Nikon service could reduce but not repair my left D800 AF issue (end of October 2012)

I am pretty sure the Nikon Service Switzerland did its best to fix the left AF issue of my Nikon D800, no jokes. The problem is: they could not fully repair it.

I gave in my 3 week-old D800 camera with a 0 AF fine tuning, perfect central and right AF points, highly blurred (unusable) left AF side.

After 3 weeks
I got back a camera with a -12 AF fine tuning, a slightly blurred right AF and a slightly better left AF. My test (click on the first picture table for full view) was carried out with these specs:

– camera on tripod

– Mup to avoid mirror vibrations

– liveview focusing vs AF points

– several pictures shot for each points

– around 3 meters far from the target

– 50 mm f/1.4 G mounted

I compared for AF accuracy and sharpness my 2,700 CHF Nikon D800 against the entry level Canon 60D (800 CHF value). The Nikon D800 could never produce with left and right AF points any sharp picture, while the Canon 60D was sharp at each trial (click on the second picture table for full view)

So, what’s next? Should I wait for Nikon to find a solution to the problem? 36 Mpixel of out of focus images for a sensor that got the highest DxO rating, this is what I would call a waste of technology.

    oh no!!!! but did it really matter for your actual photo shooting?

    Well, it is nice zooming into a 36 Mpixel picture, crop it and still see focused details – I cannot do it with such AF system. So, I have 36 Mpixel I cannot use and 51 AF points of which I can trust only the central part … a camera equal to 10 AF points / 12 MPixel for 2,700 CHF? I feel somehow stupid I bought it. Additionally, I am not ironic when I write what a waste of technology: it is no doubt the sensor in the D800 is great, pity in front of it there is such a cheap AF system.

    Ciao Lorenzo, del problema dell’autofocus si parla in molti siti, fra cui, se non l’avessi già visto, questo

    dove si dice che per eliminare il difetto occorre intervenire sul firmware della camera e procedere al riallineamento meccanico del modulo con operazioni che possono essere eseguite da un centro altamente specializzato (viene indicato Dusseldorf).

      Il Nikon Service svizzero mi aveva assicurato che la Nikon ha distribuito i protocolli per la riparazione anche a loro. Potrei spendere 400 CHF per spedire la macchina al Nikon Service di Düsseldorf in un pacco assicurato, il fatto e’ che non ho la sicurezza che possano fare qualcosa di meglio dei colleghi svizzeri. In internet, le uniche persone che hanno avuto in Europa la macchina riparata sono quelle a cui pezzi della macchina sono stati sostituiti.

    Dato che il difetto si è manifestato durante i primi 30 giorni perchè non la restituisci e ti fai rimborsare?
    Aspetti qualche mese e quando avranno risolto il problema (se mai lo faranno) te ne comperi un’altra!
