The Pentax Optio WG-3 is a waterproof, dustproof and shock-resistant compact camera which can be used at a depth of up to 14 meters and can withstand a drop of 2 meters, cold to -10°C and a weight up to 100kg.
Features include a stabilized 16MP CMOS sensor, and a relatively fast F2.0-4.9 lens with 25-100mm equivalent zoom. This camera has versatile zoom lens accommodates a wide range of applications - from macro shooting of flowers to wide-angle shooting of spectacular landscapes.

The Optio WG-3 also equipped with image-sensor-shift-type Shake Reduction, a 3 inch 16:9 ratio LCD monitor with 460K dots, and six built-in LED macro lights.With anti-shake feature, then you can maximize the zoom lens on this camera.
The camera’s Intelligent Zoom function also extends the zoom range to approximately 28.8 times to cover the focal length of an approximately 720mm super-telephoto lens to capture extra-high-magnification images without compromising image quality.
The Pentax WG-3 is the less expensive version of the Optio WG-3 GPS, and while it omits the wireless charging and GPS (obviously) features of its costlier cousin it still offers a strong feature set for an affordable price. This camera delivers reliably good image quality and decent video, making it attractive as a 'knockabout' camera or a tough compact for travelling and everyday use. Like many everything-proof cameras these days, the WG-3 features a rubbery grip and rugged design.

The Pentax Optio WG-3 has Sharp lens with Wide aperture and Short shutter lag plus Macro LED lighting and you can enjoy a very unique design. The WG-3 features a bold design that combines bright, metallic colors with a body style that's a bit wider than most compact cameras.
The WG-3 features Full HD movie recording, a 16 megapixel back-illuminated CMOS sensor, a 4x optical zoom lens with 25mm wide-angle coverage and a maximum aperture of f/2. The newly designed optical zoom lens offers a maximum aperture of F2.0 to capture bright, clear images with minimal noise, even under dimly lit underwater conditions
The WG-3 is one of the more interestingly designed tough cameras on the market. Its lens is fast and sharp. The closest competitor of the Pentax Optio WG-3 is Olympus TG-2 and the Canon PowerShot D20. You can compare them before you decide to buy one of them. Due in February 2014 is still in the atmosphere of Chinese New Year, then you have a chance to get the special discounts, there is even a possibility to get additional accessories or a memory card in a larger capacity, for example, a 16GB memory card, so you can shoot more without dizziness due to runs out of memory.

Although the Sigma camera are not as famous as Sony or Olympus cameras, but you certainly will be amazed with this new camera, the Sigma DP2 Quattro and other Quattro series.
By making the Sigma DP Quattro, perhaps Sigma wants to solidify its image in the world of photography, then in addition to successfully create various types of lenses, the Sigma also able to make digital cameras such as Panasonic, Pentax or Samsung. Sigma DP series is launch 3 series; The DP Quattro series will Consist of three models: the DP1 with a 28mm fixed focal length, 45mm at DP2 , and DP3 at 75mm (35mm equivalent all ).
All lenses have an aperture range of f/2.8-16, DP1 and DP2 with the having a nine - blade diaphragm and a seven - blade diaphragm in the DP3. Lens construction is nine elements in eight groups (DP1), eight elements in six groups (DP2), and 10 elements in eight groups (DP3).
The lens specifications, in terms of numbers of groups and elements, and minimum focusing distances, remain unchanged from the 'Merrill' models. All three models will have 920k dot rear LCDs and 9-point contrast-detection autofocus systems. You can enjoy improved optics, ISO performance, image processing and design.
Works of art camera
The Sigma DP Quattro is redesigned in every aspect, including the sensor, engine, lens and body, the DP Quattro Compact Camera series embodies Sigma’s philosophy of creating cameras that produce works of art. If you look the specification, then the cameras are similar to the Sigma Merrills, - fixed 19mm, 30mm, and 50mm f/2.8 lenses paired with Sigma’s unique Foveon APS- C sensor - but the industrial design is a radical departure from anything else on the market. The Sigma DP2 Quattro is the next generation of its DP series of APS-C sensor, fixed focal length cameras. The latest, 45mm-equivalent, model features dramatic styling and a fundamental re-think of the company's Foveon multi-layer sensor design.
Sigma has always released its compacts in trios: same camera, different prime lenses. The 1st of the three new Quattro cameras will be released with a 20 MP Foveon X3 sensor, the new faster True III processor and a 30 f/2.8 lens attached. Sigma has also made a leap to a faster TRUE III image processor. There is another surprise that you will find, there's also an opticalviewfinder available for purists, which should work well with the fixed lenses. The DP2 Quattro will come with a 30mm f/2.8 general purpose lens, while the DP3 and DP1 will respectively carry 19mm wide-angle and 50mm telephotooptics. The image quality that Foveon chips output is incredibly detailed. The new Foveon X3 Quattro offers an even higher level of image purity with a 30% increase in resolution to the previous Foveon sensor, sure to bring about new experiences in your photography.
If you look at the shape of this camera, very different from the previous Sigma cameras, even appears in contrast to the compact-system camera ever you known, with a very unusual shape. You could also say that this form of the Sigma DP Quattro has almost cinematic body shape is meant to provide a more balanced feel in the hand than the compact design of its predecessors. The camera has a wide, relatively thin body with a grip that bends backwards at about a 45-degree angle.

The camera is made by Sigma is different from other cameras, Sigma's cameras use a technology called Foveon. This special sensor has three layers, with each layer sensitive to blue, red or green. This way the camera has color information from all three channels at every point in the frame. The result is generally a very sharp, very large image. Autofocus is greatly improved, continuous shooting times are a little more usable, and the battery life has more than doubled. The Quattro models will also see vastly improved battery life when compared to previous DP-series compacts.
If you are interested in the sophistication of the camera sensor and lens on the Sigma DP Quattro, then what series would you choose out of the three?
