5 Smaller Underwater Camera Housing Systems to Compare
A smaller housing body can make travel easier, but the camera lens, port and lights determine the finished size. These five options range from a compact TG camera to smaller interchangeable-lens systems. They fit different cameras, so use this list while planning a system rather than shopping for a substitute enclosure for an existing body.
Updated · Manufacturer specifications and published review evidence
How we chose and ordered these picks
The compact-camera option leads, followed by small-system housings and a fixed-lens-port arrangement. No carry-on guarantee is implied.
List position is an editorial recommendation, not a review score. The selection uses the documented features and limitations below. We have not personally tested this equipment. Verified publisher scores, where available, are shown separately and link to their evidence. Our catalogue is still being researched; inclusion does not mean a product has a completed scored review.

The TG-PRO is an aluminium camera housing sold for Olympus/OM System TG-6 and TG-7 cameras. Its appeal is the built-in electronic vacuum system, access to camera controls and provision for an internal 18650 battery to charge the camera. The 52 mm port thread accepts compatible wet optics; 67 mm lenses require an adapter.

What to check
Kraken’s description says 100 m, while its specification table and housing photograph say 80 m. Treat the depth rating as unresolved and obtain confirmation for the actual housing before purchase. The page also mentions TG-5 compatibility, which should be checked rather than inferred from the TG6/TG7 title.

The NA-OM5II is a compact N85 housing for the OM SYSTEM OM-5II. Its 1.3 kg housing weight offers a relatively small starting point for a Micro Four Thirds rig, with the final size determined by the lens port and lighting.

Optional M14 25624
What to check
A tray and handles are optional. The Olympus mini flash trigger requires a specified serial number, while several accessory entries on the manufacturer page are still provisional. Reviews of the older E-M5 II housing do not apply to this model.

The NA-A7CII/R houses either the Sony A7CII or A7CR in a relatively compact N100 body. At a listed 1.9 kg, it is lighter than several larger Sony Nauticam housings, though a finished underwater setup still needs its lens port and lighting. It is intended for owners who want to keep one of these compact full-frame cameras underwater.

From S/N A599661; extra bulkhead/adaptor required
What to check
An optical LED trigger or electrical bulkhead is optional rather than included. Vacuum monitoring also needs the separate valve to perform a vacuum check. Surface USB-PD bulkhead compatibility applies from serial A599661 onward, with the specified additional parts; confirm the serial of older stock or a used housing. The listed monitor options use HDMI 1.4.

The NA-XT5 is Nauticam’s dedicated Fujifilm X-T5 housing, built around an N100 port mount and a two-handle frame. It suits an X-T5 photographer who wants interchangeable underwater optics and external strobes while retaining that camera system. Leak-monitoring electronics and the grip mounting balls are supplied with the housing.

What to check
Ports and gears are separate, and the N100 mount should not be confused with N85 housings used for other smaller cameras. The flash trigger and M14 vacuum valve are optional. Nauticam lists made-to-order availability, so confirm delivery and return conditions. HDMI accessory compatibility includes a serial-dependent note that should be checked against the actual unit before purchasing cables.

The NA-Z50II takes a deliberately restricted approach: its fixed flat port is designed for Nikon’s Z DX 16–50 mm f/3.5–6.3 VR lens. A preinstalled bayonet supports compatible wet optics, giving the travelling photographer options without a conventional interchangeable dry-port system.

What to check
The fixed port limits lens choice. The camera’s pop-up flash provides optical triggering, and the vacuum valve is extra. A published Z50 II camera test used an Ikelite housing, so it cannot establish a Nauticam housing score.

Before you buy
Measure and weigh the complete rig including its port.
Check which controls remain available with the selected camera.
Read lens restrictions carefully on fixed-port housings.
Take two or three suitable models from this list into a comparison, then remove any that fail your fit or compatibility checks. A lower position here can still be the better purchase for your setup. Check the product page for source dates and unresolved details before placing an order.
Are all lenses for the camera supported underwater?
No. Housing and port support is lens-specific. The NA-Z50II entry, for example, uses a restricted fixed-port lens arrangement that must be checked before buying.
