Crop Factor
Smaller sensors trick your eye by cropping images, not zooming lenses
19 hours ago
0
How does crop factor affect the images produced by a camera with a smaller sensor compared to a full-frame 35mm sensor?
It changes the actual focal length of the lens to produce a zoomed-in image.
It narrows the field of view, making the image appear more zoomed in without changing the lens's focal length.
It increases the sensor size to capture a wider field of view than a 35mm sensor.
