Canon R3 Vs Canon EOS 5D IV

The Canon R3 and the Canon EOS 5D IV are both strong cameras produced by Canon, and this article will provide a comprehensive analysis comparing the two of these models. These cameras satisfy a variety of requirements and inclinations, but they all possess outstanding qualities that set them apart in the competitive market.

If you are wanting to update your gear as a photographer, whether you are a professional or an amateur, it is important that you be aware of the differences and similarities between these two models. This will allow you to make a more educated choice.

Overview of Canon R3 and Canon EOS 5D IV

First, before we get into the specifics of the features, let’s take a high-level look at the two different cameras. While the Canon EOS 5D IV is a highly rated single-lens reflex camera, the Canon R3 is a high-end mirrorless model from Canon.

The R3 is one of the most cutting-edge mirrorless cameras available on the market due to the cutting-edge technology that it possesses. On the other hand, the EOS 5D IV is a workhorse digital single-lens reflex camera that has gained a reputation for its durability as well as its image quality.

Design and Build

The Canon R3 flaunts a streamlined and contemporary appearance in terms of its overall design. It is constructed with a body made of magnesium alloy, which provides durability without sacrificing lightweight portability. The construction of the camera is weather-sealed, which protects it from dust and moisture. This is an important feature for photographers who work in outside environments.

A magnesium alloy frame is used in the construction of the Canon EOS 5D IV, which, due to the fact that it is a DSLR, is a little more cumbersome camera. Its time-honored design has been honed to perfection over the years, making it easy to hold and control even during lengthy hours of shooting.

Image Sensor and Resolution

The Canon R3 features a stacked CMOS sensor with a full frame resolution of 24.1 megapixels, which was recently created. Because of the architecture of the sensor, quicker data readout is possible, which ultimately results in less rolling shutter distortion and improved image quality. In addition, the camera has an ISO range that can be expanded to a maximum of 204,800, allowing for exceptional performance even in low-light settings. This range is between 100 and 102,400.

On the other hand, the Canon EOS 5D IV is equipped with a full-frame CMOS sensor that has 30,4 megapixels, which results in photographs with an amazing resolution and level of detail. It has an ISO range of 100-32,000, which can be expanded to 50-102,400, which ensures excellent performance in a variety of lighting conditions.

Autofocus System

One of the most impressive features of the Canon R3 is its remarkable 1,053 autofocus points, which are made possible by its cutting-edge Dual Pixel CMOS AF II technology. Because of its vast coverage and better tracking capabilities, it is ideally suited for photographing fast-moving subjects, such as animals in their natural habitat or athletes competing in athletic competitions. The unique Eye Control AF function of the camera enables the user to pick the AF point merely by staring at the appropriate region on the viewfinder to do so, making it one of the camera’s most useful features.

When compared to the R3, which has a powerful focusing system, the Canon EOS 5D IV has a 61-point High-Density Reticular AF system. Although this system is extremely competent, it is not as advanced as the R3’s autofocus system.

Burst Shooting

The ability to take many shots in rapid succession is a crucial tool for photographers who frequently capture action scenes. When using the electronic shutter, the Canon R3 is capable of an astounding continuous shooting speed of up to 30 frames per second, whereas when using the mechanical shutter, it is only capable of 12 frames per second. This unrivaled rate of speed guarantees that you will never pass on an important opportunity.

On the other hand, the Canon EOS 5D IV has a good burst rate of 7 frames per second. While this is a fantastic rate for many types of photography, it may not be able to match the capabilities of the R3 for high-speed action photography.

Image Stabilization

The in-body image stabilization (IBIS) mechanism that comes built into the Canon R3 may give up to 8 stops of correction for blurry images. When working with lenses that do not have image stabilization built in, as well as when trying to achieve crisper shots in demanding shooting settings, this function is of tremendous use.

The Canon EOS 5D IV, on the other hand, does not include IBIS and instead relies on the image stabilization features of lenses that are compatible with the camera.

Video Capabilities

Although both of these cameras have amazing video capabilities, the Canon R3 takes things to an all new level. Because it is capable of shooting 8K RAW video internally at 30 frames per second, it is often considered to be the best option for professional videographers. The camera is also capable of filming in 4K resolution at up to 120 frames per second, which enables users to capture amazing slow-motion video.

Although the Canon EOS 5D IV is also able to take superb video at a resolution of 4K, it is not able to compete with the R3’s outstanding capabilities in this regard.

ISO Range and Low Light Performance

When shooting in low light, the ISO performance of a camera becomes quite important. Even in adverse lighting circumstances, the sensor of the Canon R3 performs exceptionally well in taking photographs with low noise and good resolution because to its extended ISO range that can go as high as 204,800.

The Canon EOS 5D IV, although having a low-light performance that is excellent and an ISO range that can be expanded up to 102,400, is unable to compete with the capabilities of the R3.

User Interface and Controls

Both cameras have user interfaces that are easy to navigate and controls that can be personalized, giving users the ability to adjust various camera settings according to how they want to take pictures.

Because it is a more recent model, the Canon R3 has several controls that have been upgraded and a menu system that is more up to date.

Battery Life

The Canon EOS 5D IV has an edge over its predecessors in terms of the battery life it provides. Because of the DSLR architecture of the camera, it can accommodate a larger battery, which results in longer shooting sessions before the battery has to be recharged.

Due to the fact that it is a mirrorless camera, the Canon R3 has a battery life that is slightly less than average, but it still works rather well.

Connectivity Options

In terms of communication, both cameras are equipped with Wi-Fi and Bluetooth capabilities, allowing for the smooth transfer of images and the shooting of remotely captured content.

In addition, the Canon R3 is equipped with an Ethernet connector, which enables connected communication that is both quicker and more dependable.

Price and Value for Money

The Canon R3, with all of its innovative capabilities and cutting-edge technology, comes at a price that is far more than you would expect. It is designed for both professional photographers and photography amateurs who expect the highest level of performance from their equipment and are ready to spend appropriately.

On the other hand, while being an older model, the Canon EOS 5D IV provides exceptional value for the purchase price. It is a workhorse that is dependable and produces exceptional image quality at a price that is more affordable.


In conclusion, the Canon R3 and the Canon EOS 5D IV are both wonderful cameras, with their own set of advantages and markets for which they are most suited. The R3 stands out as a top-of-the-line mirrorless camera, making it ideal for professionals and advanced enthusiasts who want the newest technology and performance that cannot be matched. On the other hand, the EOS 5D IV continues to be a well-liked option for people looking for a DSLR that is dependable and powerful, and that also produces images of an excellent quality.

As is the case with the purchase of any camera, the choice ultimately depends on the requirements, preferences, and resources of the buyer. Both versions have features and capabilities that will unquestionably enhance your photographic experience, including exceptional image quality.
