First time DSLR users are the target for a new 12.4-million-pixel digital SLR from Pentax called the K-x, featuring ‘HD’ video and a top equivalent ISO expandable up to 12,800.
Though not designed to replace any other camera, Pentax UK has confirmed that the K-m – announced earlier this year – has been discontinued.
Featuring the same chassis as the K-m, the camera appears to take its name from the ‘Pentax KX’, a 35mm film SLR camera launched by the firm way back in 1975.
In a nod to the days of film, Pentax has installed a mode designed to simulate the effect of ‘cross-processing’, to create ‘eye-catching’ images. This function includes three preset options, plus the ability to set these randomly, according to Pentax UK.
Billed as an ‘entry class’ camera, the K-x DSLR houses a new CMOS imaging sensor and the same Prime II imaging processor as its higher end sibling, the 14.6MP K-7. This aims to boost AF speed and accuracy in low light.
The Pentax K-x will go on sale at the end of October, priced around £600, in a choice of black, white, blue and red. It will be available as a kit with an 18-55mm lens. We understand that the K-x will not go on sale body only.
The Live View-enabled model includes Face Detection to automatically detect up to 16 faces. The camera uses Contrast AF, and Phase Detection AF.
Like the K7, the K-x includes digital filter effects such as Star Burst and Fish Eye.
Image stabilisation comes in the form of a sensor-shift mechanism.
Photographers can shoot at a rate of up to 4.7 frames per second for up to 17 JPEG files and five raw format frames, says Pentax.
Also on board is a ‘dust-removal’ mechanism.
The ‘Pentax-only’ developed model weighs 515g and sports a 2.7in LCD screen carrying a resolution of 230,000 pixels.
The Pentamirror-equipped camera features 16-segment metering and an 11-point SAFOX VIII AF system (featuring nine cross-type sensors). The viewfinder is claimed to offer a field of view of 96%.
The K-x incorporates a built-in High Dynamic Range (HDR) function designed to create one composite image – with ‘extra-wide dynamic range’ – from three different exposures.
Boasting a top shutter speed of 1/6000sec the K-x aims to deliver 1280×720 pixel (24 frames per second) videos.
Though there is a built-in microphone, there is no option to add an external microphone.
The K-x will be launched alongside a new lens. The Pentax-DA L 55-300mm f/4-5.8 ED is described as a ‘lightweight super-telephoto’ that delivers the 35mm viewing angle equivalent of a 84.5-460mm lens.
The zoom will be available as part of a twin-lens kit (which includes the 18-55mm lens), priced £749.99.
