This is especially beneficial for establishing focus and composing shots in low light conditions.Ĭanon’s large aperture lenses can be divided into three categories: On cameras that use an optical viewfinder, such as the EOS 77D and EOS 800D, large aperture lenses provide an additional advantage-they allow more light to enter the optical viewfinder, which results in a clearer, brighter view. (Read: How Do I Focus Accurately With Manual Focus?) For some scenes, it might be more effective to shoot in Live View using a magnified display and manual focusing (MF). However, large aperture lenses also have an extremely shallow depth-of-field, which can make it difficult to establish precise focus. This helps to prevent camera shake, even when shooting handheld. The large amount of light that is able to enter the lens and reach the image sensor due to the large aperture means that it is possible to maintain a fast shutter speed even in low light conditions, such as when shooting indoors, at night, or in dim lighting. The larger the maximum aperture, the easier it is to obtain a prominent background blur effect. They generally have a maximum aperture of f-number f/2.8 or smaller, although on a variable aperture zoom lens, this maximum aperture depends on the focal length used. The larger opening gives the lens a large maximum aperture (small f-number), and are also why such lenses are also often called “bright” lenses. Large aperture lenses are also known as large diameter lenses due to the relatively large size of the “opening” that allows light into the lenses. They give you a brighter, clearer view if you are using an optical viewfinder. The extremely shallow depth-of-field requires more effort to ensure tack-sharp focusing.Ĥ. They let you shoot with a fast shutter speed even in low light conditions-good for preventing camera shake.ģ. The large maximum aperture makes it easy to achieve creamy bokeh (background blur).Ģ. With their small f-numbers, large aperture lenses not only make it possible to achieve a creamy background blur effect, they also have a number of other advantages.
