The Freefly Wave Camera is regarded as one of the greatest camera for broadcast. It a S35 (APS-C) camera with a locking E-mount inside a 6061-grade aluminum housing (150mm x 97mm x 47mm, 716g). Because of the shallow flange depth, a ton of lenses can be adapted to fit the camera. However, it seems to be a mechanical E-mount only.
Frame rates go up to 420 fps in 4K, and up to 1440 fps in 2K. The Wave uses a built-in NVME SSD for storage, and the 2TB version allows for 35min of recording time at the above frame rates. The NVME storage is apparently user-exchangeable. So when larger certified drives are available, recording capacity can be increased. Right now it can be ordered with 1TB or 2TB storage.
For scientific applications, the Wave can shoot at faster frame rates, but the height of the image gets cropped down to a horizontal strip. At the maximum of 9259 fps, the recorded image is only 128 pixel high (2048×128). Exact frame rates can be dialed-in and the frame rate can be synchronized externally.
