Hi I just bought a D70 a few days ago and got a chance to mess around with it today. I noticed that all my pictures have a little gray dot/blob in the exact same place in all of my pictures. They vary in intensity but are in the exact same place. Here are a couple pictures:

Picture 1
Picture 2

Any idea what this could be? I don't know if its the lens or not...don't have another one to test.

Thanks for any help,

Denny

/edit
I was looking at the sensor and there was indeed a dust particle that I could see....I used a blower and some of the liquid came out and now there are small spots on the sensor. I know you're not supposed to wipe it or anything but can it be fixed at a repair shop?

Could be dust on the sensor

It certainly does look like dust on the sensor. Did you use a small aperture setting, e.g. f/16 or f/22? The small the aperture, the more likely that dust will show. If that is a piece of dust, it's a darn big one.

Brand New and big ol glob of dust on the sensor. Easy enough fix. Get one of those bulb blowers, turn on the camera and go to the menu with the mirror lockup, take the lens off, say yes to lockup the mirror, and use the blower on the sensor. I hold the camera above me so that the opening is down so it hopefully falls out. DO NOT TOUCH the sensor, just use the buld blower on it. Turn off the camera. Replace the lens and go outside and take a shot at the sky with the aperture very small. Check it out to see if it is gone.

Thanks for the info...will try to blow the dust out. I hope it's just dust!

Looks to me like dust on the lens, not sensor. Although it's hard to see from the pictures, but it looks like the blob is blurred differently, which would be the case if you use different lens settings. If it were dust on the sensor, it would have been sharper and of precisely the same appearance between the shots regardless of the lens settings... I could be wrong though, it's hard to see from those pictures.

But wherever the piece of dust is, it's easy to clean, as all the folks above said.

Make sure that you have plenty of battery power or a power supply when doing this. Power failure is very bad.

Liquid came out of a bulb blower? I have used a buld syringe (for sucking snot out of babys noses) before, but made sure that it was not a USED one. (C: You used canned air huh? Not suppose to do that.
You do have a predicament now. A repair shop would be best to clean that now. I would order the stuff to do it myself, but I am kind of a tear it apart and fix it myself type person. But that is me.

AAAAAwwwwwwwwwwww cute. Your first wittle dust bunny.

If the liquid came from a can of air/CO2, or other canned "blower". Take it to the repair shop. If it came from a bulb blower (... from baby's nose, etc), you can probably clean it yourself using "Sensor Swabs" and the cleaning liquid they sell. You can purchase this via web or in person at most Calumet Photo stores.

For a good proceedure on cleaning sensors and more information on the technique involved, check out Thom's website at: //www.bythom.com/cleaning.htm . I use a similar technique and have had not issues.

Two thoughts...
1. If you don't feel comfortable or confident with the technique, let the repair shop do the "dirty" work for you.
2. Allways do this with ONLY A FULL CHARGE OR A/C POWER.

Good luck!

My advice is don't take chances doing it yourself. The cost of a professional cleaning will be more than worth it compared to you scratching and ruining a brand-new sensor.

I would take it back from where ever you got it and get another camera. If its brand new, then they should swap it out no questions asked.

There is a good idea. Act dumb, and say this crap keeps showing up on the pictures. This is how I got my D70 kit for $300 off normal price (when you couldn't find them anywhere) as an open box, but I had to send it in for a mirror lockup repair (FREE). Just tell me where you are taking it back to, so I can get a backup! (C:

I just took a picture of my wall at f/22 and autoleveled it...i made it a lot worse using that compressed air can :-\ I shouldn't have done it. The ring-like ones in the top left is the fluid that came out of the can. I ordered a SensorSwipe, Eclipse, and PecPads last night though. I hope I can get most of it out.

DAMN!! That sux! The Sensorwipe and Eclipse does wonders though to clean. Just read and reread the instructions and take your time. GOOD LUCK!

The canned air stuff sucks! I recommend paying $10 for a Giottos blower. It looks like a bomb. It pushes out some serious air with each sqeeze. It has kept my sensor nice and clean with a couple of blasts whenever I change lenses.

I had the same issues with my D70, i just brought it back and exchanged it straight up. the problem you may run into is if you filled out the warranty cards, specefically the one you would send in with the camera for repair. if you didnt fill this in they you should be set, if you did, you can try and talk to the store you got it at to make an exception though they dont like to make that normal practice. However, if you look angry enough it will work. also helps if you are dealing with an understanding employee.
