Hello,
I just received my D800 here in New Zealand and after 5 or so pics two black spots showed up in the sensor (tried different lenses and it is still there).
Tried some air blowing but it is still stuck there. I haven't changed lenses by the time they appeared. Weird thing!!!
One is round, very dark in the middle and fades away. The other one is not so round.
There is a link here so you can see what it is.
The question. I am not expert in sensors, so do you think I can have some dead pixels already or its just a matter of sensor cleaning.
I just sent an email to the store and the authorised service centre (easter today).

Picture not found!!!

If they are one or two pixels large (i.e. really small), then it might be dead pixels otherwise, you may have something like dust in there. Is it semi-transparent or solid?

We have had cases of oil on sensors as a left over of the manufacturing process on other cameras, and don't use a spray can of air on the sensor, as you'll be spraying chemicals on it. the propellent can leave a fine layer on whatever you are aiming it at...

Hi paccini, what a shame to have any issues with your brand new camera :-( Have you actually locked the mirror up and looked at the sensor? I don't know if you have one, but a sensor loupe would answer the question of if it's dirty.

From your description i would not say "dead Pixels", but just dust ( or , like some have xperienced oil ? ) .

If your "dust" happens to be "pollen" then it's a bit stickey , but will let remove itself with an arctic butterfly or similar easely...

You can try different apertures, and see what happens. Just shoot a white wall or clear blue sky with apertures varying from wide ( f2.8 ? ) open to almost closed ( f22 ? ) since dust looks different at different apertures, dead pixels always look the same at all apertures...

OK guys, thanks for the feedbacks. I really appreciated it.

@bjrichus: they are more than 2 pixels large. Thanks for the advise. I havent used spray can. Just the rubber blower.

@SkintBrit: yes, I had a look with mirror up and I can see two very little spots over the sensor (naked eye).

@DutchNikon: man, you are right. At wider appertures I can't see the spots. Smaller, yes!

Reading what you told me, guys, I suspect that it is left over oil from the manufacturing process.
The weird thing is that its appeared after the 5th or 6 th shot, when I started using HDR mode. Before that, it was normal.

Do you think I am covered by Nikon warranty?

Same here
I think it's dust...
It's a good 20-30 pxs around the center of the image...

Whats the best way to remove it ?
What if it's oil ?

I will probably bring it to a big photo store and ask them tomorrow

I looked with the mirror up and I can see a tiny (I think dust) bright speck
I did't change lens much

Thanks for your advises

Cheers

@paccini - please make the images available for all to see or I'll delete this thread - You have to change the security settings on picassa

Definitely, if you send it in (and tell them how many shots you've taken) they will clean it for you F.O.C. I'm sure they'll sort your shipping costs in this case also. I don't know the law in New Zealand, but in the UK I would just return the camera and ask for a replacement, (I appreciate that in the case of the D800 that is easier said than done)!

>>Just the rubber blower.Just the rubber blower.<<

Mmm What blower do you use ?
Hopefully its not one of those rubber ball blowers with a brush attached ? Those realy spell trouble for sensor cleaning...

Also when using a blower, keep the camera with the mount poined downward and use the blower under an angle ( otherwise it just blows the dust on the sensor/filter instead of off...

A good blower has a dust filter at the intake end like my favourit one : "Visible Dust Zeeion " ( not cheap... :-) )

Sorry guys for the link. I think this one works (downsized to about 4096 px):

https://picasaweb.google.com/lh/photo/ri8guWmZoREHn3p4WVKbVNMTjNZETYmyPJy0liipFm0?feat=directlink

Frankly, lets see if they replace this one. I think nobody would want a camera with 35 or so pics with its sensor already cleaned, hey!

I could see 2 tiny bright specks and around 30 px round as Teo said. It started after the first HDR pic.

Thanks for all answers again!

Cheers!

Teo said:...What if it's oil ?...

The first batch of D7000 had splashing oil problem from the mirror box. If the dots appeared after a few shot and in different bodies, it could be the same.

I was told from the technician at my local shop that oil on the sensor will eventually damage it and has to be removed. On my friend D7000, he cleaned the sensor, then realized more oil was splashing, sent it to Nikon for repair (took 3 weeks) and paid back the sensor cleaning cost, 3 months passed the warranty end.

Looks like dust.

Is this your first DSLR?

Mine looks similar to the one on the pict of paccini
But it doesn't really look like oil when looking at the censor directly
I'll try a good blower tomorrow and tell you how that goes

Thanks

My D800 has a single hot/dead pixel. Is there a solution?

If it's in the middle they will most serenely replace it
but if it's on the edges, then I'm not sure
I remember my old iPhone had like 9 dead pixels and I needed 10 to get a new replacement unit LOL

But please, do contact your local shop for advise

If you contact Nikon, they will happely "remap" your sensor..

There are next to always "dead" pixels on a sensor, but motly they are "mapped" out of the picture (switched off...) without anybody noticing...

Tell your camera to clean the sensor twice in a row. I apparently reset/remaps the sensor. Works great!

Again, guys, thanks for the reply. I just have to wait until tomorrow (Tuesday) to have an answer from them, because its holiday here now.

I tried blowing as NikonDutch said, mouth pointed down and blowing in angle. No brush on it. Tried as well double cleaning as Newfie, but nothing changes.

@NSXType-R: no, this is my third one. I have a D700 too and had previously a 5D MK II. I am far from being good photographer. As I work with 3D, I mainly use it for textures cuz we need huge images to get good renders out of the computer. Yes, I am newbee :)

Thank you and I will post here what Nikon NZ tells me if you are interested.

Cheers

That looks like, dust/dirt/debris to me. It's not always easy to get off. I've had dust that was particularly "sticky" get in my D300 and do the exact same thing.

I see. How did you deal with dust with your previous cameras? I still think it's dust.

As a very last resort I would say try a wet clean.

But if I were going that route, I'd sent it in for cleaning at a shop or back to Nikon for cleaning.

On my trip to the Caribbean, when I exit and enter the ship I always encountered a big change in humidity. I never knew about it, but I think the condensation sort of "welded" dust onto the sensor. I still have some really really stuck on pieces of dust on my sensor. For the most part it doesn't bother me because I don't shoot professionally.
I don't trust myself around sensors.

Hey,

i got my D800 in March and up to now i'm very happy with it. I'm working on a Video Project right now and i shot several takes with the d800.

When i was checking my takes i noticed some failure in the footage. I uploaded a picture where you can see what i mean. It appears for about 1 second and then it disappeares:

http://www.imagebanana.com/view/rh5sxt0o/20120408_Bildstoerung_720p50fps.jpg
http://www.imagebanana.com/view/9jo1q3eo/20120408_Bildstoerung2_720p50fps.jpg

I didnt check all the footage and till now only one take is affected by this failure.
What do you think? Is this normal?

I was shooting with a d7000 half a year and i never saw such a failure on any footage.

Hope you can help me. Thx!
