Kodak sensor in Leica M8

Sep 15, 2006 at 23:07 GMT

Kodak today issued a press release stating that the new Leica M8 features their new KAF-10500 CCD. This was developed specifically for the M8 with offset microlenses to help reduce the effect of vignetting due to severely off-perpendicular light towards the corners of the frame (especially when using wide angle lenses). The KAF-10500 has an active area of 27 x 18 mm, a 6.8 µm pixel pitch and two channel output.

New Kodak Image Sensor Powers LEICA M8 Digital Camera

Rochester, NY, September 15, 2006 – Eastman Kodak Company is extending its partnership with Leica Camera AG to provide image sensors for the newly announced LEICA M8.  The new KODAK KAF-10500 image sensor was developed specifically for use with the M8, and marks Kodak’s second collaboration with Leica, building on the success of Kodak’s interaction with Leica on the LEICA DIGITAL-MODULE-R.

The first digital camera to use the Leica viewfinder system, the LEICA M8 extends the Leica M series into the digital world.  By working closely with Leica, Kodak designed and optimized the new image sensor to meet the demanding needs of Leica photographers.

With a resolution of over 10 million pixels, the KAF-10500 continues Kodak’s legacy of offering high performance imaging devices that leverage Kodak’s Indium Tin Oxide (ITO) technology for low noise, high sensitivity, and wide dynamic range.  Utilizing a 6.8µm pixel architecture, the sensor uses an optimized microlens configuration to maximize center to corner uniformity for improved image quality, particularly important for the broad incident light angles associated with M series lenses.  The sensor also includes anti-blooming protection to prevent against image corruption during high light level conditions.

“We are excited to be broadening our relationship with Leica by supplying sensors for the M8 digital camera – the newest member of the Leica M system,” said Chris McNiffe, General Manager of Kodak’s Image Sensor Solutions group.  “Kodak will continue to work with camera manufacturers such as Leica to provide industry leading imaging technology that meets the evolving demands of today’s photographers -- from professionals who demand the highest in resolution and performance, to consumers looking for advanced imaging devices such as digital still cameras and camera phones.”

Kodak delivers the core technology that drives the most advanced developments in digital imaging applications.  A pioneer in image sensing, Kodak develops, manufactures, and markets both CCD and CMOS image sensors for applications ranging from satellite and medical imaging applications to digital cameras and machine vision products.
