Mirrorless cameras revolutionize the world of photography, offering a more compact and versatile alternative to traditional DSLRs. In another article, we compare Mirrorless lenses vs DSLR lenses. One of the key benefits of mirrorless cameras is the ability to switch lenses, allowing photographers to customize their gear to suit different shooting scenarios.
However, with so different lenses available on the market, it can be overwhelming to choose a lens for mirrorless camera and the right one for your needs. In this article, we will discuss the key factors to consider when choosing a lens for your mirrorless camera.
1. Consider of photography type

The first step in choosing a lens for mirrorless camera is to think about the type of photography you want to do. Different lenses are designed for different purposes. So, it’s important to choose one that is well-suited to your shooting style.
For example, if you’re interested in portrait photography, you’ll want a lens with a wide aperture (f/1.8 or wider) to create a shallow depth of field and blur the background. On the other hand, if you’re interested in landscape photography, you’ll want a lens with a wider field of view, such as a 16-35mm or 24-70mm lens.
2. Consider the sensor size of your camera
Another important factor to consider when choosing a lens for mirrorless camera is the size of your camera’s sensor. Mirrorless cameras come in a variety of sensor sizes, including full-frame, APS-C, and micro four-thirds. The size of your sensor will impact the field of view and depth of field of your images. For example, if you have a micro four-thirds camera, you’ll need to choose a lens with a smaller focal length to achieve the same field of view as a full-frame camera with a longer focal length.
3. Consider the length of the lens
The focal length of a lens determines how much magnification it provides, as well as its field of view. Lenses with longer focal lengths (e.g. 85mm or 135mm) are ideal for portrait photography, while lenses with shorter focal lengths (e.g. 16mm or 24mm) are better suited for landscape photography and street photography. It’s worth noting that many mirrorless cameras have crop factors. it will impact the effective focal length of the lens. For example, a 50mm lens on an APS-C camera will have an effective focal length of around 75mm.
4. Consider the aperture of the lens


The aperture of a lens refers to the size of the opening that allows light into the camera. A wider aperture (indicated by a lower f-number) allows more light to enter the camera, which is ideal for low-light situations and creating a shallow depth of field. However, wider aperture lenses tend to be more expensive and heavier. If you’re on a tight budget, consider a lens with a smaller aperture (e.g. f/4) and invest in a good quality tripod to help you capture sharp images in low light.
5. Consider the lens mount
Mirrorless cameras come in a variety of mounts, including Sony E-mount, Canon RF-mount, and Fujifilm X-mount. It’s important to choose a lens that is compatible with your camera’s mount, as lenses designed for other mounts will not work with your camera. It’s also worth noting that some lens manufacturers make lenses for multiple mounts. So, you can switch between different camera brands without having to buy a new set of lenses.
6. Consider the size and weight of the lens
One of the key benefits of mirrorless cameras is their compact size and portability. However, this advantage can be negated by choosing large and heavy lenses. If you plan on carrying your camera and lens for long periods of time, consider a smaller and lighter lens for mirrorless camera.
