Review: Irix Firefly 15mm f/2.4 by Northlight

Keith over at Northlight Images has completed his extensive review of the Irix Firefly 15mm f/2. 4 lens. We seem to have an abundance of fast ultrawide lenses to choose from now. Canon, Sigma, Rokinon, Zeiss and now IRIX all offer competent lenses at different price points.
