EISA DSLR LENS 2017-2018
The SIGMA 135mm F1.8 DG HSM | Art is an extremely capable performer. The sharpness is better at its maximum aperture of F1.8 than its competitors are when stopped down.
There is simply no reason to not use this lens wide open. SIGMA has managed to make the autofocus fast and accurate, which is impressive for such a bright lens, and the wide aperture creates a particularly beautiful background blur (bokeh).
