Comparisons with Canon's own cameras are even more stark. The EOS 5D Mark III was previously Canon's highest resolution DSLR, with 22 million pixels – but the 5DS more than doubles this at a stroke. Pixel area difference: 32.21 µm² (83%) A pixel on Nikon D3 sensor is approx. 83% bigger than a pixel on Canon 5D Mark III. Pixel density. 1.41 MP/cm². 2.58 MP/cm². Difference: 1.17 µm (83%) Canon 5D Mark III has approx. 83% higher pixel density than Nikon D3. To learn about the accuracy of these numbers, click here. The 5D Mark III offers a respectable 22.3-megapixel resolution and very solid low-light performance for its time. It also includes a wide selection of autofocus customizations, so you can tweak its performance much like you can with the newer 5D Mark IV or 1D X models. The Canon EOS 5D Mark III is built around a new 22.3 megapixel full-frame, self-cleaning CMOS sensor and promises high performance and claims improved noise reduction at higher ISOs with its DIGIC 5+ sensor and up to 6 frames per second burst rate in RAW and JPEG. If you’re a Canon lover, don’t despair. Canon, of course, has its high-resolution DSLR equivalent and that’s the Canon 5D Mark IV. It’s not as high in megapixels as the rest of the cameras on this list, but it turns out impressively sharp images with exceptionally high-quality color output. The Canon 5D Mark IV comes with a high-speed Canon EOS 5D Mark III; Overview; Type: Digital single-lens reflex camera: Released: March 2012: Intro price: US$ 3499.00: Lens; Lens: Interchangeable : Sensor/medium; Sensor type: CMOS: Sensor size: 36 × 24 mm : Maximum resolution: 5760 × 3840 (22.3 effective megapixels) Film speed DxO Labs has tested 85 lenses on the Canon EOS 5D Mark III and analysed the results, looking at its two proprietary measures: 'Perceptual Megapixels' for lens sharpness, and the overall DxOMark score. In the first section of a multi-part series, it makes comparisons against both the EOS 5D Mark II and the Nikon D800, with results that may be surprising.
