Lens Irix 15 mm f / 2.4 Firefly for Canon EF

Irix Firefly 15mm Ultra Wide Angle Lens for Canon Magazine reviews: Digital Camera World - 5 Stars "Great Value" "The Irix 15mm combines impressive handling and build quality with superb image quality, at a bargain price." ePHOTOzine " The Irix 15mm f/2.4 lens is a powerful photographic tool. This new lens from Irix lifts the performance for such lenses way beyond the first early 1970s offerings and gives us a lens that is free from flare, and very sharp. This Swiss design is an excellent one, built in Korea to very high standards." DigitalRev "I was incredibly surprised at the quality of the Irix and can easily say it is an excellent lens. Both of the “Firefly” and “Blackstone” versions are optically and mechanically sound. Their sharpness is fantastic, with distortion and vignetting very well controlled. There are no problems with chromatic aberration, and ghosting and flare are are kept in check. I really hope that TH-Swiss produce more lenses like this in future. The Irix 15mm f2.4 is produced for Canon EF, Nikon F and Pentax K mount."
