That is likely the only bigger A or E-mount related news of the NAB show: The Sony NEX_FS700 E-mount camcorder can shoot 4K with the new external HXRIFR5 unit. Anyway, don’t worry, regular A and E mount rumors are coming soon on SAR and Hasslebald and Zeiss should announce their E-mount stuff soon too!
