See how focal length and sensor size change what ends up in the frame. Same scene, same spot, different lens.

How this works

The scene is an AI-generated illustration, not a photo taken with the selected gear. We treat it as an 8mm full-frame view and crop it by focal-length ratio, which shows how much of the scene you get and nothing about sharpness, distortion, depth of field, or autofocus.

Angles assume an ideal 36 × 24mm full-frame sensor and the catalog’s rounded crop factors. Real framing shifts a little with focus distance, recording mode, lens corrections, and stabilization. Pixel estimates assume a 3:2 crop. The lens’s focal length and f-number never change.
