My NEX-6 sensor is dirty?

My NEX-6 sensor is dirty?

I see that spot in the viewfinder even after replacing the lens.

The stain comes out in the pictures.

Can I see sensor dirt through the viewfinder?

Beautiful picture by the way.

Larger "dust" like that is what i think of as a fiber floats around pretty easily.  You need to get yourself  a hand operated rocket blaster - air bulb type of device so you can blow it away without risking any damage to your sensor.  buy one of these blowers designed and cleaned for camera use.  (I've read of people using something designed to blow up air mattresses and toys, - and succeeded in getting talcum powder scattered throughout the inside of their camera - not a good thing to do)

Also, point the lens opening downward when blowing into the camera.  Do not extend the blower nozzle into the interior of your camera body.

I had a fiber like that about a month ago, blowing seemed to move it from one area to another until it finally left the camera.

Thanks, Philnw2

I never cleaned any sensor, I see that I'll have to take the plunge

No problem, just clean it. Here's how

The sensor has a coating on it that makes it pretty safe to clean it if you exercise reasonable care.

First thing is to try a blower, as another poster has suggested.  Do not use a canned pressure blower as it mulitiiple risks.  The "Rocket blower" is very popular and is what I use.  Hold the nozzle and the bulb, so that the nozzle does not impact the sensor.  If the substance is not sticky, dust for example, it will blow off.

If the blower doesn't work there is a product called "lenspen" that is very good for more stubborn dirt. It comes with a brush and a carbon wand absorber.  First you brush, then you use the carbon wand.  This works very well.

You really should NOT use the lenspen brush end on your sensor. But its OK to use the flat wand tip.

There are various "lenspen" models, one is 'sensorklear' specifically for the sensor, but the regular lenspen (for lenses) has the same wand tip - so its ok to use for sensor.

To clean sensor:

a) first use rocket blower only - it may be enough to blow out the dust & you never need to touch the sensor at all.

b) If that doesnt not work, use a dry cleaning method such as lens pen.

c) if that does not work, use a wet cleaning method such as Sterile wipe or special cleaning kit.

LensPen method

1) On your NEX menu settings put the camera into cleaning mode. Turn off camera as prompted.

2) Remove lens & hold the camera so that the sensor is vertical or facing down (its better to avoid having the sensor facing up so more dust can get in)

3) Use the wand tip to clean the sensor, don't press hard, but just some light pressure to clean it is ok. Dont use the brush end because it can transfer particles from around the sensor & its not a soft brush, its a bit 'scratchy'.

4) Use a rocket blower (hand held squeezy bulb type) to blow out any remaining dust or carbon - again, hold the camera with the sensor facing down so any dust can fall out.

5) Replace lens. You're done.

Check the results by taking a photo at f22 of white computer screen (make a blank text doc). Slow shutter is fine, wiggle the camera a little when you take the shot as this will ensure any spots you see are sensor spots & not spots on your computer screen. You can adjust the levels/contrast of the image to help show up any remaining dust. Some minor faint spots can be left alone as acceptable, you will never see them in real photos.

If you need to resort to wet cleaning then you are best to get a special kit. But you can do a DIY method: http://www.cleaningdigitalcameras.com/howto.html

What's your source for this claim?  I don't think there is any problem with the brush, unless there is some information I'm not aware of.

LensPen/DigiKlear™ - This technique has been seen being used by Canon Techs, although it isn't their official policy. Due to the fact that the LensPen can't be cleaned, it should be disposed of and replaced on a regular basis.

  1. Clean the Low Pass Filter with a foot or hand blower.
  2. Wrap a dry kimwipe or Pec*Pad™ in a pair of tweezers making sure the wrapped product sticks out much farther than the tweezers tip.
  3. Wipe the Low Pass Filter clean with the wrapped tweezers. This is more of a brushing than a rubbing exercise, do not put any force from the tweezers onto the Low Pass Filter.
  4. Polish off the Low Pass Filter with the pad end of the LensPen NOT the brush end.

The sensor dust is much less likely to show if you don't use really small apertures like f/13.  That should should be fine at f/8 or even wider.  As a general rule, I avoid shooting at anything smaller than f/8 on my NEX.  Dust may be large enough to still show at f/8, but it won't be as offensive as at f/13.

I use a rocket blower and if that fails i use a q-tip to wipe the sensor....

Photography for me is not about recreating what i saw through
the viewfinder but to show people the way i want to see the world

I had dust all over my sensor.  Would not blow off, so did a wet clean.  Worked well.  The sensors in these cameras get dirty quickly so investing in cleaning kits and blowers is a must!

Re: My NEX-6 sensor is dirty?

I used a rocket blower and the dirt gone.

Thanks God, no Lenspen, at least now

Thanks, everybody, much appreciated

Re: My NEX-6 sensor is dirty?

I use and recommend eclipse solution and a pec pad with a spatula like tool. I have been using this method for more than a decade.

All sensors get dirty over time.
