Review: IRIX 11mm f4 Blackstone (Canon EF Mount)
When the IRIX 11mm f4 Blackstone came in for review, I tried to figure out what I'd exactly do with a lens like this. It's super wide and has full frame coverage. It's too slow to really work effectively for astrophotography, but it is surely good enough to use for a day of fun walking about in Brooklyn. thephoblographer.com »
