What Is A Mirrorless Camera – Are They Really Better Than DSLRs?
If you are looking for a new camera, you may have come across the term “mirrorless camera”. But what does it mean, and how does it differ from a traditional DSLR camera? In this article, we will explain the basics of a mirrorless camera, compare it with a DSLR, and explore the pros and cons of using one. We will also help you decide between a DSLR and a mirrorless camera, and give you some tips on choosing the best mirrorless camera for your needs.
Definition | What is a Mirrorless Camera
A mirrorless camera is a type of digital camera that doesn’t have a reflex mirror inside the body. A reflex mirror is a device that reflects the light coming from the lens to an optical viewfinder, which allows you to see what the lens sees. When you press the shutter button, the mirror flips up and exposes the image sensor, which captures the photo.
The Basics of a Mirrorless Camera
Since mirrorless cameras don’t have a reflex mirror, they don’t need an optical viewfinder. Instead, they use an electronic viewfinder (EVF) or a rear LCD screen to display the image from the sensor. This means that you can see a live preview of your photo, with adjustments for exposure, white balance, and other settings. You can also review your photos and videos on the screen without taking your eye off the camera.
Another feature of mirrorless cameras is that they have interchangeable lenses, just like DSLRs. This means that you can change the lens according to your shooting situation and preference. However, mirrorless cameras use different lens mounts than DSLRs, so you need to make sure that the lens is compatible with your camera model. Some mirrorless cameras also have adapters that allow you to use DSLR lenses on them.
How Does a Mirrorless Camera Work?
A mirrorless camera works by letting the light pass through the lens and directly onto the image sensor, which converts it into digital data. The sensor is always exposed to light, unlike in a DSLR where it is hidden by the mirror until you take a photo. This allows the camera to use contrast-detection autofocus (CDAF) or phase-detection autofocus (PDAF) to focus on the subject. CDAF measures the contrast of the image on the sensor and adjusts the lens until it is sharp. PDAF uses dedicated pixels on the sensor to detect the phase difference of light from different parts of the lens and calculates how much to move the lens to achieve focus.
DSLR vs Mirrorless Cameras: The Differences
Distinguishing Features between DSLR and Mirrorless
The main difference between DSLR and mirrorless cameras is the presence or absence of a reflex mirror and an optical viewfinder. This affects not only how you compose your shots, but also how the camera operates and performs. Here are some of the key features that distinguish DSLR and mirrorless cameras:
| Feature | DSLR | Mirrorless |
|---|---|---|
| Size and Weight | Generally larger and heavier due to mirror box | Smaller and lighter, but high-end models can be sizable |
| Viewfinder | Optical viewfinder with no lag | Electronic viewfinder with live preview |
| Autofocus | Phase-detection for optical viewfinder, slower in live view | Contrast-detection or phase-detection on sensor, faster in all modes |
| Battery Life | Longer battery life | Shorter battery life, but improving with newer models |
DSLRs use phase-detection autofocus (PDAF) when using the optical viewfinder, which is fast and accurate for tracking moving subjects. However, when using live view or shooting video, DSLRs switch to contrast-detection autofocus (CDAF), which is slower and less reliable. Mirrorless cameras use either CDAF or PDAF (or both) on the sensor, which means that they can focus quickly and accurately in both stills and video modes. However, some older or cheaper mirrorless cameras may have slower or less accurate autofocus than DSLRs.
Performance Comparison: DSLR vs Mirrorless
While the features of DSLR and mirrorless cameras can vary depending on the model and brand, there are some general trends in how they perform in different shooting scenarios. Here are some of the common situations where DSLR and mirrorless cameras may have an edge over each other:
| Shooting Scenario | DSLR | Mirrorless |
|---|---|---|
| Sports and Wildlife | Preferred for fast and reliable autofocus, longer battery life, and optical viewfinders | Some catching up with fast autofocus, offer advantages like silent shooting, higher frame rates, and wider autofocus coverage |
| Landscape and Travel | Preferred for better dynamic range and low-light performance, weather sealing, longer battery life, and optical viewfinders | Preferred for smaller and lighter build, features like live histogram, focus peaking, and exposure zebras for optimal exposure and focus |
| Portrait and Studio | Both can be used, DSLRs offer control over depth of field and bokeh with larger sensors and wider aperture lenses, better compatibility with external flashes and strobes | Mirrorless cameras offer features like face and eye detection, live preview, and tilt-swivel screens, wider selection of lenses for different focal lengths and effects |

- Compare features and performance: When comparing different cameras, you need to look at their features and performance in relation to your goals and budget. Some of the key features and performance aspects to compare are:
- Sensor size: The sensor is the part of the camera that captures light and converts it into digital data. The size of the sensor affects the image quality, low-light performance, dynamic range, depth of field, and noise level of the camera. Generally speaking, larger sensors produce better images than smaller sensors.
- Resolution: The resolution is the number of pixels that the sensor can capture in one image. The resolution affects the sharpness and detail of the image. Generally speaking, higher resolutions produce sharper images than lower resolutions. However, higher resolutions also require more storage space and processing power than lower resolutions.
- Frame rate: The frame rate is the number of frames that the camera can capture in one second. The frame rate affects the smoothness and realism of the video. Generally speaking, higher frame rates produce smoother videos than lower frame rates. However, higher frame rates also require more storage space and processing power than lower frame rates.
- ISO: The ISO is the measure of the sensitivity of the sensor to light. The ISO affects the brightness and noise level of the image. Generally speaking, higher ISOs produce brighter images than lower ISOs, but also produce more noise than lower ISOs. Noise is the grainy or speckled appearance of the image that reduces its quality and detail.
- Aperture: The aperture is the opening of the lens that controls how much light enters the camera. The aperture affects the depth of field and bokeh effects of the image. Depth of field is the range of distance that is in focus in the image. Bokeh is the quality and shape of the out-of-focus areas in the image. Generally speaking, wider apertures produce shallower depth of field and smoother bokeh than narrower apertures, but also reduce the sharpness and detail of the image.
- Shutter speed: The shutter speed is the length of time that the shutter remains open to expose the sensor to light. The shutter speed affects the motion blur and exposure of the image. Motion blur is the streaking or blurring effect of moving objects in the image. Exposure is the amount of light that reaches the sensor, which determines how bright or dark the image is. Generally speaking, faster shutter speeds produce sharper images with less motion blur than slower shutter speeds, but also produce darker images with less exposure than slower shutter speeds. You may also want to know about shutter count in a dslr which we have discussed in one of our articles.
