I’m using the kit lens that came with the camera. I use only convenient zoom lenses that can change the focal length. For such people, I would like to recommend a single focus lens that can take pictures with good image quality and good blur. Since the focal length of a fixed focal length lens cannot be changed, it is necessary to move and decide the composition, and one of the attractions is that it helps to improve the picture. In this article, we will introduce the recommended models of EF mount lenses that are compatible with Canon SLR cameras that use EF mounts, among other single focus lenses.
What is a single focus lens?
A fixed focal length lens is a lens that cannot be zoomed and has a fixed focal length. When I hear that alone, I feel that the zoom lens is more convenient and easier to use. However, in reality, many photographers love single focus lenses. Below, I will introduce the attractiveness of single focus lenses, which is one of the reasons.
Advantages of fixed focal length lenses
Overwhelming bokeh and high image quality
Many kit lenses for beginners and convenient zoom lenses cannot capture much light called F-number due to the structure of the lens. On the other hand, if you have a single focus lens with many models with a low F value that can capture a lot of light, you can take pictures with a well-blurred background. Another point is that single focus lenses have better image quality than zoom lenses. Due to the structure of the lens, distortion and color bleeding of the subject can be suppressed, and you can enjoy higher-definition photographs.
You can take bright pictures
As mentioned above, a single focus lens can take in a lot of light due to the structure of the lens. As a result, many models allow for smaller minimum F-number settings. When shooting, even in places that are bright enough to live indoors, such as indoors, taking a picture with the camera may cause camera shake or poor image quality. The reason is that there is a bigger difference in brightness between outdoors and indoors than people feel. To solve this, it is basically necessary to change the shutter speed, F value, or ISO sensitivity. However, if you make the photo brighter by lowering the shutter speed, camera shake will occur more easily, and if you make the photo brighter by increasing the ISO sensitivity, the image may become grainy and the image quality may deteriorate. Therefore, by using a lens with a bright F-number, it is possible to take a sufficiently bright picture indoors without forcibly changing the shutter speed and ISO sensitivity settings.
Disadvantages of single focus lenses
I can’t zoom
The disadvantage of fixed focal length lenses is that they cannot be zoomed. Therefore, you cannot adjust the angle of view unless you move and change the shooting position. Use a zoom lens in situations where you want to prioritize usability, such as places where many people gather or where the subject moves around.
About EF mount
What is an EF mount?
The EF mount is the lens mount used in Canon SLR cameras. This lens mount has been used since the latter half of the 1980s and is characterized by its long history of accumulated technology and abundant lens lineup.
