Its system is composed of 14 lenses and 9 groups, it has two glasses and three spherical lenses. Its weight is approximately 450 grams, therefore very light thanks to the high quality plastic materials with which it is made. Nikon AF-S DX 10-24mm f/3.5-4.5 G ED is equipped with an internal focusing system, this means that the length of the lens barrel does not vary during focusing and the front part does not rotate. With this device you will have two types of focus available: autofocus with a manual priority or manual focus. This lens is capable of offering very good image quality, very good depth of field, rather short working distances, a wide FOV range and dramatic perspectives. The only flaw, if you can define it that way, is that it has excessive softness in the corners especially when used at 10 millimeters.
