A 35mm lens is a wide-angle lens that is great for capturing landscapes, architecture, and group shots. It has a wide field of view and is good for capturing a lot of the scene in one shot.

A 50mm lens is a standard lens that is good for general purpose photography. It is often considered a "normal" lens because it approximates the field of view of the human eye. It is good for portraits, street photography, and candid shots.

An 85mm lens is a telephoto lens that is great for portraits and close-up shots. It has a narrow field of view and is good for isolating subjects from the background. It is also good for shooting sports and other fast-moving subjects because it allows you to capture more distant action.

In general, a 35mm lens is good for wide-angle shots and capturing a lot of the scene, a 50mm lens is good for general purpose photography, and an 85mm lens is good for portraits and close-up shots. The choice of lens depends on the type of photography you are doing and the look and feel you want to achieve in your photos.
