Canon PowerShot D20 - Image QualityAs you’d expect from a Canon PowerShot compact, the D20 delivers a good level of image quality. Colours are generally true to life, with a pleasing level of vibrancy. The lens also performs well, with very little chromatic aberration noted, even in challenging lighting conditions.
The large buttons make using the D20 underwater particularly easy. The fast AF system helped, too, and exposures were good. Colours aren't as faithful underwater than on the very best on test, but the shots still look good.
Noise control at higher ISO settings is also generally good. The D20 delivers its best results between ISO 100 and 800, although above that point images do begin to soften and vibrancy also suffers.
Fujifilm FinePix XP60 - Image QualityAlthough most of the cameras on test coped admirably under water, the XP60 struggled most in this setting.
Images captured, even when utilising the model’s underwater setting, appeared much darker than the competition.
This may in some part be due to the disappointing performance of the camera at higher ISO settings. As soon as you get past even the second lowest ISO setting of ISO 200, shots begin to suffer from noise reduction loss of detail and sharpness, and muted colours.
Nikon Coolpix AW110 - Image QualityThe AW110 is another camera to benefit from the manufacturer’s above-water compact technology. The combination of Coolpix technologies mean that images are generally evenly exposed in a variety of conditions, while colours also display a natural palette.
Though our end result was decent, it took more shots to take a decent underwater shot on the AW110 than on rivals. You can't use the continuous shooting mode at the same time as the underwater mode, either, which is a tad limiting. Underwater colours and exposures are very faithful, though, and at 18 metres it goes three metres deeper than the next best.
The AW110’s lens also performs well, with images appearing crisp and clear straight out of the camera. The ISO performance is generally in keeping with the better performers of the group, maintaining detail and sharpness up to ISO 800. Above that, images do begin to suffer from noise reduction although that’s not unique to the AW110.
Olympus Tough TG-2 - Image QualityNot only does the Olympus TG-2 benefit from good all-round performance, including a rapid AF system, but image quality is equally impressive. It’s a real benefit to have the maximum aperture of f/2 at the wide-angle of the lens when it comes to shooting in low-light conditions, while even exposures are generally the order of the day.
The TG-2's mode dial was stiff and tricky to use underwater, but once set to the right mode the TG-2 is a joy to use underwater. Colours are rich and the exposure excellent.
The lens captures a pleasing level of sharpness. This sharpness does begin to fall off the higher you go through the ISO settings, namely above ISO 800, although this is more due to the high ISO noise reduction than anything to do with the camera’s lens.
Panasonic Lumix FT5 - Image QualityIf you’re looking for a reference point for the FT5’s image quality performance, it’s best that you look towards the Nikon Coolpix AW110 as it’s almost identical. Images straight out of the camera display a pleasing level of brightness, with a level of radiance surpasing any other in the test.
Underwater, the FT5's shots were comfortably the brightest of those on test, but lacked the richness of the Olympus or Nikon.
Outdoors, however, colours appear vibrant, while exposures are generally even. The FT5 is an admirable performer at higher ISO settings as well, rendering a good level of detail up to ISO 800. Beyond that detail does begin to suffer somewhat, although as mentioned previously that is par for the course with this group.
Pentax WG3 - Image QualityAlthough the Pentax WG3 has some excellent design features and handles particularly well, we can’t be as effusive about its photos.
Shots are disappointingly murky both above and below the water, pointing towards potential inconsistencies with the camera’s metering system.
It’s not all bad news however, as the WG3’s sensor resolves an impressive level of detail, in keeping with the best of the cameras on test. It also manages ISO noise well throughout the scale, although – like the rest of the cameras on test – it begins to fall off at ISO 800
