A £300 camera is next level? But a £800 one isn’t?
Any camera will last 10 years and all of them will look ancient in 10 years in tech terms. Technology is moving at a really fast pace in video, the best ones will makes the video more steady, the it focuses and track faces, 4K, WiFi etc etc. I really don’t think these handycam style camera will stay as you can shoot video in any compact camera these days.
