All of a sudden my D300 has developed a side focus issue. Sent some samples into Nikon and they came back with the generic answer to switch to matrix metering or send it in for repair. Not happy with either answer! Can't take a macro shot with matrix. Guess I'll be focusing manually from now on.
Oh you're right JL, guess I got lazy after explaining the problem in such detail to Nikon.
The problem is with point focus, if I focus on the stamen of a flower, the sharp focus is off to the left. Clearly evident when viewing the red focus point box in Capture NX2. It's consistent with three different lenses. Tested with the camera on a tripod.
Exactly, I asked that question as well, they said they're just covering all the bases. Said to send it in for repair, and the very least a clean and adjustment. Think I'll focus manually for a while, till Nikon releases the D400.
Hi JL, I'm not sure I understand the first part of your question, the focus point moves fine in the viewfinder to where I want it to be. It's the focus itself that shifts outside of the focus point box, and oddly enough, it does vary.
It sound like you are using Dynamic area AF and the focus is shifting off of your selected focus point.
Does this happen with single point AF?
Does it behave differently between AF-C mode and AF-F mode?
One easy thing to try is to update or reinstall the cameras firmware.
I had a D300 develop an odd AF problem that I could nit figure out. I downloaded the firmware and reinstalled it in the camera (it works even if your current firmware is up to date) and the AF issue was resolved. It must have been a firmware hang up.
Cathy, I hate to say this, but I wouldn't expect much free help from Nikon with our "older" cameras. Sounds to me like the matrix metering suggestion was a way to get rid of you with something designed to placate those who don't know what they're doing. They want you to upgrade, or fork over bucks for repairs. Personally, I avoid all the autofocus issues by using my trusty old manual focus Nikkors, but if I had AF lenses, I would want them to AF, too.
Hi James, I totally agree, and found their response frustrating, especially since I spoke to the agent, explained the problem, and sent the sample frames to him. Just a quick response, to remove my problem from his in box.
If the suggestions here don't solve the problem, you could send it into Nikon for evaluation and to get a repair quote. In spite of it being an "older" camera, I'm sure they would be happy to repair it, if you want to spend the money. (If you do, perhaps the D400 will be announced the next day!)
Once you get a quote you'd be in a better position to pick an option, be it a new DX body, a good used D300s to tide you over or maybe make the jump to FX? (A D700 would feel right at home after the D300 if you don't want to go for one of the new FX cameras.)
Hopefully, though, one of these fixes will work for you (and we will just continue to wait for the D400).
I'm reluctant to send it in. A few years back, sent this back for a hot pixel issue, when I received the camera back the sensor was filled with dust spots, and the problem wasn't fixed. After sending it back a second time, the issue was resolved.
For all the folks waiting for the D400, I'm accepting bribes to send this in for repair, or to purchase a D700.
BTW Mick, do you ever sell any of your "old" cameras?
While not specifically addressing your focus issue, I have an issue with my D-300. See my thread on "Crack on the Control Panel Plastic Cover". In the course of considering options I did an on-line estimate using KEH's website. The estimate for a D-300 in good shape was $231. I was really suprised how rapidly prices have depreciated on a D-300 but probably expected. Bottom line it is not cost effective to have it repaired as the cost to repair may exceed the value of the camera. So it sounds like manual focus until you decide to upgrade.
Sorry to hear abour your focus issue. Assuming nothing physical has happened to cause sensor misalignment, have you blown out the focus sensor area of the camera. It is usually located at the bottom of the mirror cage. That area can accumulate dust from lens changing lenses. If nothing else it is worth a try.
HI Lyle, Love your screen name & Suki's picture. Thank you for the suggestion. I use a rocket blower every time I make a lens change, so it should be pretty clean in there. I'm a fanatic about sensor dust.
Try this procedure: As to Thom Hogan D300 book the last resort reset. Turn the camera OFF. Remove all power sources (battery, AC power adapter). Turn the camera on until the clock battery runs down (note that this could take a month or more) If you are in a hurry you can try leaving the camera on for only a few second, but this doesn't fully reset some of the internal parameters. Turn the camera back off. Put the battery back in to the camera or restore AC power. Turn the camera back ON.

Thanks Dave, good info to have on file. I'm traveing on Colorado now, and hope to have a few good tests to evaluate after the firmware reload. Then I'll try the reset. , http://kathycavallaro.smugmug.com/
