Application of large aperture fixed focus lens

Lead: Beginners who have just stepped into photography learning often can't tell the difference between large aperture and small aperture. Today I will explain the application and advantages of large aperture for you. Just interested friends, hurry up and learn!

Benefits of applying large aperture to large aperture fixed focus lens

If you have a basic understanding of photographic exposure, you will know that the larger the aperture, the more light will enter at the same time, which will enable you to keep the photos clear without improving ISO when shooting in low light environment (such as indoors, at night, etc.). ) (see the article on safety shutter for details) to improve the quality of your photos.

Besides effectively increasing the shutter speed, it has another well-known effect? Shallow depth of field. What is the shallow depth of field? Before the Qing Dynasty, after Mongolia? The effect can not only highlight the subject, but also make the photo full of poetry. If you add some tricks, you can also use the big aperture to shoot scattered scenes with hearts or other shapes, which is very interesting for holiday shooting!

Prime lens? Is it good or bad?

Many students saw it? Fixed focus? Second, at the first time, I felt that the focal length of the fixed-focus lens could not be adjusted casually, which was very inconvenient. Undoubtedly, if you can't zoom, it will bring some inconvenience, but if the environment permits, you can not only zoom by moving your body, but also make you develop the habit of thinking more and finding more angles, which will make your skills more advanced. Another advantage is volume and weight. Generally speaking, the fixed-focus lens is simpler than the zoom lens, so many fixed-focus lenses are very light and small (such as the standard 50mm fixed-focus lens), with clear imaging and high quality. Fixed-focus lenses generally have little deformation, which avoids the trouble of repairing lens deformation after production.

Therefore, under the factors of cost performance, volume and weight, the large aperture fixed-focus lens is very suitable for novices, especially those with low prices. It is suggested that students consider starting and enjoy the fun brought by large aperture!

Shooting skill

(1) Be serious and focused

When the aperture is fully open, the depth of field is very shallow, so you need to focus carefully. Move a little and you will have a chance to blur the subject!

Choose the right theme

Large aperture has the characteristics of deep and shallow scenery. When shooting, you might as well choose some subjects that can make use of shallow depth of field, such as portraits and close-ups. When taking landscape photos, you can try to use objects (focus) to set off the scenery (scattered scenery) and increase the number of subjects.

Although the effect of large aperture and shallow scenery is attractive, don't abuse it. For example, when shooting a traveling portrait, if the depth of field is too shallow, the background will become blurred, so that the reader doesn't know where he is when shooting, and it will lose its meaning!

(4) Walk around to find the angle.

Because focusing is not as convenient as zooming, you can move more and explore interesting angles and things with your photographic eyes, which is also very good for your photography skills!
