This a well designed compact and powerful speed lite, with very simple controls when used in TTL mode. One nice feature is it fully links for my camera (Nikon D850) so you can adjust flash EV from speed lite itself - faster than digging thru camera menus and buttons. Add-on the filter kit and you have a great array of light modification options.
Only ‘cons’ is it is slightly heavy and large, nearly doubles weight of the camera - and it is a bit awkward in portrait orientation (camera held for vertical format). These short comings can easily be eliminated by using the flash off-camera with either a hot shoe extension cord or the remote slave paired.
