It has competition from the likes of Nikon’s AF-S 105mm f/1.4E ED, but it is £500/$635 cheaper. Canon users who’d like a premium portrait lens that fits the gap between the superb EF 85mm f/1.4L IS USM and the old EF 135mm f/2L USM are likely to be intrigued by it too, plus it is soon to be available in E-mount for Sony’s range of A7-series full-frame mirrorless cameras.
