Pick the Irix Firefly 15mm f/2.4 if budget is tight and you can accept a slightly narrower field of view and a brighter f/2.4 aperture for low light. The Walimex Pro 14mm f/2.8 stays the better choice if you prioritize the extra 1 mm of wide-angle reach and are willing to pay more for it, despite its slower f/2.8 maximum aperture.
