A modern phone camera is already good. Before spending anything, these four do more for the same money or less.
The four that beat a camera
1. Light. The biggest single improvement available. Daylight across the item, or one cheap lamp bounced off a white wall. A bad camera in good light beats a good camera in bad light every time. Camera and light
2. A stand. A steady frame reads as competence and frees both hands for the item. Costs almost nothing.
3. A plain background. A sheet of card. The item should be the only interesting thing on screen.
4. Stable upload. A beautiful picture that stutters is worse than an ordinary one that does not. Going live from a phone
If you have not done all four, a camera is not your bottleneck.
What a better camera actually buys
A closer, sharper macro shot — hallmarks, stitching, card surfaces. Genuinely useful for small detailed things.
Better performance in poor light, which matters if you cannot fix the light.
A second angle, if you can run two.
For most categories, none of that changes what sells.
If you still want one
A second phone is the cheapest external camera, and it already works — one on the item, one on you, or one as a producer's view. Using two devices while hosting
A clip-on macro lens is a few hundred rupees and does more for jewellery, coins and cards than a new camera would.
Check it can actually feed the browser. Metzee broadcasts from the browser, so a camera that only writes to a memory card is no use — it has to appear as a camera to the device you are broadcasting from.
Test it in a rehearsal before a real show. A setup that works in theory and not in practice is an hour you cannot get back. Can I practise before going live for real?
What buyers actually notice
That you showed them the thing properly — turned over, tilted to the light, held still while they looked.
Nobody has ever bought something because the sensor was larger. They buy because the flaw was shown and named. How to judge an item through a camera
The order to spend in
Light, stand, background, connection, then a lens, then a camera. Most stores never get past the first four, and they are right not to.
