Are you a professional portrait photographer? The Sigma 105mm f/1.4 DG HSM Art Nikon is the one for you. The lens is suitable for Nikon SLR cameras with an F-mount. You can create a natural bokeh look with the maximum aperture of f/1.4. This will separate your subject from the background. You can use this in portrait photography, for example. You have a lot of control over the focus point. The large filter size of 105mm brings a lot of ambient light into the lens. Combined with the large opening of the aperture at f/1.4, it allows you to take clear photos in dark locations. Thanks to the special coating, the lens is dust and splash proof and easy to clean. That's why you can use the lens in bad weather.
