Light loss by placing a full frame lens on a crop sensor camera?

4 years 4 months ago #669551 by Liem Stailey
Now I know this doesn't apply to me, right now because I have a full frame camera, but I'm just trying to understand how this works.  I tried searching, but didn't find the specific question regarding light loss when placing a full frame lens on a crop sensor camera.

Well I might be getting a second body from a buddy of mine, it's a Rebel.  So just thinking ahead to see how this would benefit me or be a PITA considering all my lenses are full frame. 

Thanks for the help, or rather understanding!

There is no light loss. Where did you get that idea?

Agreed… this is nonsense!

Light is free… capturing it is not!

A lens is a lens and it doesn't care what is behind it, whether film, sensor, carboard, paper, tin, full frame, crop or anything else. The image coming out the rear of the lens is the same. The size of the sensor just determines how much of that projected image is captured. Images are ALWAYS cropped even with a full frame sensor. Nothing captures the full image circle unless you put the lens on a medium format camera.
