Permettimi di dissentire su tutta la linea. La Nikon ha fatto orecchie da mercante con la D800 e pure con la D600. Qui tu stai facendo disinformazione : "ribollire di pixel" ?! Ma che ne puoi sapere di quali siano le cause di questo problema di pixel bianchi ? E' un fastidioso problema, ma solo per condizioni di scatto "particolari", o forse hai delle informazioni a noi non note che ti inducono a dire che dopo n scatti il sensore della D810 si brucerà del tutto ?
La Nikon ha semplicemente capito che se faceva orecchie da mercante un'altra volta, poteva mettere una pietra sopra ai suoi profitti per i prossimi due anni.
ho letto questo documento ufficiale. un po' più dettagliato del comunicato italiano. il problema del ribollir dei tini, non è legato semplicemente alle lunghe esposizioni.
The official version in Japanese was a bit lengthier and contains more information:
To users of the Nikon D810 digital SLR camera
Thank you for buying Nikon products.
We have received complaints from our customers regarding an issue where bright spots might appear in images at long exposures, or when images are captured in 1.2x crop mode using the D810 digital single-lens reflex camera.
We have confirmed the issue with bright spots appearing in images captured in 1.2x crop mode and when photographing long exposures. Customers who already purchased the camera will be supported by our service organization. We apologize for the inconvenience this issue might have caused you.
How to check if your camera is affected
In order to check whether your camera is affected, please click the below “Serial Number Check” link, where you will be able to enter the serial number of your D810 camera. Based on the serial number entered, we will provide instructions on how to send your camera to a service center. If the page shows that your camera as not affected, it does not need to be serviced and you can use it with confidence.
Serial Number Check
It should be noted that even if the serial number entered is confirmed as needing repair, if the black circle identification mark in the tripod screw hole of the bottom of the camera body is already there as shown in the sample image, it means that the product has already been inspected and adjusted for this phenomenon, so you can use it with peace of mind.
Black circle: inspection and adjustment identification mark
[For Correspondence]
If you have a D810 digital SLR camera that is affected, please consult with our service organization. We will implement a firmware upgrade and perform adjustments on the imaging device in order to improve this phenomenon. With this repair, the occurrence of bright spots is reduced when images are captured at 1.2x crop mode or when long exposures are used.
When you need to improve sharpness and resolution of the captured image, even after the above-mentioned repair, bright spots might appear when shooting at slower shutter speeds than 30 seconds. If you set “Long exposure noise reduction” value to “Yes”, you can further reduce this phenomenon. Thank you for your understanding. To offer products that will satisfy our customers in the future, we will continue to perform further research at our company.
[How to apply for service]
Instructions on how to apply for service will change by country
[Delivery time]
Once your camera is received in the service center, we will perform the repair within one week. There might be further delays due to large volume of customers, so we are asking for your patience.
We deeply apologize for this inconvenience to our loyal customers.
In regards to our company, we are willing to do what it takes to achieve perfection and to improve the quality of our products in the future, so we ask for your continuous support of Nikon products.
