Sensor size FAQ
These explanations are simplified on purpose. They are meant to help you reason about camera systems, not replace lab testing.
Crop factor compares a sensor's diagonal size to full frame. A smaller sensor crops the image circle, so the same lens gives a tighter field of view.
No. A 35mm lens remains a 35mm lens. Crop factor describes field of view equivalence, so a 35mm lens on APS-C frames similarly to roughly 50mm on full frame.
Equivalent aperture is a depth-of-field comparison. For a similar framing and subject distance, multiply the f-number by crop factor to estimate the full-frame depth-of-field look.
Larger sensors usually collect more total light at the same exposure settings, but real low-light results also depend on sensor generation, resolution, lens brightness, stabilization, shutter speed, and processing.
APS-C and Super 35 are format families, not one exact rectangle. Canon APS-C is a little smaller than Sony, Nikon, and Fujifilm APS-C, and Super 35 varies across cinema cameras and recording modes.
