What are the main differences between a 35mm and a 55mm lens in terms of focal length and how do these differences impact photography?

A 35mm lens has a shorter focal length than a 55mm lens, which means it captures a wider field of view. This makes it ideal for landscapes and group shots. On the other hand, a 55mm lens has a longer focal length, allowing for closer shots and better compression of the background. This makes it great for portraits and capturing details. The choice between the two lenses depends on the desired composition and style of the photograph.
