Waterproof camera Pentax Optio W20
The W10 was one of the first truly waterproof cameras. Previously if you wanted to take your camera underwater you would need a bulky and hard-to-use watertight case but the W series changed that. The Pentax W20 is the latest generation of the W series and the W20 adds more features and performance.
The W20 has a waterproof casing but this doesn’t mean you can take the camera to the depths of the ocean because there are limitations due to pressure. Being a waterproof camera it’s based on the cameras size, which is pretty standard.
One major issue with image quality is vignetting. This is a darkening of the corners of the image and is sometimes found on super wide lenses.
The camera is pretty fast, turning on almost as soon as you release the on/off button.
The W20 has a big selling point in its ability to be waterproof without being bulky, allowing it to be a perfect travel camera for all occasions, in water or out. It has a sensor that can perform when needed and enough options to satisfy every level of ability. The camera isn’t without its faults, and these may hold it back compared to other compacts, but against similar waterproof cameras, it’s well worth a look.
