VerdictOn our FX test camera, the lens did not really show impressive performance, however on DX the results are a lot more solid and convincing.
Center and border sharpness is generally very good, but there's a visible drop in sharpness wide open and the extreme corners need smaller apertures to show good resolution.
Vignetting and CAs are very low and not really field relevant, except maybe CAs at 24 mm. The only real issue of the lens is it's unpleasing bokeh. If your intended primary usage is to shoot portraits or seperate the main subject from a blurred and smooth background, you should probably look elsewhere. However, if you can live with or work around this issue or if you shoot stopped down mostly and just need the speed to have more reliable autofocus, the lens is a rather attractive option for a DX camera.
