This new Panasonic lens is rather a new version of the 14-140 mm lens that was seen forst with the GH1 at the time. Here is the LUMIX G VARIO 14-140mm/F3.5-5.6 ASPH / POWER OIS. Its main interest is compactness by the capitalized efforts of Panasonic engineers who have succeeded in miniaturizing the lens dramatically. Its autofocus is also compatible with the latest generation of contrast detection autofocus recent implemented on Panasonic mirrorless cameras like the GF6.
The LUMIX G VARIO 14-140mm/F3.5-5.6 ASPH. / POWER OIS is a more compact version of the 14-140 mm lens that we know so far in the Panasonic Lumix range of G lenses. This lens, you will understand, is available in micro Four Thirds mount and gets a new autofocus motorization compatible with the new AF system of the GH3 or G6 which allows to operate up to 240 operations per second of dichotomy to find the right focus in no time. I had the opportunity to get my hands on the GF6 and G6 recently with the 14-140mm and it is clear that their focus is made in the blink of an eye.
Once mounted on a Lumix G camera , the LUMIX G VARIO 14-140mm/F3.5-5.6 ASPH. / POWER OIS gives an equivalent focal range to a 28-280 mm. The lens itself is stabilized through an optical stabilization system (Power OIS) Panasonic designed to correct both small movements such as vibrations and larger amplitude of the camera.
Panasonic reminds us, and they are right to do so, that this new lens complements a young, yet huge, range of lenses for Panasonic Lumix G MFT cameras. A range already very rich range and the most comprehensive lens range of any other mirrorless camera system. The work done by Panasonic since 2008 and the launch of the Panasonic Lumix DMC-G1 is impressingvly huge with the development of a true optical ecosystem when competitors failed in a way to do so (Nikon 1, Sony NEX, Samsung NX, etc.. have poor lens offers).
