Digital Camera World Verdict

This lens for APS-C format mirrorless cameras combines an ‘effective’ focal length of around 35mm in full-frame terms, with a fast f/1.4 aperture. Better still, it packs these favored features into a compact and lightweight build. The net result is a lens that’s ideal for street photography, environmental portraiture and for shooting indoors, as well as for grabbing some nice bokeh for close-ups. It’s simple but highly effective and good value at the price.
