Need to clean mirror or lens

I have a large dust particle or some kind of hair that is visible on all my pictures. I have tried to clean the inside and outside of the lens (I have the kit zoom lens) and even gently wiped the mirror with a photo cloth to no avail. What should I do to clean off all surfaces that may be affecting my picture quality? Is there any professional cleaning service that I can rely on to make sure I get high quality pictures? Thanks in advance!

Re: Need to clean mirror or lens

Your camera has a sensor clean option. use it. never trust your fingers to hold your shutter open because you could accidently close on whatever your using to clean it and damage the shutter. go to your menu and select sensor clean and the shutter will stay open as long as you need. the camera will instruct you how to close it.

Re: Need to clean mirror or lens

The particel or hair is probably on the IR filter glass that sits over the sensor. You could try puting the shutter on bulb. If you then remove the lens and hold the shutter release you will be able to see the filter glass and possibly be able to remove the particle with a blst of compressed air. Do this in a cleanish room or you will make things worse.

A small brown spot is on all of the pictures I've taken starting today. Looked back at pictures from last week and didn't see it. Same place all pictures, both lens.

Hiit is simple dust particles. I can let you know by very simple tip. But unfortunately I can not describe in word everything. First thing you can try is that you can you ear know remover or squeeze blower. Set the camera at ccd cleaning mode.(not auto mode) See front inside of mirror box when mirror goes up, you can recognize the brown spot. Blow with the blower. Other method is I can not expain everything.

I've got some visible(I see it on the pictures and on the digital display) dust (tiny hairs etc) on my lens (actually inside) so it seems I can't get rid of it without taking my cam apart. The dust is then...

If this is a fixed lens camera (you didn't give a model) I'd suggest strongly for you not to attempt to take it apart. Hopefully what you are experiencing is dirt on the outside of the lens. If so turn on the camera huff (breath) on the lens to create a slight amount of moisture and then use a lens cleaning tissue to gently clean the lens.

If as you say this dirt is on the inside then I would suggest getting it cleaned by a camera repair facility. Problem there is a lot of these point and shoot cameras cost more to clean and fix then it does to just go get another one.

Next thing if the inside is dirty they you must have a lot of lint in your pockets or you have been using this camera in a dusty environment. For carrying it would be best in an actual camera case rather then an open pocket and for dusty condition I've used shallow water camera bags and I've also used ZipLock bags while photographing a waterfall.

My panasonic Lumix DMC-ZX1 shows 3 dark spots and 2 hairs on all pictures. When I zoom-in the dirt is more visible and when I zoom-uit I dont see the hairs any more and the dark spots appear wider and...

Yes, you can clean. Not as complex as I originally thought.
1) Remove all of the silver screws
2) Separate the silver case (should split in 2)
3) Remove the 3 black screws in the middle
4) remove the center square cover that is over the lens
5) Use a duster spray to clean the lense and mirror
6) Reassemble in reverse order
Not knowing what I was going to get in, the entire process only took about 7-10 minutes.

Email me at with any questions.

How do I clean dust inside the camera? I noticed some splotches on my photos, then looked closely at the lens and it appears there is dust on the inside of the lens.

You can't clean inside the camera. Dust inside the lens would be so out of focus, it wouldn't register on your pics unless the particle was huge. Do these splotches only happen in your flash pictures?

Dust behind lens

If the dust is inside the lens, then you are unlucky. Canon lenses (except for a select number of the L series lenses) are not dust or weather sealed. So each time you work the zoom mechanism on a inexpensive EF 75-300mm f/4-5.6 III lens, the mechanism is working like a giant billows allowing air (and dust and moisture) to flow through the lens and camera body. Sometimes large dust particles can accumulate on the different lens elements, but it does not have any impact on the quality of the photo

If the dust is creating problem fro your picture get it fixed from service center i will suggest you should not try to open it

Hair and particles on pictures-not on lens or mirror-on sensor

You must have dusty mirror box area. Here is what you should do. 1. Remove lens from the body. 2. Blow out any dust from the mirror box area using can duster (careful not to spew out liquid). 3. go to menu and select mirror up or ccd clean mode. You can also set at manual shutter speed "B" and hold up the mirror. 4. Blow out dusts over the CCD sensor (Do Not Use can air! If any liquid sprayed on CCD the cleaning gets worse) so use Hand-squeezee air bulb. You can purchase one from any camera stores.) 5. test shots and repeat. 6. If this procedure did not resolve the removal of the dust, you can purchase a cleaning solution package and try it. I do not recommend it becasue our techs get lots of cleaning requests from these package. Remember, if you are using these solution, 1. Never give any pressure to the screen, just tissuie touch pressure only. 2. move circular motion as you mouth blow the air as you move. complete the motion exiting through the corner of the screen. Did not work? send it to repair techinician! Our tech cleans it for $49. 24 hour turn around and also checks the camera too. Good Luck

Water spot inside the lens on my Lumix camera


To take the lens off, the camera has to be dismantled, and unless you are an experienced technician, there is a 95% chance that the camera will have more problems than what it started with.

Have you taken any pictures with the water spot inside the lens? If it is visible in pictures, then you have several options:

1. Ignore it.

2. Leave it there and use an image editor to clone out the spot in the picture. (Recommended).

3. Take the camera to a repair shop, or mail it to Panasonic's service center. This is the expensive option, to remove the water spot, the price most likely will be well over $100.

4. Buy another camera. The FZ7 is rated to about 50,000 shots, so if you are approaching this number they it may well be worth it to just get another camera.

Unless the spot is seriously affecting your pictures, then leave it there. By having the camera opened there is a high chance that other problems will be introduced, such as: fingerprints,dust or hairs inside the lens or misaligned lens elements.

My FZ7's lens is full of dust, yet this is not usually visible in pictures, when it is, I can usually remove it on the computer.

I would recommend taking the camera to a service center as a last resort.

Dust inside my d200

The view finder and focusing screen are separate from the CCD sensor. The mirror reflects the image to the view finder until you take a picture. Then the mirror goes up, the shutter opens to expose the CCD to capture the image.

If you have a lot of dust, you should look into a cleaning kit, or have it professionally cleaned. This will show up on your images as white and/or black specks.

Dust Behind Lens on F707

That's odd. I had the 707 (may she rest in God's eternal peace), and never thought that dust could get behind the lens. Do you see the dust when you look through the EVF, or when you look at the lens itself? Either way, one way to test it is to set the camera to the smallest aperture (f/8), infinity focus, and shoot a clear blue sky. Open the picture in your editor program, and see if the dust shows up. That's a technique to use with an SLR to see if the dust inside would affect a picture, so I'm not sure if this will work with the 707.
