Newark, NJ—Panasonic introduced a wide-angle, large-aperture, fixed-focal-length lens: the Panasonic Lumix S 24mm F1.8 (S-S24). It is the third addition to the series of four f/1.8 large-aperture lenses based on the L mount.
Four f/1.8 fixed-focal-length lenses from the Lumix S series feature a common size as well as position of control parts to provide practical advantages in use. The lenses include the 85mm (S-S85); 50mm (S-S50); and the new 24mm (S-S24). Their center of gravity is also similar, which makes it easy to exchange lenses with minimum balance adjustment when the camera is on a gimbal. In addition, their descriptive performance is consistent. Also, a uniform 67mm diameter enables the use of common filters.

The Lumix S 24mm f/1.8 is employs 12 lens elements in 11 groups. They include three aspherical lenses, three ED (extra-low dispersion) lenses and one UED (ultra-extra-low dispersion) lens. The use of three aspherical lenses realizes high descriptive performance and beautiful bokeh, aided by a 9-blade circular aperture diaphragm. In addition, the ED lenses and the UED lens suppress chromatic aberration.
What’s more, the new lens is an option for various situations ranging from landscapes to snapshots, while taking advantage of the wide angle of view. The lens is also capable of smooth, silent operation to work with the camera’s high-speed, precision contrast-AF system with a sensor drive at max. 240 frames per sec. 
“For the non-linear setting, focus is shifted with a variable amount according to the rotation speed of the focus ring,” notes Panasonic, “while focus is shifted with a designated amount according to the rotational quantum of the focus ring for the linear setting.” Photographers can also select sensitivity from 90º to 360º by 30º to enable intended focus operation.
The S 24mm f/1.8 is also a tool for video recording. It features a mechanism that suppresses focus breathing—a fatal problem of interchangeable lenses designed for still image photography. Further, its micro-step aperture control for smooth exposure change helps users record professional-quality video.
Compact and light weight, the new lens pairs well with the S5, the smallest Lumix full-frame camera. In addition, its dust/splash-resistant body withstands use under harsh conditions, even at 14ºF.
The Panasonic Lumix S 24mm f/1.8 (S-S24) lens will ship to retail in mid-October. It will have a suggested retail price of $899.99.
