Camera Lens Field of View Comparison Chart - W1 to W4 Angles #2019740 (License: Personal Use)

This diagram illustrates four camera lens configurations labeled W1 through W4, displaying their respective horizontal field-of-view angles: 39°, 44°, and two at 50°. While W1 and W2 show clean circular imaging areas, W3 and W4 include a cross-shaped obstruction-likely from an IR cut filter or housing-causing vignetting at the edges despite the same 50° angle. The visual contrast highlights trade-offs between wide-angle coverage and optical clarity.
