Greetings, I recently purchased a used D700 and it seemed to have focus issues. So, I sent it to Nikon for service and cleaning. I just got it back and it still seems to have the issue, if not even worse than before. Problem: Camera seems to focus correctly when the focus point is in the middle. However, if I move the focus point anywhere else, on either side, the camera thinks it's in focus, but the result is not in focus. I.e. when I move it to the right most of the time the entire photo is out of focus. I'm not new to photography and I don't seem to have this issue with my D300s. Have any of you had this issue with your D700, and have any of you sent your camera to Melville, NY to nikon, and what has your experience been like? Thanks in advance.
The three center columns of 5 sensors (15 total) are cross type sensors that are rated for lenses with a maximum aperture of f/5.6 or faster. The remaining 18 sensors on each side are not as sensitive as the middle 15.
Thanks for the replies. I tried posting a few shots but seem to be having an issue getting them to upload. Will attempt again later tonight.
I just went out and did another couple of tests this evening after sending some samples to Nikon. You'll love this... the reply the young lady sent me back was "none of them are in focus." Uh yeah, I know. That's the freaking point. What my test this afternoon showed was when I used any of the 15 cross sensors, the camera would focus. Anything outside of the 15 cross sensors and the focus would shift just out of focus and the shutter wouldn't release because the camera recognized it wasn't in focus. Happened consistently on both sides. So, I moved closer to my subject. When I did, The camera would exhibit the same characteristics with one exception, even though the the focus point (outside the cross sensors) was still out of focus, since I was closer the camera thought it was in focus (little green light was on and the focus beep went off and the shutter would go off. Totally out of focus.
Strangest things I've seen. Appears the non-cross sensors are out of calibration. Yes, they may be a little less sensitive, but this is ridiculous. My D300s has the same focusing system in it. I've done the exact same tests with the same lenses, and don't have these issues.
By the way, you asked about the lenses I was using: 24-70 f.2.8; 70-200 f/2.8, and today I used a new 16-35 f/4. Pretty good crop of lenses.
Thanks Marty. Oddly, I sent it in a few weeks ago to have the focus looked at. I guess I wasn't specific enough and they just did a general look see. This time I'm being specific with photos i'm sending.
Yes, they said they would pre-pay for me to ship it back. I hate to ask them to rush it again as I want it right. A little disappointing though as I'm supposed to go to Washington DC next week with 60 WWII vets, my grandfather being one of them, for a trip to the WWII memorial. Charter flight, police escort, the works. Really wanted the D700 and 16-35.
Oh well, I guess I'll take my D300s and 17-55 f/2.8
>I hate to ask them to rush it again as I want it right.
Typically when a repair is rushed, it's from the standpoint of how long it takes to get the camera into the technician's hands, not how thorough the technician will be once he has it. I wouldn't worry about asking them to rush it, especially under the circumstances.
With your additional documentation and since your problem isn't intermittent, now that he'll know what to look for, the tech should be able to verify the symptom quickly.
Don't fret if the D700 doesn't make it back in time. Your being most familiar with the D300s, you'll capture great moments and not have to worry about fiddling with a new camera. Enjoy your trip and, please tell your grandfather how much his sacrifice means to us. I'm looking forward to seeing pictures of him at the Memorial.
for this trip I hadn't thought about it. so, you bring up a good point. Rented a D4 in Hawaii when I shot the Hawaii Five 0 sunset on the beach premier. could rent a D800 for the day... may look into that tomorrow. thanks fro jogging my brain.
