Sigma 45mm f/2.8 DG DN lens, Sony E

Sigma 45mm f/2.8 DG DN - Sigma's ”normal lens” for mirrorless cameras

The Sigma 45mm f/2.8 DG DN is a normal lens designed for direct mirrorless photography and is ideal for still and video photography. The size and weight are typically moderate for DN lenses. The Contemporary series lenses are typically pleasant in terms of background softness. The three-dimensional impression is also strong thanks to good bokeh shift. For more information on bokeh shift, please contact From the experts on light leakage. The closest focusing distance is a comfortable 24 centimetres.

Full-time manual focus override is available, but the lens has an excellent stepper motor for smooth and fast autofocus. It's remarkably quiet, and the face/eye detection is excellent. Background softness is thanks to seven rounded dimmer blades. Naturally, a backlight protector is included to protect the front element and prevent reflections from stray light.

Optical formula The Sigma 45mm f/2.8 DG DN lens has been designed with good solutions to prevent various optical distortions and errors in your images. The three-dimensional impression is very successful. The maximum aperture of f/2.8 is sufficient for most lighting situations.

The bayonet is brass and there is a rubber ring at the base to prevent moisture from creeping into the mechanism. Almost pro level glass all in all. The other option is then to go a little wider and larger 35mm Sigma.
