Is the ZV-1 II worth it over the original ZV-1?

If you film yourself handheld, the wider 18mm lens is the main reason to pick the II. The original gives more reach at the long end. Both share the same sensor size and 4K recording.

How does it compare with a phone for vlogging?

It offers a real zoom, a larger sensor than most phones and better stabilization for walking shots. A recent phone is simpler and always with you, but the ZV-1 II handles low light and background blur better.

Does it have a headphone jack?

No. There is a microphone input but no headphone output, so audio monitoring needs a workaround. That is a common complaint from video shooters.

The camera body, battery, USB cable and basic strap are standard. A memory card and a separate charger are not included, so plan for those.

Is the lens good for wide shots?

Yes. The 18mm equivalent wide end is wider than most compact vlogging cameras and suits arm's-length framing and tight indoor spaces.

Can it shoot in low light?

It can, thanks to the f/1.8 wide aperture, but the 1-inch sensor shows noise sooner than larger-sensor cameras. Expect usable results in dim rooms, not in near darkness.
