I had a chance to play around with this today and found that some of my lenses needed to be adjusted. My methods were far from scientific, just quick focus charts/tripod and some water bottle tests. They seem to work pretty well. My question is, if you find that you need to Fine Tune a lens, does it mean there is a problem with the lens (or the body)? Should I contact Nikon and have them take a look? I have never sent equipment to Nikon, so do they also use the Fine Tune feature to adjust the body/lens or do they have a different method? I guess in an ideal scenario, I would have preferred the combinations to work PERFECTLY without any adjustment. :smile: For those that have multiple camera bodies and have Fine Tuned lenses, do the adjustment levels vary between the bodies (example, a lens might be +5 on one body and is +10 on another body)? I am just trying to get a clearer understanding on this. Thanks everyone.
