For the most part, no big issues until I put a Tamron 70-200 VC f2.8 on my D810 and then I began to see a general softness across all my pics. I went through the lens calibration procedure and found out that +15 wouldn't move the focus point far enough. I printed high-quality photos (29) of the Spyder Target and the lens, with pictures is at Tamron. They said that they could adjust the lens. As a last resort, they recommend that I send in the camera body with the lens(es) and they will calibrate the lens to the body. My problem is that I also use FX lenses on my DX D7100 so I am not of the inclination to keep sending in all my stuff to Tamron. In all honesty, the 70-200 had been repaired once by Tamron which is the starting point for the soft photos.... those prior to that were tack sharp. Sooooo, not sure if it is a Tamron build issue, or the repair guys missed something but I am expecting the lens back within 6 days and will post the results.

Thank you and the others for your responses. They were helpful. Not sure if I'm going to keep the Tamron. I'll be curious to see how you make out when you get the lens back.
