Nikon & Canon crop cameras have been out for over 15 years now. But different sized frames isn’t new to digital. Even back in the film days, we had 110, 126, 35mm, half a dozen sizes for medium format, and a few for large format. It still always amazes me how much the concept of capture size still confuses some people.
This video from photographer & YouTuber Blake Evans (aka biscuitsalive) hopes to dispel some of those myths and clear up the confusion. It does goes very in-depth into all the ins and outs of sensor size, focal length & field of view, as well as aperture & depth of field. So it may have you asking more questions than it answers!
