If you’ve read more than one or two articles on our blog you’ve likely seen images of MTF charts and heard us discuss testing lenses on the optical bench. But what on earth does that mean, and why do we do it? We’re breaking it down with the best people possible, Roger, Aaron, and our audience surrogate, Ryan.

• Mentioned this episode:
• Imatest
• See the MTF bench in action!
• In this older article, you can see an example of a single slice of MTF, combining 4 quadrants to an average, and developing a range.
• General MTF training article.
• This scientific paper contains images of how we map out the MTF across the field of the lens.
