Máy ảnh Mirrorless là gì? Máy ảnh Mirrorless có đặc điểm gì?

If you’re new to the world of photography, you might be wondering, what exactly is a mirrorless camera? In this article, we’ll explore the key characteristics of mirrorless cameras and why they have become a popular choice among photography enthusiasts.

What is a Mirrorless Camera?

A mirrorless camera is a digital camera that doesn’t have a mirror or an optical viewfinder. Unlike DSLR cameras (which stands for Digital Single-Lens Reflex), mirrorless cameras utilize a different technology to capture images. Instead of a mirror reflecting light to the viewfinder, mirrorless cameras rely on a digital sensor and an electronic viewfinder.

As you start shooting with a mirrorless camera, you’ll notice that the viewfinder displays the image in real-time, allowing you to see the exact result before capturing it. This innovative design eliminates the need for a bulky mirror and prism apparatus, resulting in a more compact and lightweight camera body.

Structure and Working Principle


The structure of a mirrorless camera comprises several components, including the lens, shutter, image sensor, and electronic viewfinder. Unlike DSLR cameras, mirrorless cameras simplify the overall design by eliminating the mirror box and prism. This streamlining allows for a smaller, sleeker camera body.

Working Principle

When you take a photo with a mirrorless camera, light passes through the lens and directly onto the image sensor. The electronic viewfinder then takes the image information from the sensor and displays it in real-time. The camera’s shutter remains open until you press the capture button, ensuring that you capture the desired moment.

With the absence of a mirror and prism apparatus, the distance between the lens and the sensor surface is considerably shorter, resulting in a compact and portable camera body.

Highlights of Mirrorless Cameras


One of the standout features of mirrorless cameras is their compact size and lighter weight compared to DSLR cameras. This compactness makes them highly popular among photographers who value portability without compromising on image quality. In recent years, mirrorless cameras have gained significant traction in the market due to their convenient size and impressive performance.


Lenses play a crucial role in producing beautiful and high-quality photos. With the advancement of mirrorless camera technology, manufacturers have actively developed a wide range of lens options to cater to different shooting styles and preferences. Like DSLR cameras, mirrorless cameras employ bayonet mounts to attach interchangeable lenses, providing flexibility and versatility to photographers. Each camera brand offers its own proprietary lens mount, and third-party manufacturers also contribute to expanding the available lens selection.


Despite their compact size, mirrorless cameras can accommodate sensors that are comparable in size to those found in DSLR cameras. Canon, Nikon, and Sony, for example, offer full-frame sensors for both DSLRs and mirrorless cameras. Moreover, companies like Fujifilm have gone even further by offering medium format sensors, which are larger than full-frame sensors. This means that mirrorless cameras can provide excellent image quality on par with their DSLR counterparts.

Comparing Mirrorless and DSLR Cameras

To understand the differences between mirrorless and DSLR cameras, let’s take a closer look at some of the key aspects:


Mirrorless cameras have a distinct advantage when it comes to size. The compact and lightweight body of a mirrorless camera is a result of careful optimization of the sensor and battery, as well as reduced camera controls. DSLR cameras, on the other hand, require space for the mirror and optical viewfinder, making them bulkier and heavier.

DSLR cameras utilize an optical viewfinder, while mirrorless cameras rely on an electronic viewfinder. Initially, electronic viewfinders faced limitations in terms of resolution and grayscale representation. However, advancements in technology have made electronic viewfinders comparable in clarity to their optical counterparts. Some mirrorless cameras even feature hybrid viewfinders that combine optics with electronics, offering users the best of both worlds.

Focus Ability

In the past, DSLR cameras were known for their superior autofocus capabilities, particularly in low-light conditions. However, mirrorless cameras have caught up and even surpassed DSLRs in certain areas. Cameras like the Sony A6300 boast impressive autofocus speed, narrowing the gap between the two camera types. DSLRs still excel at capturing fast-moving subjects, making them popular among sports and wildlife photographers.

Battery Duration

Battery life is a concern for mirrorless cameras, as they rely heavily on battery power. With mirrorless cameras, the LCD screen is often active, and the electronic viewfinder requires power to function. Consequently, mirrorless cameras typically offer fewer shots per charge compared to DSLRs, which require less battery power for their screens and other features.

Image Stabilization

In-body image stabilization has become a standard feature among mirrorless cameras, adding an advantage over DSLRs. While DSLRs mainly rely on lens stabilization, mirrorless cameras provide stabilization on both the camera body and the lens. This dual stabilization system increases the chances of capturing sharp photos, particularly in situations where camera shake is a concern.

In conclusion, mirrorless cameras are a remarkable innovation that offers photographers a portable and versatile alternative to traditional DSLRs. With their compact size, extensive lens options, and impressive image quality, mirrorless cameras have firmly established themselves as a popular choice among photography enthusiasts.
