Early in the summer I upgraded the camcorder I use to make my videos from an HD one (JVC GY-HM100U) to a 4K camcorder (JVC GY-HM250U). There is quite a bit of difference between the two camcorders besides just the video resolution. The ergonomics of the newer camcorder is significantly enhanced but, interestingly enough, not every change was an improvement. This video compares the two camcorders, and covers features of professional camcorders that one should consider not only when purchasing either of these ones, but also when looking at the camcorders from the other major brands such as Canon, Sony and Panasonic. Unlike many camcorder review videos, I have placed more emphasis on features of the devices rather than presenting video clips showing what pretty movies the camcorder can make. For a list of USB WiFi and Ethernet Adapters that I have found to be compatible with the GY-HM250U : https://electromagneticvideos.blogspot.com/2023/11/wifi-and-ethernet-adapters-that-work.html
