An excellent wide angle
Luis M. on 09/04/2019 (Automatic translation) The Irix 11mm f / 4 Blackstone conveys a feeling of robustness and firmness that is appreciated. Despite being manual focus, the infinity click is very useful, leaving only the aperture calculation for short focus distances. With a Canon 5D Mark IV the quality it offers is superlative, having some chromatic aberrations easily corrected in post-editing, it has great sharpness. For this price you have an exceptional wide angle.
