Which lens category would you choose for a narrow field of view mapping, under 75 degrees?

Explanation:
For mapping with a narrow field of view, you want a lens that narrows what you capture, which typically means using a longer focal length. Lenses labeled as wide or super wide are designed to cover broader scenes and therefore produce FOVs larger than 75 degrees. A normal angle lens sits in the middle but still doesn’t target the particularly narrow framing you’re after. The single lens option represents a fixed focal length setup that yields a tighter frame, making it the best fit when you need a narrow field of view under 75 degrees.
