't walk around with a 33mm lens on an APS sensor or an 18,5mm lens on an 1’ Sensor with both eyes open without irritation!

I ask everyone to try this out for themselves if possible and to form their own opinion. I would be grateful for any of the sources for the connection between “normal lens” or “standard lens” to the magnification factor and thus to the 50mm focal length. Sincerely
