The new lens is 22% lighter (695g vs 886g) and shorter (120mm vs 136mm) than its predecessor. Sony claims it is the most compact F2.8 standard zoom designed for full frame cameras. The lens is weather sealed and costs $2300. It will be available in June. Note that the original 24-70mm will remain on the market but at a reduced price.

New on the outside are the two function buttons and the aperture ring that can be de-clicked with the dedicated switch. The iris can be locked and there is a smooth / tight switch to control smoothness of the zoom ring. The lens hood includes an opening to access circular polariser filters.

The focus mechaniams is internal but the zoom mechanism is not (the barrel extends when zooming in). Sony says focus breathing is minimal.

Panasonic Firmware Update

Panasonic has released a series of new firmwares for the GH5S, GH5 II, GH5, G9 and G85/G80. It fixes a few minor issues related to a green or magenta colour cast in the live view while shooting, and another issue related to the use of electronic stabilisation with wide-angle lenses.

You can download the firmware from the Panasonic support website.
