The firmware update for the three Panasonic LUMIX top models GH5, GH5s and G9, announced for May 30, does not sound unexciting: Besides a new monochrome image profile "L. monochrome D", a new Grainy mode simulating analog film grain is also planned.
The new "Focus ring lock" function can freeze the focus point while simultaneously deactivating the focus ring to prevent accidental adjustment.
"Live View Boost" was already announced at the presentation of the GH5s and is now available: This allows you to brighten the display preview considerably when filming dark motifs in particularly dark places.
In addition, the zoom factor of the preview magnifier ("Manual Focus Assist") on the GH5 and G9 has been increased to 20x.
Last but not least, it sounds exciting that object tracking via autofocus during video recording has been further improved. The AF speed at 180 degrees shutter angle should then also be faster. The moving sensor should also stabilize the image even more reliably with certain lenses.
