j'ai fait de la photo à 30m en Bretagne avec un compact (nikon coolpix 885, pas une bete de course), sans flash externe, et de très jolis photos a la clé, la preuve est là  ;)

Ah oui, mais c'est triché, c'est au flash 

ben voui, la preuve que le flash integré sur un compact, dans une eau réputée chargée, n'est, finalement, pas à oublier ;)

J'ai déjà testé à ces profondeurs dans le léman, ça fait un beau portrait de particules en suspensions 

ben d'un autre coté, dans un lac de montagne, quoi attendre d'autre que de la neige? 

Le site dpreview.com a publié un test d'appareils waterproof 



• Canon PowerShot D10 •
• Fuji FinePix Z33WP •
• Olympus Stylus Tough 6000 •
• Olympus Stylus Tough 8000 •
• Pentax Optio W60 • 1/2.33" CCD •



Le Pentax W60 se classe 2e (tout proche du 1er) et est un choix recommandé

The Pentax W60 is certainly an attractive package, and with a 5x zoom lens that extends from 28mm to 140mm HD video capture, you would think that it would make a great competitor to the D10 for winner of the group test. But looking closer you find that the 720p video is only recorded at 15 fps, and to get 30 fps you have to step down to VGA resolution. The lack of built-in image stabilization means that the W60 needs to use higher ISO setting to reduce camera shake compared to the D10.

Looking closer at the image quality, especially at lower ISO settings, the D10 constantly produces sharper more detailed results than the W60, and with no control over sharpening or noise reduction, you are pretty much stuck with the output of the camera as it stands. The flash performance is also not as good at the D10, and the very poor red eye performance with flash is especially concerning. As a underwater camera the W60 can only be used to 3m / 10ft, which is far off the 10m / 33ft of the D10, and the interface of the W60 is harder to use while in the water than the D10. Ultimately if you are going to mainly use the camera out of the water, and need something that can fit easily in your pocket then the W60 is certainly worth a closer look.
