According to Sonyalpharumors.com, Sony will launch a “new kind” of a Full-frame camera model.

On their website they claim that a reliable source informed them that Sony will announce two more cameras in June. 

They say, “We now have been told this:

1) The first Full Frame model appears to be the long awaited A7sII successor

2) The second model is a “new kind” of Full Frame camera!!!“

They speculate that the new full-frame camera model will be one of the following:

• Fixed lens camera with new kind of tech (new design, curved sensor, foveon sensor or whatever)
• Full Frame A6xxx styled entry level camera
• Full Frame A9r model

UPDATE: June 3, 2020

Sonyalpharumors speculates the following possibilities:

• “Worse case” scenario this is something like a RX1RII successor but with new “naming structure”…maybe a Sony version of the Zeiss ZX1?
• Best case scenario this is the first of a new E-mount camera line.

More will follow as soon we get information…
