![]() ![]() ![]() The AF system is sensitive down to -3EV (-4EV in Live View) – that's darker than moonlight Impressive though this is, this expanded range is actually identical to the 5D Mark III's, although Canon reckons it has enhanced the noise-processing algorithm for improved results at higher sensitivities, while it's also a stop more than one of this camera's closest competitors, the Nikon D810. The native sensitivity runs from ISO100-32,000, and is expandable to 50-102,400. You can then open the file in Canon's Digital Photo Professional software, and use Image Micro-adjustment to shift the focus ever so slightly not massively, but Canon believes there's the potential to rescue some shots using this technology.Īs you'd expect, the file size increases dramatically, from 37MB to 67MB – and you will have to use Canon's rather clunky DPP software. With each pixel made up of two photodiodes, it allows for the creation of a file which contains a pair of images with two very slightly different focus points. That's not the whole story as far as image quality goes though, with the arrival of Dual Pixel Raw technology giving photographers the capacity to fine-tune the area of maximum sharpness.
