 p.1 #3 · Advice wanted--sigma 15-30, Sigma 14 (and Canon 17-40L) | |
Yes, I am using the 5d mk II. I looked at photozone.de, the center resolution numbers for the sigma 15-30 are very high, so that's one of the reasons why it appeals to me--although obviously, everyone will point out that the numbers are just theoretical, the proof is in the pudding, as they say. But I came across some image comparisons at the 16-9 website, and it looked good--better than the 12-24, which is kind of why, as you suggested, I was figuring the 5d mk II might really outresolve the 12-24. But yes, I will probably be shooting at f8 or 11, so no problem with stopping down (I assumed I would have to anyway with those lenses). Although that seems like it is the optimal range for the 15-30 also. The 14mm, since it is a prime, in theory should have pretty good resolution, but some of the images I have seen online are not so sharp--maybe what you are really getting is the 2.8 rather than the sharpness. Anyway, please, any real world experience you have had with any of these lenses, let me know--you know, one problem I have when I look at the online reviews is there are people out there who are wiling to sing the praises of anything, so it's hard to get a sense of context. I think I could probably shoot a photo through the bottom of a Coke bottle, and there would be someone, somewhere, who would say, "wow, sharp as a tack!" So like I said, any real world experience, or if anyone would like to share some photos, and tell me what they found positive or lacking, that would really be appreciated.

Of course, I still lust after the Nikon - it's just so dang good.
