About Nikon 14-24mm
What you should know about this lens:
• Optically optimized: The Nikon 14-24 is optimized for edge-to-edge sharpness thanks to two ED (Extra-low Dispersion) and PGM aspherical elements, which control chromatic aberrations and improve sharpness and contrast at all apertures. Nano Crystal coating reduces flare and contrast.
• Fantastic focus: The internal focusing mechanism can focus as close as 10.8 inches at 24mm. The Silent Wave Motor (SWM) is virtually silent, a benefit for videographers, and ultra-fast.
• Rugged build: The lens is sealed against dust and moisture
