The Secret Behind Nikon’s Second Aperture Scale (It’s Genius!)

Описание: Why do Nikon AI lenses have TWO aperture scales?
In this video, we explore the hidden purpose behind the second set of aperture numbers found on Nikon AI and AI-S lenses—and how it ties into Nikon’s ADR (Aperture Direct Readout) system.
You’ll learn:
📷 What ADR is and how it works
🔎 Why Nikon added the second scale
📸 How different Nikon film cameras like the F2AS, F3, F4, and F5 display aperture info
🛠️ How some lenses were AI-converted (and what to look for)
👁️ Why the F6 dropped ADR in favor of digital readouts
Whether you're a Nikon enthusiast, film shooter, or vintage gear collector, this is a deep dive into one of Nikon’s most clever mechanical innovations.
