The more expensive models in the Tough range look like they are really well built to survive extreme conditions, with the TG-320 being much lighter and feels more like a typical compact camera. It has a plastic body with a solid clip to hold the battery and memory card cover firmly in place. The TG-320 lacks the chunky OK button, used for changing the camera setting, with a standard d-pad instead. There is also a metal plate which helps grip and is also used to attach a strap and the playback button allows viewing of your pictures and videos even when the camera is switched off. The rear of the camera also hosts a 2.7 inch, 230,000 dot LCD screens which is easy to view in all lighting conditions. Olympus haven't provided a CIPA rating for the camera's battery but it was charged before testing and was not needed to be recharged Olympus Battery Charger. We tested the camera's performance at focusing, shutter response, shot-to-shot time, continuous shooting etc. and have posted the results below. To test this we took 6 or more shots and calculated the average.
The Olympus Tough TG-320 produces images which are really well exposed with very pleasing color reproduction. Detail is good at both ends of the lens, soft in the corners and with some purple fringing in high contrast areas. In super macro mode the camera has a minimum focusing distance of 2cm, allowing decent close-up shots to be taken. Noise is minimal at the two lowest settings of ISO 80 and 100, with noise increasing steadily at ISO 200 and 400. Noise causes images to become soft at ISO 800, with ISO 1600 producing images with lots of noise, not ideal for large prints, but color reproductions is still good, even at the higher ISO settings.
The auto white-balance setting takes an image with an orange cast under the incandescent lighting, with the respective preset taking a better picture. Under the fluorescent lighting, the AWB setting has a very slight magenta cast, with the fluorescent preset giving a much stronger magenta cast.
The TG-320 Olympus TOUGH Charger can withstand drops from five feet in the air, temperatures as low as 14 degrees Fahrenheit, dusty environments that would normally harm electronics, and water submersion down to 10 feet.
