I started looking to replace a 2012 handheld camcorder, a Panasonic V700M. Then I started seeing many Utube videos by camera/video/photography professionals. They were near unanimous that the iPhone 14 Pro/Max cameras, both still and video, are absolutely incredible.
They were comparing iPhone 14 Pro versus frame cameras with expensive lenses, costing thousands (and even tens of thousands) of dollars. Long story short, the iPhone 14 Pro camera and tech more than holds its own against dedicated video and photography equipment costing 10x, even 20x, as much.
Those reviews sealed it. If I decide to upgrade the handheld camcorder, to heck with it, I'm simply going to upgrade the iPhone 12 mini to the iPhone 15 Pro (and the 12 mini camera/video already is very good). After seeing all the reviews, I don't think I'll ever again purchase a standalone frame camera, or video recorder.
