I wonder if the Battery recall has anything to do with the supply issues for the D800.

I have an issue with the Mirror. I noticed at the weekend that about 1/2cm up from the bottom of it and about 2cm in width centered there is what looks to be a hairline scratch. My previous Nikons did not have anything like this. I spoke to Nikon and they grabbed a D800 whilst on the phone with me to discover theirs had exactly the same mark on it.
I don't see how the mark could be made by the camera so it looks like a manufacturing issue to me. Obviously it doesn't affect the photographs and it's not noticeable through the viewfinder. If it is somehow made by the camera though, potentially it could get worse.Out of curiosity I checked my D800, and (*cue the trumpets) it does have a scratch/rubbing mark in the same spot. Since it's somewhat uneven, I am leaning towards a manufacturing defect, rather than something that's supposed to be there.
Which means my camera not just needs glasses on the left side AF sensors, disregards focus priority settings, has a battery that could potentially explode, it also comes with an "etch-a-sketch" mirror.Posted 1 year ago # -
I think the core issue with the D800/D800E is one of design (or lack thereof).
With all of Nikons engineering expertise,
couldn't they have figured a way to allow for the AAF to be inserted into,
or removed from, the optical path via a user control,
rather than produce two separate cameras? This "best of both worlds"
design would have guaranteed the D800 a spot in the DSLR Hall Of Fame.Posted 1 year ago # -

So does that mean the the people without the scratch on the mirror have a faulty one?? lolPosted 1 year ago # -

Personally I think it looks too uneven to have been part of the design and that they have probably decided it didn't have any effect on the use of the camera and so won't do anything about it..

I completely agree with you Paul, they should have made it a switch to allow the user to use or not the AA filter...If I am not mistaken, the AA filter is at the level of the pixels. Both the D800 and D800E split the image into different paths, then the "E" brings these back into the same Pixel, while the non "E" with the AA filter, shares a part of the image across multiple pixels. And this is what gives information to the software which eliminates moire patterns. And of course this is the basis for the argument about the ultimate sharpness. If one does not split the image so as to eliminate the moire, then it must be sharper.
In any case as this is occurring at a near microscopic level on the sensor, there is not at the current time a practical way to "remove" the AA filter as it is part of the sensor.
Ernst Leitz has not been able to have an AA and non-AA situation in the same camera even at the mega bucks one pays for a Leica, so maybe it can not be done.
If this information is incorrect, please set me straight. thanks

...then the "E" brings these back into the same Pixel, while the non "E" with the AA filter...In a magazine from the UK (Advanced photographer, April page 83) it is claimed knowing that in the case of the E, the AA filter is not removed but rather its effect 'cancelled' via a clever trick. This is how Nikon achieves economy of scale by having only one assembly line and very little disturbance from the regular flow. They did not disclose the 'trick' and did not mention anything that could indicate weather the effect could be turned on/off by the flip of a switch.

@Teo,
Yes, I'm sure if they were to attempt to design a user selectable filter, it would be vastly different from what they are doing currently.
But, IMHO, designs should be well thought out in advance before beginning any implementation.
Perhaps Nikon thought they would sell more cameras doing it this way.As a side note, I came across this site which is selling AAFs that screw on like any other external filter... If this actually works well, it might be invaluable to the 800E.

Why has the link been removed ?
That's just lame !Thanks for sharing with us Paul :)
Most likely the link is removed because commercial links are considered not a part of NRF. Otherwise we would be totally overwhelmed with links attempting to sell something. It simply makes sense to keep all commercial interests other than sponsors (the ones who pay for keeping the forum afloat) off the forum. Please believe me, I found this out early on.
But as to the topic.... the optical AA filter takes one pixel size focal point and splits it into four points. The the "secret" occurs in the NIKON and in part the image is returned to a single point, but a small amount of information is allowed to the other pixel areas... that is actually creating a "blur" at the pixel level. In the D800E, the second layer of the AA filter simply puts the four points back into one, thus canceling the initial effect and having the final image seen by the sensor as that without any filter. A lot of fancy mathematical/physical theories cover this, but it has something to do with what the software does if it sees a repeating pattern across the pixels and how this creates the moire pattern seen in the final product. The "blur" apparently allows the soft ware to distinguish between a regular pattern more easily at the level of sizes close to that of the individual pixels. Er, sort of...
At some point, this AA filter effect may be possible to achieve somewhat like Sony does with their semi transparent camera mirror system they use in place of a moving mirror. And the AA filter could be turned on and off electrically. But, this may be a very expensive technology, so much so as to place it outside the current markets demand. Less expensive to own two bodies, D800 and D800E.
I think the optical filters which go on the lens are actually for another purpose. Obviously, if the solution was as easy as an external filter, the Leica would offer a filter to provide this.
Just my thoughts

Just returned from picking up my in-store ordered Nikon D800 from a local Best Buy. Last Wednesday, after reading the NR blog, I went to the customer service counter at a Los Angeles-area Best Buy, and performed an "OMS" order, paid, and the camera was delivered to the store from the warehouse in two days. Got lucky with the battery ('C' series), but the camera does appear to have the left-focus sensor issue. Left focus points continually focus further than the desired focus distance (I used small, shiny metal screwdrivers, with fine printing on them, using the specular highlights on the horizontal metal shafts as focus targets). Center and right focus points acquire dead-on. What to do? Keep it and take it to a Nikon repair center, or return it?

I just read the earlier link to Ming Thein's report of the D800 left-focus point problem. It seems, I'm discovering the identical problem, since I first tested the focus-point issue with an AF-S Nikkor 24mm f/1.4G also--the same lens Ming reports as having a problem. Oddly, it's a problem specific to this lens (or, at least, most-pronounced--I haven't checked any of my other lenses yet). According to Ming, it's a problem confirmed by Nikon, with no apparent fix yet.

How do I check if my left focus point is not working?
Newbie here, don't be afraid to over explain!

Went to pick up my D800 at a local dealer yesterday. We threw a lens on it so I could do a couple of test shots and autofocus continually hunted and never stopped. We put another Nikon lens on it and it did the same. In Live View it focused. I haven't heard of this one yet. They said they have another D800 coming next week but now I am extremely leary of the quality of these cameras at this time. Has anyone else seen this eternal autofocus?

I have not noticed any focus issue yet. I have only used my 28-300 with it so far though. Took 353 shots at the Zoo and no focus issues due to camera/lens. Had a few issues with plexiglass and chain-link fences though. :-)
Camera picked up at best Buy end of March. No dirt/oil/grease issues on sensor, no focus issues. I has been great. Awesome battery life even with the BlueSLR on.

JeffOff topic. Jeff, BlueSLR is compatible with D800? Where do u plug it in? It has no USB 2.0
Also what featured work with it besides gps? Remote shutter?
Thanks.Posted 1 year ago # -
@Pablo
I have only used the GPS location function so far with the D800. I got the iPhone unit form BlueSLR directly. It plugs into the 10-Pin connector. You then pair it with the iPhone. Very simple. I will try it tomorrow and report what works/doesn't.

I got my D800E in the mail yesterday. It was with much trepidation that I tried it out, hoping for no crazy problems, as I have no camera store for 100's of miles so returning it and getting another would be quite a bit of work.
Anyway, a couple observations - I have NO dirty sensor problem after almost 1000 shots so far. I have no problem with AF points on the left side with my 17-35mm wide angle. I don't have any AF hunting issues after I configured it correctly - which took me a while to figure out. Regarding the "green-tinted" LCD issue, I noticed that outdoors there is NO problem. Indoors, using flash but under fluorescent lighting, a green-tint was evident. After testing and looking at the jpegs (I have no RAW converter as of right now that works with D800 files) I would say that the Auto white-balance errs slightly on the side of green. I changed it to a click or two towards magenta and it was fine.
Overall it seems I might have lucked out and really don't have any problems, save for slightly green automatic WB.

Today I noticed that the RAW files of the D800 are not readable when taken under the following conditions:
- LiveView mode
- LiveView selector is set to "movie"
- Image taken by using the normal shutter button.I use Lightroom 4, so the problem could also be located in this piece of software.
When shooting JPGs the files are readable under the conditions mentioned above.

If you don't mind my asking, what serial number did you get? THanks.

Maybe this will not help, but I updated to Lightroom 4 from 3. If I tried to download RAW from my D4 to the LR3 catalog... no deal. But the new LR4 catalog seems to work just fine. I am shooting 14 bit lossless compressed and get about a 20MB file to LR4 this way. Maybe the file size of 36MP into 14 bit lossless compressed is so large (45MB) that some other adjustment of LR4 is required. Good luck.
