"The Irix 11mm f/4 is an excellent ultra-wide-angle prime lens that delivers very good image quality. Sharpness in the centre of the frame is excellent throughout the aperture range, even wide open at f/4, as are the edges, with f/5.6-f/11 producing the best results. The Irix 11mm f/4 is a pleasure to use, thanks to its superb build quality, smooth focus ring and hyperfocal scale." Read full review |
"What an exciting lens the Irix 11mm f/4 Firefly is. It opens up a whole new world of creative possibilities in a well-made, well-designed package that delivers the image quality. It will not be for everybody, perhaps because of the ultra-wide style of the images, or maybe because of difficulties using the manual focus system, but if the lens appeals to the individual photographer's creativity then it will be a rewarding experience."

"The Irix 11mm f/4 Blackstone is a well made and competitively priced ultrawide lens for full-frame Canon, Nikon and Pentax DSLRs. Image quality and handling are very good, but if our test sample lens is anything to go by, you may have to make some exposure corrections to compensate for the lens's imprecise aperture diaphragm control."

"The Irix 11mm is a fully manual lens. Its focus rig is large, well dampened and fluid. Its range allows precise adjustments at close distances, and easy corrections at longer distances." Read full review |
"In terms of image quality, I was pleasantly surprised by the optical performance of this glass. The sharpness in the center is very good even at the widest settings, while the corner resolution improves significantly at f/5.6. Have a little bit of Vignetting and chromatic aberration at f/4 but they also decrease when stopping down the aperture." Read full review |
