The Surface

cmos

It is Canon's CMOS technology that gives the EOS 5D Mark II and EOS 50D their quality, speed and high ISO performance edge. Large pixel sites (4.7 pm2 on the EOS 50D and 6.4 pm2 on the EOS 5D Mark II) maximise photo diode area while minimising microlens gap, to provide exceptional dynamic range and sensitivity. Canon's CMOS refreshes quickly, for faster frame rates, and runs cooler to help reduce noise and extend battery life. And when light is fading, expanding to ISO 12,800 on the EOS 50D and ISO 25,600 on the EOS 5D Mark II will keep you shooting at fast shutter speeds without the need to switch to flash.

digic 4

To handle the sheer volume of data generated by the EOS 5D Mark II and EOS 50D, Canon's engineers have developed DIGIC 4: Canon's new generation image processor. DIGIC 4 delivers the power to process 14-bit sensor data, for smoother tonal gradations, faster than ever before. As well as being fast, processing delivers precise colour reproduction. DIGIC 4's high ISO noise reduction algorithm with new level settings strikes the perfect balance between preservation of detail and the removal of unwanted static. Peripheral Illumination Correction is now available in camera, while a Highlight Tone Priority feature retains detail in bright areas. And naturally, DIGIC 4 delivers the fast playback, long battery life and fast start-up times for which digital EOS is renowned.

eos integrated cleaning system

To keep your images pristine, the EOS 5D Mark II and EOS 50D do more than just vibrate the sensor to loosen unwanted dust particles. An integrated system of components and materials that works in concert to reduce, repel and remove dust now includes a Fluorine coating on the cameras' low-pass filter, substantially increasing the resistance to dust adhesion. The effect of any resistant particles recorded as Dust Delete Data can be removed automatically with Canon's Digital Photo Professional software.

The soft-touch release shutter mechanism on both cameras has a maximum speed of 1/8,000 second, with a durability rating of over 100,000 cycles. The whisper-quiet mirror mechanism is dampened in both directions to minimise unwanted vibrations. For particularly sensitive situations, an electronic 1st curtain shutter mimics the high speed mechanical shutter for virtually silent operation.
