Overview of Canon R3 and Canon EOS 90D

The Canon R3 is a full-frame mirrorless camera that is aimed primarily at working photographers and experienced amateurs who want to take their photography to the next level.

On the other hand, the Canon EOS 90D is a crop sensor digital single-lens reflex camera that is designed for photographers of intermediate skill level who are wanting to improve their gear without breaking the budget.

Design and Build

Both cameras are top-notch in their respective classes when it comes to the design as well as the quality of the construction. The Canon R3 is built with a magnesium alloy that is both durable and lightweight, and it has weather sealing to ensure it can handle harsh shooting conditions.

The ergonomic design of its grip makes holding it for lengthy periods of time both pleasant and secure. The Canon EOS 90D, on the other hand, is solidly constructed with a polycarbonate body that provides a satisfying sense of weight when held. Despite the fact that it does not have the same amount of weather sealing as the R3, it still provides a satisfactory level of protection.

Image Sensor and Resolution

Innovative Dual Pixel CMOS AF technology is included into the full-frame sensor of the Canon R3, which has a resolution of 24.1 megapixels. This sensor provides remarkable image quality, outstanding performance even in low light, and an amazing dynamic range.

The Canon EOS 90D, on the other hand, has a sensor with 32.5 megapixels and an APS-C format, which allows it to produce high-resolution photographs with rich colors and excellent retention of detail.

Autofocus System

The focusing system is an essential component of every camera, but it is especially important when photographing things that are moving quickly. The Canon R3 is equipped with a cutting-edge Dual Pixel CMOS AF II technology that features 1,053 AF points and covers almost the entirety of the frame.

This technology provides a focusing performance that is both extremely quick and accurate, making it well suited for shooting of both sports and wildlife. On the other hand, the Canon EOS 90D is equipped with a 45-point all-cross-type AF system, which is still dependable but not as advanced as the one found in the R3.

Burst Shooting

The Canon R3 has the most advanced capabilities when it comes to shooting in rapid succession. It is capable of shooting at a remarkable thirty frames per second (fps) while maintaining complete autofocus tracking, guaranteeing that you will never miss a single exciting moment.

In comparison, the Canon EOS 90D has a decent 10 frames per second (fps) burst rate, which is outstanding for most types of photography but falls short when compared to the speed of the R3.

Image Stabilization

The in-body image stabilization (IBIS) included in the Canon R3 is capable of offering up to 8 stops of correction for blur. Because of the superior performance of this stabilization technology, you may shoot handheld at slower shutter speeds without sacrificing the image quality.

The Canon EOS 90D, on the other hand, does not have an IBIS but makes up for this deficiency with lens-based image stabilization whenever suitable lenses are used.

Video Capabilities

The Canon R3 is the superior choice for videographers, despite the fact that both of these cameras provide great video capabilities. It is capable of recording 4K films at up to 120 frames per second and 8K RAW videos at 30 frames per second, producing footage of cinematic quality.

Even though it is still competent, the Canon EOS 90D’s highest video resolution is just 4K at 30 frames per second, and it does not have a raw video option.

ISO Range and Low Light Performance

The Canon R3 has a native ISO range of 100-102,400, which can be expanded all the way up to an astounding 50-819,200, which allows it to perform exceptionally well in conditions with low light levels. This extensive range means that you will be able to shoot excellent photographs even when the lighting conditions are difficult.

When compared to the R3, the native ISO range of the Canon EOS 90D is 100-25,600 and can be expanded to 51,200. This is a respectable range, but it is not on par with the R3.

User Interface and Controls

Both cameras include user interfaces that are easy to navigate and controls that may be personalized. The Canon R3 has a big touchscreen that has a high quality and can be viewed from a variety of angles. Additionally, it has an electronic viewfinder (EVF) that allows for perfect composition.

Because it is a DSLR, the Canon EOS 90D has both an optical viewfinder and a touchscreen that can be adjusted to different angles. Although both are simple to use, the electronic viewfinder (EVF) of the R3 offers a superior real-time preview.

Battery Life

Battery life is quite important, particularly when shooting for extended periods of time. Because the battery capacity of the Canon R3 is greater than that of the Canon EOS 90D, the Canon R3 can operate for a longer period of time on a single charge.

However, it is important to keep in mind that the real battery life varies depending on how the camera is used and the conditions in which it is shot.

Connectivity Options

In terms of connection, both cameras include Wi-Fi and Bluetooth capabilities, which allow for the uploading of images in a smooth manner and the use of smartphone apps for remote shooting.

In addition, the Canon R3 features built-in Ethernet for quicker and more stable wired connections, which can be beneficial in business situations. This feature is included as standard equipment.

Price and Value for Money

A greater price tag is attached to the Canon R3 due to the fact that it possesses more advanced capabilities and performs at a level appropriate for professionals.

On the other hand, the Canon EOS 90D offers a compelling feature set at a price point that is more manageable for the average consumer’s budget. This results in a great value for money.
