Overall, this Viltrox HDMI Field Monitor comes with a lot of great features and accessories making it a great bang for the buck!PROS:IO - It's got an HDMI in and HDMI output port. It's got a SD card slot for LUT import. It's got a 5 volt USBC in, with an optional DC 12 volt power plug input connector. It's got a side mount and bottom mount for mounting to a camera cage, and it's got a dedicated on and off physical switch.Learning Curve - Very simple to use, I did not look at the instructions and picked it up, mounted it to my Sony FX3, plugged in the HDMI cable, and just started using it.Lens Hood - This right here makes all the difference. If you're an event or wedding videographer, I shoot weddings all the time and in bright daylight, and it's hard to pick up proper exposure and color, but this detachable lens hood makes the HDMI monitor perfect for shooting in any condition, providing a big screen that will be protected from the sun.Interface - The almost 6 inch touch screen monitor is really responsive, but what blew me away was all of the display options, which are easily activated with a click of the round knob on the side. It's got a full volume bar, histogram, vector parade, and LUT table displayed, and because the monitor is so big, it makes it easy viewing the live feed with the addition of the display options on the screen. You can even switch to false color for really dialing in those skin tones in the field.CONS:Stability - The actual mounting bracket that comes with the monitor is a little loose and requires additional tightening once fitted to your camera, but that was a quick fix.Weight - It's listed as 280 g, and I have a DJI mavic Pro 3 which is 249 g and I have to say this Monitor is a little heavier than my drone, but again, with all of the features and attachable battery it's worth it, and you can probably trim some of that weight by using an external battery for the camera and the mount at the same time.Summary:Without having another external monitor to compare it to, it's hard to truly gauge the Viltrox DC-550 pro against its competition, however, if you are using the cameras built-in LCD screen, this is a night and day experience and this portable monitor will totally change the way you set up and configure your shots for those day of events, especially weddings. I wish I had this now for all of my weddings as It would have made exposing and checking color so much more easier. So if you're coming from no monitor, I definitely recommend this as a good first portable display for your mirrorless or DSLR camera.
