Review Summaries Digitalrev dot com: Was incredibly surprised at the quality of the Irix and declared it is an excellent lens. Both of the Firefly and Blackstone versions are optically and mechanically very sound. Sharpness is fantastic, with distortion and vignetting extremely well controlled. There are no problems with chromatic aberration, and ghosting and flare is kept under control. Digitalrev said that they hope TH-Swiss will in future produce more lenses like these.
