Ed means optical distortion. Nikon lenses have been known for their low distortion levels, making them a popular choice for photographers who want to get the most out of their images.

What is ED?
ED stands for “extender drive”. It’s a mechanical or electronic function that helps you control the amount of light that enters the lens through the aperture. When you press the shutter button, the camera takes a picture by capturing a series of light rays that come through the lens and hit the sensor. The camera extracts the image data from these rays and creates a digital picture. If you’re using a digital SLR, the lens aperture is controlled by the camera by opening and closing the lens iris.
What are the benefits of ED lenses?
One of the main benefits of Nikon’s Extra-Low Dispersion (ED) lenses is that they produce superior image quality when used with Nikon digital SLR cameras. With an ED lens, the light waves that pass through it are slightly misaligned, which creates a more accurate image. This, in turn, yields crisper, more detailed images and smoother video output.
How can you tell if a lens is ED?
ED lenses are those with a diaphragm that has been specifically designed to reduce the amount of light that is let into the lens. This can be helpful for reducing the amount of noise that is created in images, and can also be helpful for reducing the amount of distortion that is seen in images.
What are some popular ED lenses?
There are many popular ED lenses, but some of the more common ones are the Nikon 70-200mm f/2.8G ED VR II lens, the Nikon 10-24mm f/3.5-4.5G ED lens, and the Nikon 14-24mm f/2.8G ED lens.
Why do some photographers prefer ED lenses?
Ed (Electronic Diaphragm) lenses are a type of lens that uses electronic diaphragms to control the aperture instead of a physical diaphragm. This type of lens is more common on digital SLRs as it gives the photographer more control over the light that is entering the lens.
ED lenses are generally more expensive to produce than other types of lenses, but they offer certain benefits that make them desirable for some photographers. For example, ED lenses are typically faster to focus and shoot with, and they can offer greater control over the depth of field. They can also produce images that are sharper and with more contrast than lenses with a physical diaphragm.
Since Nikon lenses are often calibrated in terms of exposure, it can be difficult to determine the exact meaning of “ed” when referencing a Nikon lens. Generally, “ed” stands for “exposure,” and is a measure of how bright or dark a photo appears.
