full-frame mirrorless camera for beginners: fast autofocus

New tech helping the digital marketing industry

Date: 08/14/2022

Over the years, we came across some essential tools for digital marketing. A fast and responsive computer, for example, could make a digital marketer’s life much easier as oftentimes he or she is multitasking for several projects at once on their computer. But one noteworthy tool is a good camera, especially for new photgraphers beginning to work with other marketers. Not so long ago, camera manufacturers introduced mirrorless cameras to the general public and shortly after, the full-frame cameras.

Full-frame mirrorless cameras often provide better manual focusing compared to DSLR cameras. However, many of the newer mirrorless cameras also come equipped with faster, more accurate autofocus.

So, which full-frame mirrorless camera with fast autofocus is best? Here are the top picks and a few helpful tips for selecting the right camera for your needs.

The Fujifilm X-T4 is a state-of-the-art device featuring advanced image stabilization and the fastest autofocus in a mirrorless camera. It includes a five-axis sensor for in-body image stabilization (IBIS) to eliminate camera shake and keep your shots sharp and clear.

The fast autofocus works well when snapping still images or recording 4K video. It also includes an innovative subject-tracking feature that works in low-light conditions.

The Fujifilm X-T4 is recognized as a reliable full-frame mirrorless camera with fast autofocus and easy-to-navigate controls. If the price is within your budget, the Fujifilm X-T4 is worth the cost.

The Olympus OM-D E-M10 Mark IV is a great option for those with a smaller budget. It has a 20MP sensor and a convenient flip-down monitor with a dedicated selfie mode. It also boasts a simple touch screen menu, allowing anyone to customize their settings and capture better shots.

As with the Fujifilm X-T4, the camera includes in-body image stabilization, but with 4.5 shutter speed steps instead of 6.5. The autofocus is not as fast or accurate compared to the X-T4. However, the camera costs a fraction of the price of the other options and still produces decent images.

The Sony A7 III includes an advanced 24.2MP full-frame sensor with a dynamic range. As with most of Sony’s cameras, it produces rich colors and sharp images, even in low-light settings. It also has a combination autofocus system that uses phase detection and contrast detection.

The phase-detection AF system includes 693 detection points while the contrast system includes 425 detection points. The Sony A7 III autofocus system is exceptionally accurate, but not quite as fast compared to the Fujifilm X-T4.

Full-frame mirrorless cameras often provide better manual focusing compared to DSLR cameras. However, many of the newer mirrorless cameras also come equipped with faster, more accurate autofocus.

So, which full-frame mirrorless camera with fast autofocus is best? Here are the top picks and a few helpful tips for selecting the right camera for your needs.

The Sony A7R IV is one of the newest mirrorless cameras from Sony. It is also the world’s first full-frame camera with a back-illuminated 61-megapixel sensor. It offers a superior dynamic range and more impressive colors compared to most other options.

The Sony A7R IV includes a more advanced autofocus system compared to the Sony A7 III. The A7R IV includes real-time tracking and real-time eye autofocus to quickly detect and track human and animal subjects. The Sony A7R IV is a top choice for those that need to capture images quickly without waiting for a sluggish autofocus system.

The Canon EOS R5 full-frame mirrorless camera is a top-of-the-line camera with a 45-megapixel sensor and 8K video recording. It can shoot continuous images at 12 frames per second with the mechanical shutter and 20 frames per second with the electronic shutter.

The Canon EOS R5 is also one of the few cameras to rely on deep learning technology. The autofocus system tracks people and animals using advanced detection of eyes, faces, and heads. However, this is also one of the most costly options.



The single-lens reflex (SLR) camera is the traditional camera professional photographers used for many decades. The camera has a single lens that reflects an image to the viewfinder and records it on film. The film then requires developing.

A digital single-lens reflex (DSLR) camera replaces the analog mechanics of the SLR camera with a digital sensor. Instead of needing to develop film, the images are stored digitally. Recording images digitally allows for a wider range of built-in features, such as optical viewfinders, greater customization, and digital autofocus.

Mirrorless vs DSLRs

Compared to DSLR cameras, mirrorless cameras are often lighter and more compact. They also feature fewer moving parts, which makes them less prone to damage.

Mirrorless cameras tend to provide better focusing compared to DSLR cameras, whether you prefer manual focus or autofocus. A mirrorless camera includes focus peaking, which helps with manual focusing by highlighting the areas that are focused.

The autofocus system is also often superior in mirrorless cameras. The latest mirrorless cameras feature faster, more accurate autofocus.

Pro tip: Autofocus is helpful in low-light and dim environments as you can switch between AF and MF to find the right setting for your shots. 

Full Frame Mirrorless Cameras Auto-Focus

Autofocus is available on all types of digital cameras, whether you want a DSLR or mirrorless camera. However, the best full-frame mirrorless cameras come equipped with the fastest autofocus systems on the market.

While older mirrorless cameras may feature slower autofocus, some models provide greater accuracy. Instead of relying on phase detection, many mirrorless cameras use contrast detection to calculate the distance between the camera and the subject.

Do Professional Photographers Use Auto Focus?

Most professional photographers stick to manual focus, but some prefer to use autofocus. There are advantages to both options, depending on the situation and style of photography.

For example, street photographers sometimes prefer the speed and accuracy of a quality autofocus system. They can quickly snap photos and devote more attention to the composition of their shot. Wildlife photographers and sports photographers may also use autofocus to capture their fast-moving subjects.

Best Mirrorless Camera for Beginners Using Auto Focus

The Fujifilm X-T4 stands out as the top pick for the best mirrorless camera for beginners. It is one of the most popular mirrorless cameras and is available in a variety of packages, including options with or without a lens.

The built-in image stabilization and fast autofocus ensure crystal clear photographs in almost any setting. You do not need to possess any photography skills to take great photos with the Fujifilm X-T4.

In the end, all five of the cameras discussed are quality cameras from trusted manufacturers. The Canon EOS R5 is the premium choice for those with an unlimited budget. The Sony A7 III and the Sony A7R IV are closely matched. The Olympus Mark IV is the best budget mirrorless camera. However, the Fujifilm X-T4 provides the best value for your money, due to its reasonable price tag and lightning-fast autofocus.

Our Personal Pick

Fujifilm X-T4 with XF18-55mm Lens

We believe the current bundle offered for this product on Amazon as well as its performance makes it the editor’s pick. 

Sony A7R IV would be the runner-up in this selection as you can feel its premium-built quality while holding it. However, the approx. $600 increase, compared to Fuji, pushes us more towards the X-T4.
