I dont mean when for example 35mm on a crop sensor “equals” a 50mm on a full frame camera. My question is a bit weird, here we go.
So i have a 18-55mm lens (on a crop camera) and people say that 50-55mm is the focal length of the human eye. Here, my experiment comes into the play:
My camera has a 1.5x crop factor so 35mm looks like 50 mm on a full frame because of narrower field of view right? So when people say field of view of a 50mm on a full frame is the same as your eye, my first thought is 50mm on a full frame = 35mm on my camera. Then what i do is i take my camera put it on 35mm and then look at the vizor. What i expect is no zoom at all but the objects look smaller in the vizor (so fov is higher). When i put my camera at 55mm, the objects size match up with exactly what i see. But from what i learned 35mms should be like a 50mm on a full frame therefore it should match my eye.
So here comes my question:
Are the numbers of focal lengths on my lens already multiplier by 1.5x ? So do i have to subdivide the numbers to get the full frame equivalent ?
Sorry for spelling mistakes.
The viewfinder on your camera should show you what the camera will capture, so the same lens on a crop sensor will show a small field of view in the viewfinder than it would through the viewfinder of a full frame camera.
The viewfinder are different in the same way the sensors are.
Exactly the viewfinder is not the problem.
I think it’s just OPs perception of their vision, it really depends on how much of your peripheral vision you notice, and expect to be included in a “normal” fov. Also your eye constantly darts around in a scene and assembles the image as you perceive it, so it doesn’t actually make much sense to compare to focal lengths of camera lenses.
Just shoot with whatever lens you like.
