15sFocal Length Comparison Demo with Talking Girl
A four-shot sequence demonstrating how 24mm, 80mm, 135mm, and 200mm focal lengths change the look of a frontal eye-level medium shot of a girl. Each 2.5-second segment cuts to the next lens, with the subject speaking, waving, spinning, and tilting her chin to camera.
