Adobe has updated Lightroom 5 to version 5.7.1 and now includes support for Sony A7II RAW files, as well as several new lens profiles. The update also addresses a bug fix for Samsung NX1 files.

I hope the update includes a lens profile for the Canon 400mm f/5.6. I’m beginning to think they’ve never heard of the lens.
