The GR-AX780 is one of the last JVC VHS-C camcorders. Its manual is dated 2003, more than twenty years after JVC introduced the compact VHS cassette in 1982, and by then most of the market had moved to MiniDV. That's part of its appeal. It's a simple, late analog camera, with a 16x zoom, a 1/6-inch CCD and a black-and-white viewfinder, and it came with the adapter that lets its tapes play in any VHS deck. There's no flip-out screen and no S-Video, so it's built for shooting and handing the tape to a VCR. For a newer VHS-C camera that's still plain to use, it's a good place to look.
Tape check
Should come with it
Check the listing photos against this list, and ask the seller about anything you can’t see. A missing piece should come off the price.
No model-specific faults are documented. Original packs are old by now, and a camera that only powers on hasn't proved its tape transport works.
New to old camcorders? How to check a used camcorder covers the tape transport, heads, screens and power, and getting footage off a camcorder explains FireWire and analog capture.
We haven’t been through this model’s listings yet. Search eBay and run every listing through the checklist above. Ask whether it has played and recorded a tape (not just powered on), for a photo of the screen showing a picture, and for a close look at the lens. Pass on any seller who won’t answer.
