Sony manager Yosuke Aoki has officially confirmed they will be present at the May 2020 Photokina event:
“Sony is very glad to be part of Photokina again next year. Photokina 2020 gives us the opportunity to present our latest innovations and to maintain a direct dialog with all Digital Imaging Lovers. Sony is looking forward to seeing you all in Cologne.”
Photokina starts on May 27 and I will be there :) I bet I will see the A7IV…and hopefully the A7sIV too!!!
