Nokishita leaked the front image of the upcoming Panasonic GH5II. They write:
Front image of Panasonic “DC-GH5M2”. It is unconfirmed whether it will be announced on the same day as the GH5II, but it seems that the “LUMIX S 50mm F1.8” will be announced within a few weeks
The announcement will take place on May 25. And don’t worry, there is a GH6 development announcement too!
