Using a telephoto lens primarily results in less depth of field and is also associated with more light capture depending on the specific lens and its aperture settings.

Telephoto lenses have a longer focal length, which naturally compresses the background and isolates the subject, leading to a shallower depth of field. This characteristic is particularly valuable in portrait photography or any situation where the photographer wants to emphasize the main subject while softly blurring distractions in the background.

Moreover, telephoto lenses often come with larger maximum apertures, allowing more light to enter the lens. This capability means that photographers can achieve better performance in lower light situations, as well as faster shutter speeds to freeze action.

Therefore, stating that less depth of field and more light capture are relevant effects of using a telephoto lens captures the essence of what differentiates these lenses from standard or wide-angle options.
