Update: Bob Martin now confirmed that this is a7R IV, not the a7 IV.
Sony photographer Bob Martin recently posted an image about Tokyo 2020 in Japan. He said this sample image is taken by the upcoming Sony a7 IV, so is this just a typo or he is really testing the Sony a7 IV. Stay tuned.
Olympics, Tokyo 2020 will start in July. Shot on a A7 mk4 and a 55mm taken today in Tokyo.
