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.
Many slrs digital or not have what’s called a viewfinder magnification ratio. So if that is 0.8, a “normal” lens will show a reduced size of the object when compared to the naked eye. A slightly longer than normal lens will match up, but appear to give a slightly more compressed view. Keep in mind that perspective is SOLELY based on your shooting position however… You can shoot a 50 on a full frame, switch to a 100mm, crop the 50 image to match the 100, and you have the exact same perspective.
It why I’m a firm believer in zooming with my feet. Zooms just fine tune cropping in camera to allow more of the sensors pixels.
Oh if there is a .8 magnification that explains why i see it like that. Oh and i would like to move but sometimes i cannot move through the car window lol
When photographing bison, it’s best not to zoom with your feet. Use a supertelephoto lens.
Sure. I’m just saying I fine tune the relationships between objects in the frame by foot. Crop with zoom. Of course there will be situations where you don’t want to get too close. There are other situations where you would. Flowers don’t bite,.and maybe I want lots in the background.
