New wide angle lenses from Irix might be particularly interesting for Pentax and Nikon users.
While Canon offers the about $2699 Canon EF 11-24mm f/4L (highly recommended,see my review), Nikon users have not had a high quality 11mm option. Pentax K1 users have a dearth of high-quality optics in general. So these new offerings fill in some blank spots.
I do not yet know if the optical performance is there, but as f/4 designs there is a lot of promise and they are on my to-do list for review. Available in “Blackstone” (high-grade build) and “Firefly” options.
