Upcoming Canon 80D or 7D Mark III to feature built in ND filter

canonToday we come with the latest information that Canon filed patent to increase dynamic range by using a Neutral Density (ND) filter on half of the measured field, which is a very complex mode.

The function of the system is described by the image and it mentioned that the system starts processing when different degrees of light intensity from the Dual Pixel auto-focus (DPAF) split the pixels on the sensor. According to the patent, the ND filter will be placed on half of the measured field and when the light hit the sensor with the help of new latest technology the sensor will automatically measure the exposure value of the scene with increased dynamic range.

 

  • Patent Publication No. 2015-87401
  • Published 2015.5.7
  • Filing date 2013.10.28
  • Canon patents
  • Dual Pixel AF
  • And set up a half-ND filter at the pupil position of the lens
  • Half ND filter can be switched

Where Canon will use its latest technology ? – Only the Canon XD (7D Mk II) and XXD (70D) series today are enjoying the Dual-Pixel CMOS AF sensor and we do believe that Canon will bring out this tech ASAP to increase the dynamic range of the DPAF sensor since Canon DSLRs right now have the lowest dynamic range in industry compared to its competitors as we can see in the test results published by the DXO Mark Lab.sony-a77-dxo-lab-image2
