The small camera we recommend is the Insta360 GO 3S, a 39.1 g camera (its 96.3 g Action Pod carries the screen and second battery) that is the lightest camera on this page and still rated to 10 m, at $349.99 (64GB) or $379.99 (128GB) at Insta360's US store, checked 28 September 2026. The step up is the Insta360 GO Ultra, whose 52.9 g camera is 13.8 g heavier and costs $449.99 (checked 28 September 2026) for 4K60, a 1/1.28" sensor, PureVideo and 32 more minutes on the camera alone; DJI's 52 g Osmo Nano module sits between them on weight and is not officially sold in the USA.

This page ranks on one number: the published weight of the part that records. Every card then says what that weight costs in sensor size, frame rate, runtime and water rating. This site covers action, pocket and 360 cameras, not compact stills cameras, so none is ranked here and no compact-camera figure is quoted.

Three of the four picks are two-piece wearables: the camera goes on a cap or a shirt, and the pod or dock that holds the screen goes in a pocket. We give both weights and never add them together. Where a manufacturer publishes nothing, the tables say not published, and that includes blanks on both GO picks.

At a glance

The deciding column is the first: the published weight of the part that records. The DJI Osmo Pocket 3 and Insta360 Luna Ultra rows are for reference and are not ranked.

Runtime modes differ by maker: 1080p30 for the GO 3S, 1080p24 for the GO Ultra, Osmo Nano and Pocket 3, 8K30 for the X4 Air, and not stated for the Luna Ultra. The GO depth figures belong to the camera, which is IPX8; both Action Pods are IPX4 splashproof only. The X4 Air's Labor Day promotion has ended; the Osmo Nano's B&H price is a promotion.

What makes a small camera worth recommending

Stated before any pick, so you can check the ranking against it.

The floor. "Records properly" means at least 4K video and a published weight. Every camera on this page clears it, and a camera that publishes no weight cannot be ranked on a page ranked by weight.

Above the floor, six criteria, in this order:

1 · Published weight of the part that records — the camera module for a two-piece design, the whole body for a one-piece. This criterion alone sets the rank order, lightest first.

2 · Sensor size, the first thing a small camera gives up. Here it runs from the GO 3S's 1/2.3" to the GO Ultra's 1/1.28".

3 · Maximum video mode. 8K on a 360 camera is spread over the whole sphere, so it is not the same purchase as 4K on a flat camera.

4 · Runtime on the recording unit alone, because the pod or dock is exactly the piece you left in your pocket.

5 · Depth rating without a housing, quoted for the part that carries it, never for the kit.

6 · Price, dated, with the list-to-list gap wherever a promotion meets a list price.

highlight Criteria 2 to 6 do not reorder the list; they are what each pick gives up, and they decide the verdict.

Three auditing rules follow. The second piece is published beside the first and never summed, because no maker publishes a combined carried weight. A specification nobody publishes cannot be scored: Insta360 publishes no dynamic range and no screen brightness for either GO camera, and DJI's 13.5 stops for the Osmo Nano exists only in a press release, not in its spec table.

Insta360 is not clean here: the one screen-brightness figure among the four picks is DJI's.

A weight tolerance is part of the figure. Insta360 gives the GO Ultra's camera as 52.9 ± 0.5 g, so against the Nano's 52 g the gap is 0.9 g nominally and 0.4 g to 1.4 g across the tolerance. It never reverses. Why we score only what is published is on our how we test page.

Where DJI wins

Two DJI cameras beat Insta360 picks on published figures. The first beats our top pick on three of the five criteria after weight, and on the weight of its second piece too.

DJI's Osmo Nano beats the Insta360 GO 3S on sensor size, 1/1.3" against 1/2.3"; on frame rate, 4K60 against 4K30; on standalone runtime, 90 minutes against 38, or 52 minutes more; and on second-piece weight, a 72 g dock against a 96.3 g pod, 24.3 g lighter. It also publishes an 800-nit screen where Insta360 publishes no brightness for either GO camera, and a 45 °C ceiling against their 40 °C.

It also beats the GO Ultra on the ranking criterion itself: 52 g against 52.9 g, 0.9 g lighter, and still at least 0.4 g lighter across Insta360's ±0.5 g tolerance. Its dock is 36.5 g lighter, it runs 20 minutes longer on the module, and its slow motion reaches 4K120 against 1080p240. That is why it ranks above the GO Ultra.

Stated separately, afterwards: DJI does not officially sell the Osmo Nano in the USA, publishes no USD price for it, and rates module plus dock IPX4 only.

The DJI Osmo Pocket 3 needs no such caveat, because DJI lists it on its US store. It misses this list by 14 g, 179 g against the X4 Air's 165 g, and beats the X4 Air on three rows: sensor, 1" against 1/1.8"; slow motion, 4K120 where the X4 Air's single-lens ceiling is 4K60; and runtime, 166 minutes against 88, 78 minutes more, though in different modes (1080p24 against 8K30). It adds a 3-axis mechanical gimbal and a published 700-nit screen. The trades: no water rating at all, and a published operating range of 0 °C to 40 °C.

Insta360 takes the top slot on weight alone. It also holds the largest sensor among the wearables and the only recorded low-light mode (GO Ultra), built-in storage (GO 3S) and the deepest bare rating on this page (X4 Air) — not sensor size at #1, not standalone runtime, and not the lightest dock.

Buying guidance and what to skip

If you want a gimbal, buy the Pocket 3. The DJI Osmo Pocket 3 is 179 g, with a 1" sensor behind an f/2.0 lens, 4K60 video and 4K120 slow motion, for $439.00 at B&H (checked 28 September 2026). DJI's US store lists it at $439 but it is out of stock there, and B&H has it in stock; the Pocket 4 and 4P are not officially sold in the USA, so the Pocket 3 is the one to name. It is not rated for water, and DJI publishes 0 °C to 40 °C. The full case is in our DJI Osmo Pocket 3 review.

Skip the Insta360 Luna Ultra on this page. At 233 g it is the heaviest camera discussed here, 68 g over the X4 Air and 54 g over the Pocket 3. It has no waterproofing at all, and its "8K" is a marketing figure with no supporting specification. What it genuinely adds is a 60 mm telephoto beside a 20 mm main lens, 1×–12× zoom, 240 minutes, a 1000-nit OLED and 47 GB internal, for $769.99 at Insta360's US store (checked 28 September 2026), $330.99 more than the Pocket 3. Our Pocket 3 vs Luna Ultra comparison argues that trade in full.

Do not buy a two-piece camera on the box weight. The 39.1 g, 52 g and 52.9 g figures are cameras with no screen of their own. The screen lives on a 96.3 g, 72 g or 108.5 g second piece, every one of them IPX4 splashproof at best, so the 10 m figure belongs to the camera.

Storage is part of the price. The GO 3S ships with 64GB or 128GB built in; the GO Ultra has none and needs a microSD card, up to 2 TB.

Price honesty. Every price here was checked on 28 September 2026. The GO 3S, GO Ultra and X4 Air prices are Insta360's US store with no promotion running; the X4 Air's Labor Day promotion has ended. The Osmo Nano's $349.00 / $368.00 is a B&H promotion, so re-check before you buy. Where a promotional price is compared, the gap at the regular price is given too; for the Osmo Nano no list-to-list gap can be given, because DJI publishes no USD list.

Packing for a trip? Our best action camera for travel ranks what goes in the bag rather than the smallest thing that records, and orders these cameras differently for that reason.

Compact stills cameras are outside what this site covers, so none is named or measured here.
