The back wall with the very soft shadow is ten feet from the camera.  1/40 F2.8 ISO 400, continuous lighting.

What is a Zoom Lens? And why and when to choose a Zoom Lens?

Sigma offers a great variety of zoom lenses. (Lenses are not shown to scale in this display.)

A zoom lens is a type of camera lens that is offers the photographer a useful range of different focal lengths in a single lens.

Sigma offers a line of over 20 zoom lenses for DSLR photographers, ranging from wide angle zoom lenses, supertelephoto zoom lenses, and high-zoom ratio all-in-one lenses for both full-frame (DG) and APS-C (DC) digital cameras.
