EF Mount Single Focus Lenses

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 Fixed-Focus Lens in Photography?

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.

What is an EF mount lens?

An EF mount lens is a lens compatible with Canon SLR cameras that use an EF mount. We have a wide range of lenses, from genuine lenses sold by Canon to third-party lenses sold by DZOFilm and SIGMA.

Introducing the features of the G mount lenses

A large sensor system used in the medium-format camera “GFX series” developed by Fujifilm. Many people do not know that there are other effects besides image quality that can be obtained by increasing the sensor size. Therefore, in this article, I will introduce the recommended model of G mount lens compatible with GFX series cameras while explaining the sensor size in detail.

About sensor size

What is a sensor?

A sensor is a part that can be said to be the heart of a camera, and has the role of converting the light coming from the lens into an electrical signal. There are various types of sensors such as “Bayer sensor” and “Foveon sensor”.

What is sensor size?

The sensor size refers to the size of the parts described above. The sensor size is the easiest to distinguish among the types of sensors. Differences depending on the sensor size mainly appear in the image quality, dark performance, and the difference in blurring at the same angle of view. By the way, the sensor mounted on the medium format camera that adopts the G mount is a sensor called “medium format digital”, which is about 70% larger than the “full size sensor”.

About G mount

What is G mount?

The G mount is the mount system used in the large sensor system “GFX series” developed by Fujifilm. The lineup includes gem cameras equipped with medium format digital sensors, such as the GFX 50S released in 2017.

Features of G mount

Cameras that use the G mount are characterized by their ability to take high-quality, high-definition photographs created by the large sensor size. The descriptive power that is so precise that it can be used when taking architectural photographs and photographs of cultural heritage can be said to be the greatest strength that can only be achieved with a large sensor.

What is a G mount lens?

A G-mount lens is a lens that can be used with cameras that use a G-mount. The angle of view of the G-mount lens needs to be divided by about 1.26 when converting to 35mm. For example, a 63mm lens is 50mm when converted to 35mm. In addition, all G-mount lenses are dust-proof, drip-proof, and cold-resistant (up to -10 ° C). It can be said that it is a lens that can be used by professionals.
