    Defects in D800

    As indicated before, Mongo has waited 8 years to upgrade his camera body waiting for the quantum leap instead of the yearly incremental steps from his D200. So he bought a D800 about a month or so ago and about $3500 later. In many respects the camera disappoints but some are to scared to say so. More and more Mongo sees others on the net pointing out faults. They ring a familiar bell with Mongo.

    Speaking to Sar recently, we both seem to have had at least one similar negative experience i.e. the focus seems to just "lock" at times and not refocus when you aim at something else or "freezes" on the object you last focused on and not refocus. Luckily, these were temporary "freezes" which thawed out moments later but annoying nonetheless and what Mongo considers is a design or factory fault !! Many others have reported the same experience on the net. Too many to be a coincidence.

    Additionally, Mongo was unhappy with the sharpness/focus he was getting from time to time. There are countless owners who reported the same problem on the net world wide. The specific problem being that the left side AF sensors do not focus accurately. Generally, the middle and right have not been reported as being affected or as badly affected. Mongo did a quick test today to get it out of his head. Unfortunately ,that just put more steam in his head which whistled even more loudly from his ears.

    Mongo's results show what he considers to be very bad AF focus from the left sensor(s) slowly improving across the middle sensor to the right sensor which is better again than the left (by far) and the middle (by a noticeable amount). Whilst the right sensor is the best of all, Mongo is in no way convinced that even it is functioning as accurately as it could or should be - it just happen to be the best of a bad lot.

    3 test images appear below from far left to middle to right sensors. Mongo took several sets and they are all consistent with the set Mongo has attached here. Mongo thinks the difference is quite evident but becomes even more evident when you look at the first and then the last (skipping the middle image). Moreover, the original images show the differences even more dramatically on Mongo's screen at home.

    The images have been standardised in that they have been taken and processed identically. They were taken in Jpeg and no sharpening (except "+1" which had been set in camera) or processing other than reduction for the web has been applied. In any event, Whatever has been done to one image,has been done identically to the others.

    Test details: D800 on FX Jpeg fine, tripod, 70-200VR on aperture priority wide open at f2.8 set to 200mm, VR -off, single spot sensor used for AF, ISO 100, spot metering (but note that all exposures were identical in any event i.e 1/800th, f2.8, +0.7EV), distance to subject about 10 to 12 metres, all images were taken within seconds of each other.

    Mongo used a 70-200 because of its accuracy and sharpness but set at 200mm. Apparently, this problem is far worse and noticeable when trying to use the AF sensors on a wide angle lens , say, wider than a 50mm.

    You wonder how it could ever get through quality control and leave the factory in this state. Mongo has always said that if he wasn't so heavily invested in Nikon gear, he would be buying Canon. Mongo has had enough and it's going back to Nikon tomorrow.

    Roo it is roughly in the area marked in red. Could not be precise as this data was lost in converting the files for the web

    looks like a misalignment of the Af sensor...as you say the far right is the best of the bunch....Ive read posts where this has been fixed is a service..so you should be good after Nikon have realigned the AF array ....a pisser I know. but at least yours is better Than Chris's...his is locking up all the time...in some ways Nikon hit a home run with the D800...but there's a few home goals in there too.

    another reason Im waiting... I've vowed never to be a early adopter again after a Pentax K5 fiasco

    It doesn't seem to matter which brand you purchase the rush to get it out there before the opposition compromises the end product. The bugs which could be easily fixed with proper testing detract from the pleasure and joy of an expensive purchase. You have had the camera for 1 month and found this fault so what were the original testers doing? Quality control? It would appear the dollar is more important and if there are a few complaints we expect a certain percentage so what...... I dealt with a company that supplies faulty products but they would only replace those who complained the loudest. No compensation just replace product. The fact that it could be a 2 hour replacement job didn't seem to matter to them. I lost many clients over that and of course they told all their friends not to use this product. The damage done far out weighs the recall of a product. Good luck with your endevours. cheers Brian

    Disappointing considering how much you invest in these things.

    Mongo

    just for the sake of it I just tried my D700 with a 60mm micro D lens..and guess what..at the outer most AF points..its soft..come in one point either end and the problem goes away...have you tried your D800 one click in from the outer most points ?

    Hmm, interesting analysis Mongo. Im particularly concerned that the focus for the middle isn't spot on, as that tends to be where I hunt most frequency. Will be doing a check of mine as well.

    Yep, the problem is real.
    It was one of the first things I checked with our bodies and both behave the same way.
    The outer left AF point simply isn't.
    The problem manifests itself to a greater degree with apertures wider than F/4.
    I'm sure that a few have been fixed by now around the globe so sending bodies back now is probably about the right time to start.

    I am NOT going to let one small problem mar my experience with a camera that is otherwise excellent and I feel that it is purely going to be a minor focus screen shimming alignment problem ( hopefully ) but at this stage I look at as if it is just another hiccup in photography, not the end of the world.

    As for singling out Nikon as being any better or any worse in respect to "new model problems" than any other maker I still reckon they are ahead by a short nose on the right side of the post to most.

    Thanks for all your replies. Waz, is spot on with what has been happening in his attached links.

    Contacted Nikon and its going back tomorrow for the firmware update to fix the freeze problem and to correct the well known AF problems of which they appear to have done many recently and they know for sure they can correct it.

    as nice as the d800 appears, teething problems are exactly why I have not ditched my d3x in a mad rush for latest and greatest. once problems are established and corrected the 800 will be a formidable camera. dont give up on nikon just yet mongo. the IQ is ahead of a lot of other systems out there.

    Can certainly understand your angst, but on the bright side, it sounds like its a known issue & plans are in place to have it resolved instead of being palmed off as a random event by only a couple of users.
    Hope all gets fixed quickly.

    Modern cameras are extremely complex mechanically and electronically.
    As much testing etc. that goes into them it is impossible to have this tech 100% bug free.
    I guess this is why we buy local (support) and not so much grey esp. camera bodies.
    I'm sure Nikon will sort this issue PDQ.

    forgot to mention that the camera focuses far more accurately on "live view" (which Mongo never uses) because a different set of focusing tools/parameters are used to establish focus. Just interesting to note. Mongo tried it quickly and the focus was far more accurate on live view.

    Mongo is certain they will fix it but it is still a big pain to Mongo and countless other owners over the world so it still reflects badly on Nikon. Other manufacturers may have problems like this also from time to time but they do not charge the sort of money Nikon does - so Nikon have a far bigger responsibility to get it right. It is not good enough to for Nikon or for us to think that because it happens to others its OK to happen to one of the most expensive brands as often or as much. That's just what Mongo thinks.

    Really sorry to read you going through this with your new purchase.

    How long can you own something like this for before you have to send it back to Nikon instead of (if you chose to) take it back to where ever you purchased it from for a full refund as "Not fit for purpose as sold"?

    I got mine grey from SG as some may have read. It doesn't exhibit any of the focus point issues, no lock-ups (I updated the "B" firmware as it was released) and whilst I agree Mongo it would be very frustrating with a new toy, Nikon are no worse than any other manufacturer. In fact Nikon have had a good run of recent bodies behaving well out of the box, and some have been excellent performers. Think D3/s, D700 exceptional cameras.

    A note as well regarding the cost, Canon's new 5DMKIII is more exe than the D800..

    Mine has a production date on the box of 04/12

    What firmware do you have Mongo, and is it the latest downloadable one from Nikon? Your camera may not need to go back, just need the firmware update, which Nikon make available so the user can download and update.

    We have seen these types of 'teething' issues repeatedly. Remember all the Canon 5D's that had their mirrors fall off?

    I too, hold off on buying early batches now, cause of this repeating cycle, not just in camera gear, but all electronics.

    Hi Mongo,

    I was warned by Lance B on this possible AF defect the first day I got my D800.
    In the first week, I did a quick check with my 85/1.4G and couldn't detect any anomaly.
    Last Monday morning when you called me and told me about this left sensor defect, I did about 10 photos using one of the left farest AF points on my D800. All of the focuses were spot on.
    Here is one of them :

    200-400 VRI+TC-20EIII, wide open, 1/125", @800mm, AF-C & Dynamic 51-points, handheld.




    Crop



    I'm sorry that yours has this focus defect. I'm looking forward to hearing the explanation from Nikon Australia on this problem.
    In the meantime, I'm going to do some more tests with my other lenses and with different settings...
