How Mirrorless Cameras Works

What is a mirrorless camera? What do you think differentiates the mirrorless camera from a DSLR camera? If you’re new to the world of interchangeable lens cameras, it can be confusing to know which type is right for you. For this article, however, I want to tell you how the mirrorless camera works.

How Mirrorless Cameras Works

Here is how mirrorless cameras works?

While the DSLR uses a mirror mechanism to reflect light into the optical viewfinder or transmit it directly to the camera sensor, the mirrorless camera does not have the mirror mechanism (hence the name), which means that light always passes through the lens on the image sensor. Because light is not reflected by the optical viewfinder any longer, mirrorless cameras will typically depend on the electronic viewfinder (EVF) and LCD screens, which essentially display what the image sensor sees. Due to the lack of mirror mechanism and optical lens, mirrorless cameras may be simplified, made lighter, and thinner compared to DSLRs.

On the other hand, the invisible camera is mechanically simpler – the light passes through the lens (n​​°1) directly towards the image sensor (n°4), and the optical viewfinder is replaced by the electronic viewfinder (n°9) which simulates the image sensor. In normal operation, the mechanical shutter (n°3) remains open and is generally only used at the end of the exposure.

Since there is no mirror and in five directions, the distance from the edge (that is, the distance between the lens holder and the image sensor) can be significantly shortened in mirrorless cameras, as shown above. Because of this, most unmatched camera covers are thinner and lighter than DSLR cameras.

A good mirrorless camera have many advantages over DSLRs. Regardless of the potential lightweight and large quantities of the camera itself, using electronic viewfinders to bring several benefits to the photographers. Given that everything is copied directly from the sensor of the image, the settings of the camera like the saturation, contrast, and the white balance can be displayed directly in the viewfinder and overlays of additional information, including live graphics, can be placed in the viewfinder. This allows photographers to see exactly what they want to take a picture of.

In addition to the fast contrast-detection system or the sensor phase-detection system, you can take advantage of the possibility to zoom in on the target to check the focus. You should use the maximum focus, face detection and other powerful features to guarantee precise focusing with each shot. When capturing images in broad daylight, the electronic viewfinder can be used to check images instead of relying on the rear camera LCD screen.

Meanwhile, mirrorless cameras have a list of their flaws. First, the electronic viewfinder can only be active when the camera is turned on, and the image sensor turned on, which can significantly affect the life of the camera battery.

Second, the electronic viewfinder can cause significant delays, power outages, and high contrast, which can make it difficult for some photographers. When it comes to autofocus, the latest models of mirrorless cameras can be very fast and precise, but not very good at taking quick photos, especially in low light conditions.

How to protect your mirrorless camera

Although mirrorless cameras are generally well-built devices, they are still electronic devices that have glass components, among other things.

Of course, this can harm them.

There are several options to protect your camera like no other. The first two products we use for all our cameras are the lens hood and the UV filter. These are two inexpensive products that help protect the unsurpassed viewfinder.

The lens cap, also called sunscreen, is located above the end of the lens and is primarily designed to reduce glare from the sun. However, in my experience, it also works very well to protect the lens end from bumps and scratches when you hang the camera on your shoulder, and I never go anywhere without the lens capon the camera.

The UV filter is a screw filter that attaches directly to your lens. The only function with a digital camera is to protect the glass element at the end of the lens. However, since replacing lenses can be expensive, and the cost of UV filters is between $ 15 and $ 40, replacing a scratch lens filter is much cheaper than buying the whole lens.

You can literally drop a camera on concrete a few meters high and break the sunscreen and the UV filter. However, the camera and lens will be in good condition because the shocks were attenuated and absorbed by these components.

I’m not saying that the UV filter and the lens cap mean you can drop the camera on concrete, but in my opinion, it’s certainly a worthwhile investment.

Another thing that should be in our head is the camera strap. Although most cameras come with a manufacturer’s belt, we often think that a third-party strap is more practical and effective. My favorite belts are from Peak Design, and we use both the shoulder strap and the wrist strap.

Jess likes custom bars like colorful Etsy and IMO camera belts.

I can also recommend investing in a decent camera bag for the unsurpassed camera, which I will cover in more detail in the next section on traveling with your unsurpassed camera.

After all, it may be worth buying the camera when purchasing a specific warranty or accidental damage cover, or if possible, soon after. This protects the camera from various malfunctions and is generally a worthwhile investment. Here are some options.

How to clean the mirrorless camera

To be honest, I don’t do much cleaning with the camera apart from keeping the lens clean and making sure there isn’t a lot of dirt or dust outside the camera.

To do this, I use an air blower and microfiber fabrics.

The sensors of mirrorless cameras are indeed particularly likely to generate visible dust on your photos. Sometimes I use an air blower to remove the dust that reaches a certain point.

However, I personally use a more thorough cleaning specialist. See the next section on camera maintenance for more tips. I also recommend consulting your user guide, which will likely contain the cleaning and maintenance tips that the manufacturer recommends for your camera model.


So, this is how a mirrorless camera works. Mirrorless cameras, especially the more compact models, are generally a good choice for ordinary photographers who may not care about the shorter battery life and are looking for a camera that they can easily capture with them.

For advanced users, this is a bigger mistake, but you need to define your needs before making the right choice. In terms of functioning, ensure you have the tips of how the camera works before purchasing.
