Question 6

In product animation for US e-commerce, why is a 85–135mm equivalent focal length often preferred over wide-angle lenses?

Accepted Answer

Longer focal lengths minimize perspective distortion, making the product look more true to its real shape

Answer

Wide-angle lenses render slower in 3D

Answer

Wide-angle lenses cannot render transparency

Answer

Longer focal lengths automatically add depth of field
