Boomstrike (03.18.10, 12:03 AM): 22 MM !! Kyle (03.17.10, 10:49 PM): My guess is 17mm. Luis (03.17.10, 10:31 PM): I think it is 50mm lens with a full size frame camera. Am I right???? James McQuiggan (03.17.10, 7:06 PM): I got to use my first 17-24mm lens last week and with it seemed close to what I saw with my naked eye. I would have to say 15 to 17mm? Robert (03.17.10, 6:14 PM): Id say 35mm? Iwander (03.17.10, 2:46 PM): Think how wide the field of view is, I would guess 2 to 5mm... I will have some vignetting and barrel distortion after some Guiness tonight.. Happy St Pattys day all!
