I recently bought a Tokina 12-24 and I have to say I'm less than happy with the overall image quality. I have done a comparison with my trusty old Nikkor 18-35 and the Nikkor wins big time. I know the 18-35 isn't the greatest, but stopped down to f9-f11, it's no slouch. In the same range, I was expecting better from the Tokina (compared at 18- 24mm and f10) based on what I've read. These are on a D2x, BTW. So, the question is, do I have a bum copy of the Tokina, or is that as good as it gets? B&H is closed till tomorrow, so I only have a limited amount of time to decide if I want to keep it. My feeling at the moment is that it's going back, I'm more wondering if I want to try another one or just forget it altogether. I'm not talking about the distortion, it's the sharpness. the middle seems ok, but the edges go soft fast and it doesn't look like the DOF (which should be huge) makes it any better.
