Ultra-Wide to Short-Portrait Zoom. The Panasonic Lumix S 20-60mm f/3.5-5.6’s focal length and 6.0-inch minimum focusing distance make it a particularly great option for close-up photography and for shooting indoors when space is at a premium. The rounded nine-blade diaphragm helps to produce pleasing bokeh. Its f/3.5-5.6 aperture isn’t anything to write home about, but it’ll get the job done in good lighting. If you’re shooting indoors or in low light, you’ll want a flash and/or tripod. Using an APS-C camera? You’ll get a 30-90mm equivalent focal-length range.

L-Mount Alliance. This wide-diameter lens mount is a joint collaboration between Leica, Panasonic, and Sigma that’s focused on a line of premium cameras & lenses in a mirrorless format. At 51.6mm mount diameter and just 20mm flange distance, the L-mount is well-suited for fast-aperture full-frame optics with compact dimensions.

Stepping Autofocus System. This autofocus system uses a stepping motor to provide fast, accurate, nearly silent autofocus performance for still and video use. You can use the AF/MF switch to easily toggle between autofocus and manual focus modes.

Premium Optics. This lens’s nine-group/eleven-element optical formula features three extra-low dispersion elements and two aspherical elements to reduce spherical aberration and distortion, producing sharp, clear, color-accurate images.

High-Quality Build. Its metal barrel construction provides a solid, yet lightweight feel, while its splash-. dust-, and freeze-proof design lets you work in inclement weather conditions down to -14° with confidence.
