Canon 1D Mark IV vs 1D X Mark III Overview and Optics

The Canon EOS 1D X Mark III outperforms the Canon EOS 1D Mark IV in optics, with a score of 74/100 compared to the Mark IV’s 54/100. Both cameras share several specifications, such as the CMOS sensor type, Canon EF lens mount, and the absence of image stabilization.

The 1D X Mark III excels in multiple aspects. Firstly, it boasts a higher megapixel count of 20.1 compared to the 16.1 megapixels of the 1D Mark IV. This allows for larger and more detailed images. Additionally, the 1D X Mark III has a faster shooting speed of 20 frames per second, doubling the 10 frames per second of the 1D Mark IV. This enables capturing fast-moving subjects more effectively. Furthermore, the 1D X Mark III has a superior sensor, as evidenced by its DXOMARK score of 91, compared to the 1D Mark IV’s score of 74. This results in better image quality and low-light performance. Lastly, the 1D X Mark III’s full-frame sensor size provides a broader field of view and improved image quality compared to the 1D Mark IV’s APS-H sensor size.

Despite its lower score, the 1D Mark IV has a noteworthy advantage in being equipped with the Digic 4 processor, which is known for its reliability and consistent performance. However, the 1D X Mark III features the newer and more powerful Digic X processor, providing faster processing and improved performance.

Taking all factors into consideration, the Canon EOS 1D X Mark III’s superior optics make it the better choice for photographers seeking higher image quality, faster shooting speeds, and better low-light performance. The Canon EOS 1D Mark IV remains a reliable option but falls short in comparison to the 1D X Mark III’s advancements.
