Even great for night photography
Edward1013, Carrollton, VA: Had this lens for more than a year now and it replaced the Canon 11-24mm f4 Canon. I just lost 1 mm in the wide angle side but gained in reduced size and weight. Surprised about the quality for night photography at 12 mm, f 4, 30 seconds and ISO 4000 with tripod. Stars showed not noticeable comma of at the edge of the frame using Sony a&RIII.
