I've had my D7000 for over 10 days now. I have been riding a roller coaster of excitement/disappointment. Lately more excitement, as I have tried to follow the advices from other threads in focusing, camera holding, and more important, attention to detail in the settings of the camera. I also got the "Digital Field Guide" and continue reading.
Now, my two prime lenses (35mm 1.8, and 105 mm 2.8 micro ), have worked great from the get go. The 18-105 kit only so-so.
In reviewing my settings I noticed that the AF fine tuning values were set at to ON at level 6 as default. I changed that, first to value ON,0, then to off. I am not clear if I improved or hurt the end result, as the changes appear subtle.
Unless Nikon is taking the time to bench test every kit for fine tune focus before it is boxed, the default setting for AF fine tune should be off. Without careful and meticulous bench testing it would be hard to guess if a particular lens would need calibration and to what extent.
It appears you may have gotten a camera that someone else determined had a defective AF system and returned it to Best Buy for exchange. Depending where you live might mean a difference, but where I live once an item leaves the store and shows evidence of the box being opened and the product put through even minimal use, it cannot be resold as new if returned to the store for any reason. It should have been sold at a discount as an open box unit if this is truly the case, or returned to the manufacture as defective. Of course proving they did that could be problematic at this point.
AF fine tuning should have been set to 0. Off is probably best. You can actually enter a value for each lens, and each lens should be set to 0. Probably what happened was someone bought the camera and thought it was not sharp. It could have been a problem with their lens - or the user.
Generally the D7000 is pretty good and should not need fine tuning. It is an advanced feature that you should only use with excellent testing technique - otherwise you make thing s worse.
Thank you all! I actually did not follow advise, and bought a 2-year "black tie" plan that covers for damage, batteries, etc... So, for now, I am not going to take any risk. I had to save for the camera, and have been putting a lot of efforts in learning how to use it so I don't get so many blurred pics. I am going to Best Buy tonight, and just exchanging it for new one.
I followed advise. Got a new D7000. It is a like a complete different camera!!! My pictures a 1000% better! Finally, I was able to take casual pics of my kids without having to stop and think too much, or wonder "Did I get it this time?" I am going to start uploading pics!!
Great to hear your good news! My D7000 works flawlessly and is tack-sharp with eveything I put on it, right out of the box. Yours should be too. I think I like it more than any camera I've ever had, and I've had a lot! Cheers,
