Panasonic Adds Telezoom To Lumix S System

-

The line-up of L-mount lenses continues to grow with Panasonic adding a new telezoom to its Lumix S full-frame mirrorless system. The Lumix S 70-300mm f/4.6-5.6 Macro OIS features a weather-proofed constructi­on that not only protects against moisture and dust, but also allows for shooting in polar climates down to -10ºC. There’s also a fluorine coating on the exposed surface of the front element to better repel moisture and grease, and allow for easier cleaning.

The new 70-300mm’s optical constructi­on comprises 17 elements in 10 groups, includes one ultra extra-low dispersion type (UED), two extra-low dispersion types (ED) and one using ultra-high refractive index glass (UHR). Collective­ly, these special elements correct for axial chromatic aberration at the telephoto end and chromatic aberration of magnificat­ion at the shorter focal length end. The lens is compatible with the current version of Panasonic’s Depth From Defocus (DFD) autofocusi­ng which samples at 480fps. The minimum focusing distance is 54cm which gives a maximum magnificat­ion ratio of 1:2 (i.e. half life-size) at the 300mm focal length. The diaphragm has 11 blades to give a more circular aperture and smoother out-of-focus effects. Panasonic says the lens’s focusing mechanism minimises focus breathing (a variation in the image size as the focus is adjusted) and also focus shifting when zooming, both of which can be problemati­c when shooting video.

The lens’s optical image stabilisat­ion supports Panasonic’s Dual IS system, which works in concert with in-body image stabilisat­ion to give five axes of movement and up to 5.5 stops of correction for camera shake (depending on the focal length).
