Sigma DP1s is an improved version of the Sigma DP1, and both cameras contain a the same processor, 14-megapixel FOVEON X3 direct image sensor and lens with a focal length of 16.6mm F4 (35mm equivalent focal length is 28mm).
The new Sigma DP1s features enhancements to its user interface that mimic that of the DP2 and will provide photographers with improved user capabilities.
Sigma DP1x remains true to that objective and maintains its wide focal length lens, but reflects several upgrades from the initial introduction of the DP series back in 2008. Specifically, it now houses the "True II" image processing engine, the new AF algorithm provides high speed auto focusing, ensuring convenient shooting and the Power Save Mode lowers the battery consumption allowing for a greater number of pictures to be taken with a single battery charge. The new rear design makes the user interface easier to interpret and use with quick, easy button recognition as the addition of red buttons enables easier operation of the camera controls.
Sigma DP2s is a high-end compact digital camera equipped with a 14 megapixel (2652 x 1768 x 3 layers), Foveon X3 direct image sensor. Featuring Sigma's unique True II image processing engine and a 24.2mm f/2.8 lens, this compact camera provides the same superb image quality as found in the Sigma SD14 professional SLR.
The Sigma DP2x is the latest DP2 series model and incorporates AFE (Analog Front End) and high speed auto focus. AFE is used to converts full color data, which the FOVEON X3 capture system records, into a digital signal. This enables the camera to reproduce high definition and richly colored images. In addition, the new AF algorithm provides high speed auto focus, ensuring convenient shooting.
Pentax K-7 brings together a wide range of advanced functions and user-friendly features with outstanding reliability and operability. The 14.6 megapixel CMOS sensor, 11-point wide-frame AF and 77-segment metering systems assure superior resolution and exposure control. Fast 5.2 frame-per-second shooting and top shutter speed of 1/8000 second ensure you capture all the action with ease while Live View and HD movie capture enhance your shooting experience. One of the smallest bodies in its class, the K-7's durable magnesium alloy body with a rugged stainless steel chassis and full weather resistant, dustproof and coldproof design makes it the ideal choice for shooting in almost any environment, indoors or out.
The Pentax K-5 inherits the exceptional reliability, user-friendly operation, array of advanced features and compact, lightweight body of its predecessor, the highly acclaimed K-7, yet is more resourceful and flexible in photographic expression. The K-5 features a new 16.28 megapixel sensor, and has a wide sensitivity range from ISO 80 to 51200 (when expanded via a custom function). With a much faster autofocusing speed, an upgraded HDR (High Dynamic Range) function that is now usable in handheld shooting and full HD movie recording at 1920 x 1080 pixels, the K-5 is designed to be more functional and maneuverable in every detail, and more capable of responding to the discriminating demands of advanced photographers.
The Pentax K-x combines solid photographic performance with a wide array of advanced features at an affordable price. It features PENTAX's innovative in-body Shake Reduction mechanism for sharper blur-free images, 12.4 megapixel CMOS sensor, comprehensive Dust Removal system, HD movie capture and high-speed continuous shooting of approximately 4.7 frames per second in its ultra-compact body. These features, along with the user-friendly PENTAX-original Auto Picture mode and Live View with a choice of three different focusing modes assure great results every time.
The multi-featured Pentax K-r digital SLR camera features simple operation and a host of creative tools in a compact, lightweight body that is exceptionally comfortable to use and is easy to carry anywhere.
