Canon 1D MIII vs Canon R5

On this page, we are comparing the Canon 1D MIII vs Canon R5, one is a Pro DSLR and the other is a Pro Mirrorless and both of them are produced by Canon. There is a huge difference among the sensor resolutions of the 1D MIII (10MP) and R5 (45MP) and the 1D MIII (APS-H) and R5 (Full frame) boast totally different sensor size.

The 1D MIII was introduced 14 years earlier than the R5 which is a fairly significant gap as far as camera tech is concerned. Both of these cameras have different body design with the Canon 1D MIII being a Large SLR camera and the Canon R5 being a SLR-style mirrorless camera.

Before we go into a in-depth comparison, here is a simple overview of how the 1D MIII grades versus the R5 in terms of portability, imaging, features and an overall mark.

The following is a sample of the gallery pics for Canon EOS-1D Mark III and Canon EOS R5. The whole galleries are viewable at Canon 1D MIII Gallery and Canon R5 Gallery.

For anybody who is going to travel with your camera frequently, you'll have to consider its weight and dimensions. The Canon 1D MIII comes with external dimensions of 156mm x 157mm x 80mm (6.1" x 6.2" x 3.1") having a weight of 1335 grams (2.94 lbs) and the Canon R5 has dimensions of 138mm x 98mm x 88mm (5.4" x 3.9" x 3.5") having a weight of 738 grams (1.63 lbs).

Take into account, the weight of an Interchangeable Lens Camera will vary depending on the lens you are using during that time. Here is a front view over all size comparison of the 1D MIII versus the R5.

Factoring in size and weight, the portability grade of the 1D MIII and R5 is 51 and 59 respectively.

In many cases, it's tough to visualise the contrast in sensor dimensions purely by researching technical specs. The pic here will provide you a better sense of the sensor dimensions in the 1D MIII and R5.

As you can tell, each of the cameras provide different resolutions and different sensor dimensions. The 1D MIII with its smaller sensor will make shooting shallower DOF more difficult and the Canon R5 will render extra detail using its extra 35MP. Greater resolution will make it easier to crop photos more aggressively. The more aged 1D MIII will be behind in sensor technology.
