1/2.3″ This is the standard image sensor size in GoPro cameras. 1/1.9″ New image size in Hero11 Black and Black Mini. 1/1.7″. 2/3″. CX (Nikon) APS-C. 35 mm (Full frame) This is the standard sensor size that all others are compared against. The crop factor (see above) is used to compare other sensors against this size.
The Canon EOS 90D is an APS-C camera so it is a ‘crop-sensor’ camera. And since it is a Canon crop sensor camera, the sensor size is (22.3 mm x 14.9 mm). This is basically the same sensor size as other APS-C Canon cameras like the Canon EOS 60D or Canon EOS 70D. How Does It Compare To A Full Frame Camera?
Many people often question full-frame sensors to crop sensors, wondering if full cameras are better for videos. Full sensors have lower noise, megapixels, and capture more light. Unfortunately, cameras are missing both the 4k and 1080p resolution, and that is where the real issue begins with sensors featuring higher MP than what the videos need.
However to get the same framing on a crop-sensor vs. a full-frame sensor, you'd need to change the distance if using the same lens on each camera. In other words, a 57mm focal length on a 1.5x crop sensor, should provide the same perspective and framing as an 85mm focal length on a full-frame sensor if shot from the same distance.
Full-frame sensors will always be a little better than cropped sensors if they’re both from the same generation. However, this difference is far more pronounced at higher ISOs than lower ISOs. In fact, at ISO 100, (or whatever is the base ISO for your camera, such as 64, 160, or 200) …the newest generations of crop-sensor cameras have
