It comes with a lens supporter, Fotodiox Pro B4 lens adapter and all original factory accessories in it’s original retail box. This is not a 4K version!
I will also include an Anton Bauer battery adapter but the power cable is too short, so you will have to buy a small extension. You still have the original 12V power supply included with the camera if you don’t want to use the battery. The camera is fully tested, no problem were found.
