Sigma 12-24 on D700
May 29, 2010

Hey guys, I just got a hold of a Sigma 12-24 and was quite disappointed by how soft the corners are at 12mm. I expected some corner softness, but they are really blurry. I mean, REALLY, quite blurry. I mean ... well you get the picture.

Perusing the web, many mention the blurry corners at 12mm, but some don't. I'm wondering, has ANYONE had a sample of this lens with crisp corners at 12mm (at ANY f stop). I realize optical compromises are probable at these focal lenghths (which probably explains why Nikon only goes as low as 14mm) but just wondering if the lens I have is as good as one can expect.

BTW, it's still a great lens, even if flawed at 12mm.
