Does dust specks inside lens cause blur in the pictures?
Hi; I'm getting a little whitish blur in my pictures. Same place every time. When I look at the lens (plastic cover, looking inside at aperture of lens) I see a couple largish specks of dust adhering to the inside of the lens. Is this the problem? Anyway I can 'blow it out' using canned air? Or can a local camera repair place (Canon dealer) take care of this? (If that's what's causing the blur in your opinion). thanks, John

If you have a SLR camera you can take your lense off and clean it.. I do not reccoment canned air because if you do not use it the right way liquid will come out. At best buy they have cleaning kits, and in their kit they have a little brush that you can squeeze regular air and brush off anything on the lense or around the lense, If you have a SLR camera you might have a built in cleaning option... SLR means Single Lense Reflex and this means your lense can come off/interchangable..

Question is, Is your lens blurred,or are all your pictures blurred? If you can see the front of the lens is really dirty, you could try to clean it with a lens pen. One side has a soft brush to remove the dust and perhaps other debris. Please try to remove debris with a little presuerd air. If only smear is left on the lens, you than can use the other end of a lens pen. It has a very soct pad, with wich you than can remeove smear. If the lens looks ok, please don't touch it. Perhaps you don't take enough time to let the camera focus on the subject. When making a picture, press the shutter release button half, till he AE/AF indicater flashes and you hear a beep, then you can press down and make the picture. If you are making pictures without a steady hand, pictures also can come out blurred. Special when there is little light avalible. Then choise a higher ISO. I hope this helps. You still can fine the manual online.
dont worry about dust too much unless it actually affects your image sensor.check it by pointing to a white wall or sky with f put to it maximum like 32/22 , focus and take pictures.. if its problem with the lens then it will make prominent dark speckles on the image.. but if you get dark speckles even at lower f - stops like 1.4/3.5/5.6 then its dust in the sensor.
dont try cleaning your sensor yourself as you may spoil it and finally have to refer a service center of the brand .
the lens does not come off of that camcorder easily. if the dust is on the outside just use a little windex (spray the cloth, not the lense) and wife in a circular motion. If the dust spot (maybe its not dust). is on the inside you will have to have the lens taken off by a professional.
The spots can be in the inside of the lens settings to the CCD/imager.
If the cleaning of the lens is done well it can be a speck of dust logged in to the screen and having it on the image.
A careful cleaning in a dust proof set up is required.
I'm having a similar problem with my G2. It happened after I took somephotos when it was snowing. I think some moisture may have got on thesensor and left stuff on it. I don't think it is the lens that iscausing it, as this can never leave this kind of smudge. I stillhaven't got round to doing anything about it.. I would be interested tohear how you got on with getting it repaired.
I found this article which confirms what you were saying about thehigher f-stops (and also provides and explanation). I have also checkedthe EXIF data on my photos and found that there is a correlation withhigher f-stops and degree of blur (with very little to no blur at thelower f-stop values).
Don't. Unless there are some really big specks of dirt inside the lens then they will have no effect at all on picture taking. To prevent the problem getting worse always store your lens with it's front and rear caps on and inside a lens bag. Also make sure that your camera bag is clean and isn't shedding fibres from the inner linings.
Dismantling your lens to clean it is really a job best left to a professional who will then additionally check and clean/lubricate the moving parts inside the lens.
It is probably a speck of dust on the sensor. Get a blower from any camera shop, remove the lens,lock up the mirror (mirror lock up in camera menu) and give the sensor a good blow ( without touching it) while holding the camera front down so that any specks of dust fall away from the sensor. Sometimes specks can stick (pollen for example) in which case you could try a disposable swab and cleaning solution, although if unsure most camera shops provide the service pretty cheap - the sensor would be a lot more expensive to replace if you mess it up.
appears to be dust inside lens - small white specks
