Imaging differences and shooting precautions of wide-angle, medium-focus and telephoto lenses

Wide angle, as the name implies, the angle of the photos taken is relatively large. In fact, the lens can shoot more things at the same distance, but there will be some distortion at wide angle. Simply put, it is deformed, square and round. Of course, the higher the wide-angle lens, the better the distortion control.

Hey, I am too lazy to type. Look here.

Wide-angle lens: a lens with a focal length of less than 35MM-when the focal length is smaller than that of the pan/tilt, the lens can record images with a larger angle of view, so it is called a wide-angle lens. The perspective of wide-angle lens is exaggerated, showing obvious perspective effect and emphasizing the sense of distance. It is widely used in news photography and landscape photography and will have a strong visual impact.

Medium focus lens: a lens with a focal length of 85 mm ~ 135 mm-a lens with a focal length of 1.5 ~ 4 times the focal length of the head is generally called medium focus. The photo taken at this focal length has the smallest deformation, can correctly reflect the shape of the subject, and it is relatively easy to design it into a super-large aperture. In portrait photography, medium focus is the most commonly used.

Telescope head: a lens with a focal length of more than 200MM-it has a small sense of distance and can compress the perspective of the landscape. (Easy to shake, try to use a tripod)
