Sony's A7 IV camera arrives with a 33-megapixel sensor and 4K 60p video

Sony has finally revealed its mainstream $2,500 Alpha A7 IV full-frame mirrorless camera and it looks to have been worth the wait. Borrowing technology from the recent A1 and A7S III models, it offers large improvements over the A7 III introduced well over three years ago. Key features include an all-new 33-megapixel sensor, 4K 10-bit 60 fps video, new AI autofocus tricks and a lot more. The A7 IV resembles the A7S III in terms of size and layout, but you can now select between still, video and S&Q (slow and quick) options with a new dedicated dial below the mode dial. Each mode completely changes the settings and control layout of the camera to favor either photo- or video-centric controls.
