But I don't have enough time because I'm about to go down to Florida for a week. In a nutshell - Extremely sharp up to f8, sweet spot at 5.6. - Extreme Corners slightly muddy till 5.6, but at 5.6 they look great... much better that most WA lenses. - Extremely flare resistant - Haven't seen ANY chromatic abrasions yet - very little purple fringing - Color and contrast are excellent - focuses faster and better (better means low light focusing it is not more accurate) than the 28-75 2.8 even though they're the same aperture - front focusing (badly) on my 30D. Needs calibration. Noticable at 2.8 and f4, effects not noticable by 5.6 So here are a few pictures from my trip to NYC. I took around 500 pictures with this lens over 5 days, it never left my camera even though I brought other lenses. Roughly 80% of the shots are at 17mm. Also, if you're wondering, yes I did go to B&H while I was there (I walked from B&H (34th street) back to my sisters place on 112th street), but they were extremely busy. I was not overly impressed by the knowledge of their employees however. I told a guy I wanted two neutral graduated density filters... a 2 stop soft and a 3 stop hard and he said "well you can just stack two because I don't think we have any of the "other ones" you're talking about". Their prices also greatly deviated from the catalogues they had in their store. I did however buy a Bogen ballhead though.... a $100 one. EDIT: Ohh yeah, and on the two days I went to central park I had SHIT light to work with. If you're saying to yourself "A CP would really be good on some of these shots" I completely agree with you. I bought a Hoya Pro1 digital 67mm CP on ebay tonight for $73 shipped. I did a lot of research. A lot of people recomend B+W or Heliopan, but the Pro1 line from Hoya is supposed to be extremely good as well. B&H wanted $145 for the same filter.
