Lens are divided into wide-angle, medium focus and telephoto according to focal length; they can be divided into fixed focus and zoom according to focal length adjustment.

Wide-angle lenses are mainly used to shoot large scene scenery, medium-focus lenses are used to shoot portraits, humanities, sketches, still life, etc.; telephoto lenses are used to shoot distant scenery, concerts, sports, birds, etc. .

.

Red-circle lenses are more expensive and of better quality. For fixed-focus lenses, red-circle lenses are better than non-red-circle lenses in terms of workmanship and image quality. , but the quality gap is definitely not as obvious as the price gap.

For zoom lenses, the red circle zoom generally has a constant large aperture, while most non-red circle lenses have a floating aperture, and the maximum aperture at the wide-angle end and the telephoto end are different.

The difference between a good lens and an ordinary lens is not obvious when shooting under normal light during the day. Under some extreme conditions, there may be a difference between what can be photographed and what cannot be photographed. If you shoot most of the time when the lighting conditions are good, and generally use the best aperture range to shoot, an ordinary lens can actually do the job. The extra money spent on the red circle lens is mainly to prepare it for extreme environments, haha.
