Design and features
While it's not the flagship tough camera in the Olympus range — that's left to the TG-820 — the TG-320 is still designed to withstand the elements. The TG-320 is cased in a plastic exterior, which is rigid enough to survive some rough treatment, so it comes as some surprise to feel that the camera only weighs in at 155 grams.
Painted in a bright blue or red finish, the TG-310 is easy to see in all conditions, and it comes with a wrist strap in the box. The camera's rugged credentials read like so: waterproof to 3 metres, drop proof from 1.5 metres and freeze proof to -10 degrees Celsius. Elsewhere, the figures are a little less interesting, with a 3.6x optical zoom opening up to 28mm at its widest. The lens has a maximum aperture range of f/3.5-5.1. There's a 2.7-inch LCD screen at the rear, sporting a relatively low resolution of 230,000 dots.
It comes with a double-locking door to protect the SDXC card slot, battery and mini HDMI from being water damaged, although the rubber seal is rather small, compared to those we've seen on other rugged cameras.
On the topic of rubber, the rear buttons are coated in a rubber-like plastic, with a small instant-on recording button, a four-way directional pad and a zoom rocker all bedecked in this outfit. There's a small speaker also located at the back.
Along with the regular intelligent automatic mode, the camera comes with a range of scene modes, panorama mode, 3D mode and program auto-recording. The TG-310 also has magic filters, which is the Olympus terminology (in its compact range at least) for artistic filters, such as pop art, fish eye and soft focus. There are eight magic filters all up, and, rather confusingly, the camera limits the output resolution to 5 megapixels when shooting with them.
Anyone wanting to create underwater cinematic masterpieces will be a tad disappointed, with only 720p HD video recording on board. The TG-320 comes with in-camera battery charging, through a particularly long cord that is constructed from the proprietary USB cable, the power adapter and the power cord.

The TG-320 has a high-speed sequential-shooting mode that reduces the resolution to 3 megapixels and takes 3.5 frames per second. Note that the performance comparison is against two older models (Panasonic, Sony) rather than the newer models in the comparison table above. We'll update this review once we've tested the newer models.
The TG-320 delivers images that are fine for a camera of this class, particularly for sharing online at reduced resolutions. Photos at 100 per cent magnification look over-processed and slightly crunchy, a trait that we have seen on other tough cameras before. When shooting in automatic mode, colours are slightly muted and not as saturated as they could be. There are, of course, artistic filters to augment the colours, should you desire. The TG-320 is at its best when underwater, as it delivers punchy blue tones. The screen is also relatively easy to see underwater.
