Street photography is a genre of photography that captures candid moments of people and places in public spaces. It is often associated with wide-angle lenses, which allow the photographer to get close to the subject and capture more of the surrounding context. However, some street photographers prefer to use telephoto lenses, which have a longer focal length and can create a different perspective and effect.

Telephoto lenses have some advantages and disadvantages for street photography. On the positive side, they can help the photographer to isolate the subject from the background, creating a shallow depth of field and a more dramatic composition. They can also allow the photographer to shoot from a distance, without being noticed or disturbing the scene. This can be useful for capturing candid expressions and emotions, or for photographing in places where it might be unsafe or inappropriate to get too close.

On the negative side, telephoto lenses can also pose some challenges for street photography. They are usually heavier and bulkier than wide-angle lenses, which can make them more difficult to carry around and handle. They also require a faster shutter speed to avoid camera shake, which can limit the creative possibilities of using motion blur or low-light conditions. Moreover, they can create a more detached and voyeuristic feeling, which might not suit the style or intention of some street photographers who want to engage with their subjects and environment.

Ultimately, the choice of lens for street photography depends on the personal preference and vision of the photographer. There is no right or wrong answer, as long as the lens serves the purpose and message of the image. Some street photographers might stick to one lens for consistency and simplicity, while others might switch between different lenses depending on the situation and opportunity. The most important thing is to experiment and have fun with street photography, and to find your own voice and style.
