Pentax WG-90 Blue waterproof compact camera

The Pentax WG-90 Blue is a rugged compact camera listed for underwater photography to 14 metres, with a 5× optical zoom and macro lighting. Its small fixed LCD and the listing’s inconsistent video and lens details are worth weighing against its outdoor-focused design.

Pros and cons

Pros

The stated ruggedness and dedicated underwater modes suit casual snorkelling and outdoor snapshots where a regular compact camera may be unsuitable.
Five-times optical zoom and macro lighting cover both wider scenes and close-up subjects without relying solely on digital zoom.
A macro stand is described as included and can help stabilise close-up shots on a flat surface.

Cons

The 2.7-inch display is fixed, limiting viewing flexibility when composing from awkward angles.
The listing describes manual focus as the focus type, so buyers seeking straightforward autofocus should confirm how focus works on this model.

What to know before buying

Listing details to confirm

The listing contains inconsistent technical details: it pairs 1080p video and H.264 Full HD claims with MPEG-4 as the stated video format, and gives differing lens focal-length descriptions, including 25 Millimeters maximum, 28 Millimeters minimum, 5-25mm and 5-25mm (35mm equivalent: 28mm-140mm) zoom lens with a telephoto range. The maximum aperture is also stated as 1.8 Millimetres, which is not clearly a standard aperture value. Confirm the exact specifications before buying. Waterproof depth and durability are manufacturer claims, not independently verified here.

Frequently asked questions

How deep is the Pentax WG-90 claimed to be waterproof?

The listing describes it as waterproof to 14 metres. Treat this as a manufacturer claim and follow the product’s operating guidance for underwater use.

Does the WG-90 have a macro feature?

Yes. The listing describes a Digital Microscope mode, six LED Macro Lights and a macro stand, with close focusing claimed from one centimetre.

Can the display tilt?

The display is listed as fixed, so it does not offer the viewing-angle adjustment of a flip or tilting screen.

What should I confirm about video and the lens?

The supplied details disagree on video format and lens specifications. The listing combines 1080p and H.264 claims with MPEG-4, and gives multiple focal-length descriptions, so confirm the exact configuration before buying.
