Wondering what all those abbreviations mean in the names of Nikon lenses? My Nikon Life made this 5-minute video that shows you what all of the different elements of Nikkor lenses do and explains how they how they work.
Here are all of the different elements that you may recognize from your own Nikkor lenses (if you’re a Nikon shooter):
Fluorite lens: Allows for a lightweight lens with better capabilities for chromatic aberration correction.
Aspheric ED glass: Corrects for chromatic and other lens aberrations. This is a glass element that combines both the ED lens and aspherical glass into a single lens.
Phase Fresnel lens: With superior chromatic aberration reduction, this lens technology also caters for lenses that are smaller in size.
Nano Crystal Coating: Reduces ghosting and sun flares to allow for clearer images.
Fluorine coating: A highly durable coating which works to repel dirt from the lens.
Vibration reduction: Extremely useful technology that compensates for camera shake, allowing longer exposures without added blur.
Silent wave motor: Silent and fast autofocus.
Electromagnetic diaphragm: Aperture control at a fast speed with high accuracy.
Lens barel mechanism: The barrel controls complicated movements.
Dust and drip resistant performance: Weather sealing to prevent dust and water from entering the lens.
