TH Swiss has announced the Irix lens family. The first product is a manual focusing 15mm f2.4 lens. It is available in Nikon F, Canon EF and Pentax K mounts and in two models: Irix Blackstone, which is fully featured and has a Al-Mg body and the Irix Firefly which is lighter. The lens offers an 110° FOV and focuses at 0.28m (0.92ft).

Both have threads for external filters and slots for internal gelatin filters.

The lenses will be available in Spring 2016 at a reported $600 for the Firefly and $780 for the Blackstone. Performance behind a dome is not yet known, but the focusing issue can be resolved by using a focus gear in a housing.
