Nikon Z8 - Service Advisory

[Geoff_G]

i've seen at least one reference, but i didn't pay attention to the details so can't point you at it

Ditto. I was rather surprised when I read that.

All UPS to NY go into their Jericho, NY location. Most--go through the 'repair process' in this location. Some may require another pair of eyes and may be sent to Nikon's Melville location. Literally around the corner. This could be the reason for one Z8 taking a little longer than another that went into the shop the same day.

And it appears that the LA location is turning them around much more quickly than NY. I took mine to UPS last Tuesday -- June 27, and am getting it back tomorrow. 9 days total.

 

[Geoff_G]

Has anyone heard a specific instance of a camera and lens that was mounting fine, and has subsequently developed a problem?

I found it...Here is the start of the discussion..... #20

 

[Al Wyman]

It's finally back home. I shipped the camera to Nikon in NY (I'm in NH) on
June 23 They got it on Monday, logged it into the system on Tuesday and shipped it out on Friday. The sad part is that it was in UPS's distribution center
10 miles from my house on Saturday at 1:30 pm. I finally got it today, Wednesday. Nikon did their part as quick as could be expected, certainly no complaints about their turnaround

 

[Patty15]

They won't strike until their contract expires. Don't let your UPS packages travel past Aug 1st if there's a strike that's the most likely date.

I fear it will get bogged down. Mine goes to NY. I hear folks saying it takes longer there. With my luck, if I ship it in the next day or so, it will take a few days to get there, a few days to get checked in, then in the shop for however long that will take. August 1 is not that far away.

 

[gdecamp]

Mine says shipped today but still not available on UPS to track. They probably didn't pick it up yet so will check later! I'll probably get it back Friday if not it would be Monday.

Well just got an email from UPS mine is being delivered tomorrow! Shipped today, sweet!

Well mine is still in the shop (5 days+ now)....maybe I ought to make the drive and take it from the Jericho location to Melville...grrrr

No return call from Nikon Canada but an inane email entitled “Help is on the way” promising that they would email a shipping label. The same ”help” they promised a week ago…..

Just send the damn shipping label - what can be so complicated in that task that it cant done in a week….??

I contacted my dealer today and was told "if it's working OK, do nothing" - I asked for that to be ratified by the Nikon importer here in New Zealand, and I'm waiting on them. Mine's working A-OK with all lenses, all TCs and LM-NZ adaptors.

My Z8 worked with all my 14 x Z mount lenses, 2 x TC's and 2 x FTZs also but the Nikon exec told me to bring it in anyway. It is supposedly just 4 shims and 4 new (mount) screws. I would say there are 4 shims as they either fit between the four mount screws or the mount screws go through the shims to keep them in place.

I beleieve that is what you were told but this confuses me. Shimming the mount? How do they do that without changing the mount to sensor distance (a rather critically important dimension)?

Firstly, the mount is obviously too slim and hence why some lenses don't fit correctly. The shim just puts the mount where it is supposed to be. Would you rather it be too close to the sensor as this batch seems to be or at the correct distance?
Secondly, AF is off the sensor so is not as critical for mount to sensor distance and we are talking about a thou or so.
Also, my friend's Z8 had 4 shims and four screws shown on the work sheet. Unfortunately, my work sheet didn't show it but mine was the first that they did here in Oz.

Like I said, I believe that is what you were told. All I want is my camera back and working. But shimming the mount sounds like it changes the mount to sensor distance. Evidently shimming isn't changing it much if lenses still focus to infinity. Just a curious problem and fix....

And like I said, I was told but my friend's work sheet actually stated that there were 4 shims used. The work sheet seems decent enough proof to me. And as I also said, the shim just puts the mount at the correct distance. Maybe the first batch mounts were possibley machined a thou or so too thin and thus needed to be shimmed.

 

[Geoff_G]

I never questioned what you said or was told. I don't need proof and wasn't asking for it.
I was just wondering aloud how they shim the mount and keep the sensor distance correct.
Thanks and enjoy your cam.

 

[EricBowles]

There are a lot of photo products that use shims for precise adjustments. I've heard other reports that shims are used with the mount so this is possibly just changing the shims or the torque level applied to mount the mount and shims.

Good news finally - the status of my Z8 is not SHIPPING. No tracking yet, but should be here soon. That's great as I have a trip planned for next week.

 

[Patty15]

My concern is not what Nikon does to the camera, it is UPS. I do not want to ship my camera with a bunch of unreliable fools. I was waiting for a delivery yesterday of a parcel from UPS when I received an email telling me they couldn't deliver it because there was no one at home. I was there all day sitting 6m from the front door. They just never tried to deliver it. Will I send a 4.5k euro camera with these idiots- no.

I have had that experience with FedEx numerous times where I am in the US. When I questioned FedEx about it, basically that just means they got to the end of their day and didn't have time to deliver. I don't know how UPS pays their drivers but a FedEx driver told me they were paid by day so they won't work 5 minutes over their time.

I don't have any issues with my Z8. So do I send them in

This is true. I've had - twice now - packages on the FedEx truck for delivery only to have the driver go home before delivering it. And no, they don't pick up where they left off. I was lucky he was able to complete his route on the 2nd day my packages were "out for delivery".

Your NPS status surely helped. Hopefully mine follows suit this week.

I don't think shims are unusual in this application. The mount has to be dead square to the sensor or there would not be uniform sharpness across the frame. But I still have this hangup that changing the shims changes that distance....a distance which I've always understood is critical. Now, it could well be that the sensor mount has some sort of small adjustability to ensure all four corners of the sensor are parallel to the mount. In the end it doesn't matter, just the engineer in me wondering how that works.

As Lance said above:

So your camera should be able to focus just fine after the mount has been adjusted.

As Lance said above:

I was never worried about it being able to focus.

I have not read an answer that satisfies me but that's me. Let's move along and drop this - it's not important and it's OT.

I think, as @Lance B said, that the shims were necessary to change the distance to be in spec, for example if the mount in the recalled units was machined too thin.
