[QUOTE="BackdoorArts, post: 121896, member: 9240"] The "Focus Issue" seems to be that a large proportion of the D7000's came out of the factory with a default calibration that reveals itself as a backfocusing issue with most lenses. Is this a "problem"? Yes. But it's correctable, and for any serious photographer, if you own a camera that allows you to calibrate focus for your lenses, not checking that calibration and setting it is akin to not checking the oil in your car. It'll still run, but one day it might bite you. I have the SpyderLensCal that was mentioned and it's an awesome tool for this, but there are simpler methods to be used. This topic has been discussed several times in this forum, so a little hunting will yield links to blogs showing you how to do it with a chart you can print on your own, or a ruler. Here are a couple that talk about the D7000 specifically. It took me about an hour to do 6 lenses and I don't have to think about it any more. It's the first thing I did when I got my D600 and D800 as well. The D7000 ran consistently back between -8 and -12 for most lenses. I looked at that and set a default of -10 for all "unknown" lenses.

There were reports that the D5200 exhibits the same type of focus offset between the two systems used (thru the lens and LV) so it may be inherent to the focusing algorithm and not a "camera issue".
