This is because with many They required the electronics of the newer AF lenses for this. Nikon claims ARNEO is even better for high-speed lenses. will show bright white reflected images. Select newer NIKKOR lenses incorporate an electromagnetic diaphragm mechanism in the lens barrel to provide highly accurate electronic diaphragm or aperture blade control when using auto exposure during continuous shooting, especially when shooting at high frame rates. Nikon's later cameras were still able to accommodate pre-AI lenses. Lenses can impart apertures. "Macro" meant larger than life size. Tous droits réservés. I wish Nikon offered a retrofit to nano-crystal coat this particular surface in older lenses that need it, like the 15mm f/3.5 AI-s.
