Lenses and Photography Vocabulary

I would use a telephoto lens when you have a large landscape area and you're trying to focus on the small details and you have bright lighting.

I would use a prime lens where you have low light and where you want to have fine details.

I would use a wide-angle lens when I have a lot to fit into a frame, like a big group picture.
