First Choice for Portrait & Close-up Beauty
Its high speed and the unique aesthetics of its depth of focus make this telephoto lens the first choice for portrait photographers. The angle of view is 27 degrees. It highlights the main body while avoiding the suffocating sense of space compression caused by super telephoto lens.

Smooth Bokeh with Fast F/1.25 Maximum Aperture
Extremely fast f/1.25 maximum aperture affords notable control over depth of field for selective focus shooting, and also benefits handheld shooting in difficult lighting conditions. The smooth transition between the focus object and the bokeh creates a dreamy picture with an ideal depth of field and fascinating background blur.
