Heavy. Dim corners and edges. No support for filters.
Indoors in dim lighting conditions, outdoors at dusk and at night, I never once wished for a tripod or flash knowing I could shoot wide open and capture the moment without resorting to outrageously high ISO settings. This lens showed its true colors every step of the way.
Invite the sun to set and turn down the lights – this lens has no fear of the dark. As of review time, the Sigma 20mm f/1.4 DG HSM Art Lens has a wider aperture than any lens wider than 24mm. With this unique tool in your kit, freeze action in low light situations calling for a wide angle of view.
Heavy, but good quality.....came with dock...as yet unneeded!
