Hey all,
I posted here a few weeks back about some really bad CA with many of my lenses (with the exception of my kit 18-70). Long story short, my CCD was replaced for other problems and 98% of the CA disappeared. Needless to say I'm a happy camper.

I just got a used 28-70 f2.8. This lens has great potential with the d200...However, I'm seeing CA at f2.8 through f4. It disappears from f5.6 on.

The problem I had before with what I thought was CA actually turned out to be sensor blooming. This looks slightly different and more representative of real CA. I've tested it in two separate scenarios, one outside with clear skies behind some dark branches (it fairly bad there) and my standard indoor test against a strong light source (which is a great indicator since its a consistently controlled lighting situation) which came out not so bad.

So here's my question: For those that have this combination, do you see this happening? Secondly, is there anything Nikon can do to "calibrate" or adjust the lens?

Thanks.
