This is about left/right AF points and appears only to effect wides ( Jul 05 12 08:47 am Link Hmmm... thanks the for the heads up. Wonder who is going to send it in for Services?

It does of course assume that your lenses are equally sharp across the frame. Jul 05 12 12:31 pm Link Seem that similar issue was present from the start: And the Nikon D800 autofocus saga continues (with some comments on specific lens performance) Jul 05 12 12:37 pm Link Jeffery Williams wrote: photoimager wrote: Recently, I had a few situation during the shoot that neither the far right and far left can focus. I had to resolve it by using the center focus on the view finder. This is odd, but I did not pursuit after. Not sure my problem is the same as this one. Any one know?

Jul 05 12 01:33 pm Link Jeffery Williams wrote: Using the center and right AF points the images was primarily clear (not as sharp as the D700 to my eye but clear). When I used the far left AF point the image was very OOF at the left and soft over the rest of the image. Jul 05 12 01:39 pm Link There are more detailed descriptions of the fix elsewhere. From what i have read it requires that the camera be connected to calibration equipment (so it's not a firmware fix, exactly), measured very accurately, and the results written into the camera. So you do have to send your camera in for the fix, but they don't replace any parts. Jul 05 12 01:53 pm Link Jeffery Williams wrote: I've outlined the procedure here. Jul 05 12 09:22 pm Link It is for reasons like this that I tend to wait six months before I pick up a camera after it is released. They all seem to have teething problems when they are new that get shaken out in the first few months.

Jul 06 12 05:56 am Link I am wondering how D800's assembly line. It would be that one or two of their assembly line got affected by this AF alignment. Jul 06 12 06:10 am Link I was having focus issues on mine. Not sure what the culprit was but I took it to the retail store and they agreed. Sent in for repair currently. I wonder if this was the problem... Jul 06 12 05:06 pm Link |
