Why do old photographers like to use cannon lenses?
When using a long focal length lens, it is usually used to shoot distant scenes. Due to the absorption of air and the influence of diffused light. Therefore, it is not easy to achieve very accurate focusing because of the small contrast of the captured image and the serious extinction of dust particles. When shooting with a telephoto lens above 300 mm, it is still difficult to gather all colors of light at one point, resulting in sub-spectral problems. Based on the above situation, sometimes the image quality of the shot works is not high.
Although the use of long focal length lens is influenced by many factors, its advantages are the main ones. In many fields, such as taking photos of scenic figures, traveling photos, portraits, stands, sports competitions, zoo animals, wild animals, adding close-up auxiliary mirrors, etc. When shooting with a long focal length lens, you should generally use a high sensitivity and a fast shutter to prevent image blur caused by camera shake when shooting with a hand-held camera. In general, in order to keep the camera stable, it is best to fix the camera on a tripod. Try to find something to help stabilize the camera without a tripod.
