Excerpt: I use this lens for interiors photography. Sometimes a 24 isn't wide enough. The 20mm fits the sweet spot without being garishly wide. No autofocus but depth of field at this focal length is abundant. It's built very well. sharp, compact. Just what I needed.
Pros: Durable, Lightweight, Rugged, Strong Construction
Excerpt: I recently bought a Nikon D810, several AF-S lenses & lighting equipment. When it came to choosing a wide angle, I purchased this manual focus from B&H to keep my mind in the game and think about exposure and focus rather than being totally automated.
