[QUOTE="BackdoorArts, post: 109786, member: 9240"] As I asked previously, do you have the images on your card so you can check them in the camera and determine if the focal point shifts? When you're operating in AF-A or AF-C mode then your point is dynamic, and it's going to shift. You want static? Put in in AF-S. The "real world scenario" you're painting tells me you're getting exactly what you're asking for. A constantly adapting focus target accompanied by a razor thin depth of field. AF-C is fine, just reduce the number of focus points, or at least 3D, and I suspect you'll see some change for the better. In certain scenarios AF-C can get real aggressive. Custom menu option a3 will allow you to turn focus lock on and off. How's it set on your camera? If it's off that may exacerbate your problem. As for keeping the receipt, Nikon tells you to do it as well, and says that they may require you to provide it with warranty work. If you bought the lens from Amazon, B&H or another big retailer you may be able to view and reprint your receipt from there provided you did it using a user account on their site. I can go back a couple years with Amazon. To me it's ballsy to expect a manufacturer to service a product without one, particularly given how often things get sold "as new, with warranty cards" on eBay. [/QUOTE]
