- EOS R3 vs EOS-1D X Mark III vs EOS R5 Feature Comparison
The new Canon EOS R3 is a professional full frame mirrorless camera that’s built for speed with a range of new features to ensure you capture the action.
Here, we examine how the Canon EOS R3 compares to the flagship Canon EOS-1D X Mark III and the equally impressive EOS R5 to help you decide which of our pro cameras is best for you.
The first decision to make is which format between DSLR and Mirrorless best suits your needs and shooting style. Many photographers are more comfortable in shooting with an optical viewfinder and value the traditional feel and usability of a flagship DSLR like the EOS-1D X Mark III. Other advantages of the EOS-1D X Mark II include longer battery life, ideal if you are out on assignment and shooting for long periods of time. On the other hand if you are looking for a more compact lightweight body design and innovative features like advanced subject tracking and In-Body Image Stabilization then the mirrorless EOS R3 or EOS R5 might be a better choice for you.
Taking the leap from and EOS DSLR to and EOS R Mirrorless camera opens up your shooting possibilities to Canon’s new RF lens range which is rapidly expanding and now includes 25 options from wide angle to super telephoto, with compact and affordable entry level options in addition to a range of L series professional lenses with advanced features not offered in the EF lens range. The EF-EOS R lens adapter also offers photographers the option of using their existing EF and EF-S lenses on EOS R cameras with no loss in quality or speed.
