The low-pass filter at the front of the sensor shakes off dust automatically with ultrasonic vibrations. To combat against this, the EOS 5D Mark II features a Canon-designed Self Cleaning Sensor Unit. Dust that makes it past the EOS 5D Mark II's sensor cleaning system is easily removed in post processing using DPP software's Dust Detection Delete function, which can remove dust spots automatically from single or multiple image files.Ī key element of minimizing dust is preventing it from clinging to the front surface of the imaging sensor. The camera's low-pass filter even has a new fluorine coating upon its surface to help repel dust. Lens Peripheral Illumination Setting ScreenĬanon's Integrated Cleaning system includes a cleaning unit designed specifically for the EOS 5D Mark II's full-frame CMOS sensor. Correction data are detected automatically on a number of Canon lenses and can be entered manually through included Canon EOS Utility software. Sophisticated processing algorithms help to speed up all operations, including write times to UDMA cards.Ĭanon's exclusive Lens Peripheral Illumination Correction takes into account any light falloff in the corners of the frame and corrects it, making for a perfectly exposed image. The analog output from the image sensor is converted into a digital signal via 14-bit conversion instead of the previously used 12-bit conversion, resulting in significantly finer tonal gradation for better prints.ĭeveloped to maximize performance between capturing and recording stages of digital photography, Canon's DIGIC 4 chips use advanced signal processing technologies to enhance captures from Canon's CMOS sensors.

The EOS 5D Mark II also offers full 14-bit A/D conversion. Processor intensive operations like Face Detection Live mode, HD video recording and lighting and lens peripheral optimization are all possible thanks to the DIGIC 4 Image Processor. The EOS 5D Mark II's sensor is backed up by Canon's DIGIC 4 Image Processor, which speeds up all operations making a number of new features possible.
