Is it easy to choose the parameters for cinematography lenses?

The parameter selection of cinematography lenses is not complicated, mainly considering factors such as focal length, aperture, and anti shake function. ‌
Focus section selection
Focus is one of the first factors to consider when choosing a lens, as it determines the angle of view of the lens and the width range of the scene in the frame.
Wide angle lenses (usually below 24mm) are suitable for shooting wide scenes, such as Vlogs and self media videos, and can capture wider images, making them suitable for panoramic and handheld selfies.
The focal range of standard lenses (between 35mm and 50mm) is closest to the natural viewing angle of the human eye, suitable for most scenes, especially portraits and dialogue scenes, and can maintain a natural image while avoiding distortion.
A telephoto lens (over 70mm) can zoom in on distant objects, highlight the subject, and compress the background, making it suitable for long-distance shooting or scenes that require attention to detail, such as close-up shots or wildlife shots.
Aperture selection
The size of the aperture affects the amount of light entering the lens and the clarity range of the image.
Large aperture lenses (F1.4 or F2.8) are suitable for shooting in low light conditions and can produce good blurring effects, making them suitable for capturing people or scenes that require highlighting the subject.
Small aperture lenses (F4 or above) perform better in well lit environments, providing a larger range of clarity and suitable for capturing scenes such as landscapes and buildings that require rich details to be displayed.
image stabilization
The anti shake function is crucial in video shooting, especially during handheld or motion shooting, which can effectively reduce the shaking of the image and maintain its stability. The anti shake function compensates for camera shake by moving the lens group inside the lens, and is usually most effective in telephoto shooting or low light environments.
