Sony has quietly updated their a7R III and a7R IV cameras with improved LCD panels. The newly designated a7R IIIA (ILCE-7RM3A) & a7R IVA (ILCE-7RM4A) will get an upgrade from a 1.44 million dot LCD to a 2.36 million dot LCD. The new LCD is slightly more power hungry resulting in a rating of 10 fewer shots per NP-FZ100 battery based on the conservative battery specs for each camera. The EVFs remain unchanged in both cameras.
Listings for the new model ‘A’ cameras have not yet shown up at US retailers as of publication.
