We already reported that the Canon EF 85mm f/1.4L IS USM lens has already been registered. And Canon will announce the new Canon EF 85mm f/1.4L IS USM Lens and three more lenses at the end of August, and this lens will NOT replace the current EF 85mm f/1.2L model ($1,899). The detailed specs and pricing info of Canon EF 85mm f/1.4L IS USM Lens are still unknown.
In addition, the previous rumor said the new Canon EOS M20 (M10 replacement) mirrorless camera will be announced at the end of August, 2017. So, Canon will probably announce the Canon EOS M20 mirrorless camera along with EF 85mm f/1.4L IS USM lens.
Stay tuned for more info.
