Panasonic launched this teaser for a September 12 announcement. And the teaser is super clear with their hints:

• This is a Micro Four Thirds “G” camera
• the “new phase” means this will be Panasonic first MFT camera with phase detection AF
• Announcement on September 12 at 22:00 Peking time (That’s 3pm London time).

I am pretty certain we will get a new G9II. Hopefully this will revive some enthusiasm in the MFT realm!

This could be the first images of the new GFX100II.

• release on September 12
• New 100-megapixel BSI back-illuminated sensor

I just heard from a source that for some unknown reasons Nikon moved the ZF announcement to early September. My guess is that Nikon wants to see what Sony will announce on August 29 first :)

Asobinet leaked the first images of the ZF.

A Japanese photographer known to test Nikon cameras ahead of their announcement did shortly show a Nikon camera in his latest video (from minute 1:50). The reason why some do believe this is the new Nikon ZF is that it mounts the 40mm f/2.0 lens which is rumored to be available as a kit lens option on the new ZF. The rumored specs on Weibo and Asobinet are:

• Announcement in August
• Ship by end of 2023
  
• Color: Black
• 24.4 megapixel back-illuminated CMOS sensor
• 700g
• Size: 144×101mm
• Continuous shooting speed: ~30fps
• 4K 60p
• USB-C PD compatible
• ISO 100-64000
• EN-EL15 battery
• Z logo moved left
• Dual memory card slots
  SD + Micro SD
• Pixel shift shooting
• Improved AF compared to Z5/Z6II
• August-September announcement, launch by the end of 2023
• Body only price: $1,999
• One of the kit lenses is the Z 40mm F2 (SE)
• Design/layout is very similar to Z fc
• Equipped with a small LCD screen for aperture display on the top
• A third function for (still image/movie +) monochrome mode has been added to the sub-lever of the shutter speed dial
• Has a small grip/bump like Df
• Better build quality compared to Nikon Zfc
• vari-angle monitor
• Codename N2137

Looks like the real deal!
