mike_spirito1 Posted January 10, 2015 Share Posted January 10, 2015 <p>I have 2 Nikon d750's. Also I have a new Sigma 50mm art. One one camera its tack sharp. On the other camera I have to do a micro adjustment of +8 . Should I be worried about this?</p> Link to comment Share on other sites More sharing options...

ShunCheung Posted January 10, 2015 Share Posted January 10, 2015 How about your other lenses, do they also need AF adjustments, perhaps different adjustments, on the two bodies? +8 seems to be within normal range. I have a 28mm/f1.8 that needs -18. That is a bit off. Link to comment Share on other sites More sharing options...

ShunCheung Posted January 10, 2015 Share Posted January 10, 2015 Mike, there is an old saying: if it ain't broke, don't fix it. If you have a body on which every lens requires +19 type adjustment, maybe I would send it in for calibration. I am not sure there is anything to fix in this case. Any unnecessary adjustment may make it worse and shipping may cause some issues. Link to comment Share on other sites More sharing options...

dan_brown4 Posted January 16, 2015 Share Posted January 16, 2015 <p>I doubt Nikon would do anything to solve a Sigma lens focus problem.</p> Link to comment Share on other sites More sharing options...
