Why I also think I have a D2x focus issue

HI David

I think that you do have some motion blur, however, the biggest issue is indeed the back focus.

I shot a large beaver late last week swimming towards me...I was solid on a tripod and I got exactly the same reults.

Rons camera is back at Torrance and mine will arrive there today.

We're hoping they get this figured out.

By the way...I did receive two e-mails yesterday, bitht from NPS members, one in CA and one here in the States sying that Japan was working on this and there should be some resolve shortly. There were no specifics unfortunately.

I feel fairly certain that I am experiencing the "back focusing " issue as well. The interesting aspect that I am seeing is that it seems to occur on stationary birds and small animals as well. I am not certain the focusing sensor is aligned with the outlined focal point box in the viewfinder. I can sometimes adjust the positioning of the subject just above the box and achieve focus. I intend to wait until I see this sort itself out before attempting to send mine in. I still have my trusty D2H.

I haven't said anything before about it but I think I'm in the same boat as you, I'm not getting the results I want reasonably often. It is complicated by the Sigma 800 being a bit hard to focus on the D2H as well. But I got better reuslts on the D2H then the D2X that is for sure.

The 300mm 2.8 AF (older version) I got gets excellent results by the way when it comes to sharpness.

I get this feeling it only comes from AF-continous, I get better results with AF single focus.

So how do we test properly for backfocus issues? There is a testing thing for the D70 from this guy in New Zealand. I tried with the D2H and it showed frontfocus on my D2H. what do you guys think about that testing method applied for the D2X?

I'm not at all convinced that a test chart will help you. I can get really great stuff inside of 10'. From 10-15' I can begin to see the random focus issue and out past 25' it is easy to see.

I've never shot a test shot before, but aren't they used up close?

Maybe if someone through it up in the wind and I shot it floating by.....

Kidding of course

 

one thought that comes to my mind is the VR feature on the new lenses and if it has any bearing on focus. I doubt it but it may be something to experiment with.

 

Dave

I had the same issues with the 200-400 as I do with all other lenses.

On the 200-400 it made no difference relative to the focus issues with the VR either on or off.

 

rules out the vr issue.

 

David et All

Well...

Nikon called and apologized that they would not be able to have my camera back to me tomorrow as we were looking for a Saturday delivery.

They have been working on my particular camera since Wednesday and they are unable currently to correct the focus issues.

I of course asked that they replace it once I heard this and I was told that replacing it with any of the current cameras would not resolve the issue.

????????

 

Sorry.

Re: David et All

Jim,

Seeing that Nikon told you that replacing it with the current cameras would not resolve the issue, tells me that they believe that most of the cameras sold has this problem. Maybe not, but I was just reading between the lines.

I'm waiting like some others here have said to turn mine in because I would rather they figure out the problem first. Since I don't use the camera on a professional basis, means I can wait.

Thanks for letting us know Jim.

 

No Clue

Well...I have no clue as to whether they have a clue...does that make sense?

Paul Frye (A shooting buddy of Ron's) did post on DPR a short while ago that he and Ron went shooting yesterday and that after Ron reviewed the LCD of some shots, he felt that his camera might be working better after the 2nd repair...although he had not yet had the opportunity to look at them on the computer.

Time will tell I suppose.

Thanks god it's gonna be a cruddy weather weekend.

 

what that tells me is that they all do have this condition, some just have not seen it occur yet. Jim I know you were operating a friends camera and did not experience it, is that right?
I contacted Nikon today concerning mine but have not been invited to return it yet, which is just as well as i have a photo vacation in a week. May be using the d2h for the fast stuff.

 

Dave

I did in fact shoot one for a morning and it appeared as though it was perfect to me.
