Nikon AF-S 24mm f1.4 Lens

24mm f/1.4G ED Lens Provides Ultra-Fast Response for Wide-Angle Applications
Perhaps one of the most hotly anticipated lenses in recent memory, the new AF-S NIKKOR 24mm f/1.4G ED lens blends a natural yet versatile 24mm perspective with an ultra-fast f/1.4 aperture expanding an existing collection of over 60 NIKKOR interchangeable lenses. The f/1.4 maximum aperture allows photographers to shoot handheld in low light and provides dramatic separation between subject and a softened background. In a wide variety of photographic situations, both FX- and DX-format shooters will enjoy the benefits of extra-bright f/1.4 viewing, superb image quality and the dramatic perspectives afforded by a picture angle of 84¡ (61¡ when mounted on a DX-format body).

Features:
• A fast, single-focal-length 24mm lens
• Provides unequalled optical performance as a wide-angle lens with a maximum aperture of f/1.4
• High reproduction performance and high picture quality ensured with the adoption of two ED glasses and two aspherical lens elements
• Silent Wave Motor (SWM) realizes quiet AF operation
• Two focus modes are available — M/A (manual-priority autofocus) and M (manual focus)
• Rounded nine-blade diaphragm opening makes out-of-focus elements appear more natural
• Nikon's original Nano-Crystal Coat minimizes ghosting and flare effectively
