Question about Canon PowerShot G2 Digital Camera

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..

My sony DSC-H5 camera lense is blurred. at first the lens was stuck then i gave a gentle whack after reading one of your solutions. the lens was blurred before it got stuck


It is difficult to say what is wrong, without having the camera in my hands, but perhaps I can describe what went wrong, when you look very close to or better into the lens.
On the glass or plastic parts of the lens elements in a lens, sometimes a mould can grow. For that there must be some moisture inside. When your camera is old, it is possible you once had it outside when it started to rain, or it was in a cold place for a longer time, so some damp could settle inside. If mould is settled on one (ore more) lens element(s) the damage is done. The interchangeable lenses from DSLR cameras can be worth bringing to a repair shop, but the system cameras and point and shoots, special when they are aged, are not worth repairing. Cameras are getting better and better, and in the same time the prices are going down, almost in the same pace.
I don't know how bad the blur is. But if you don't see a thing on the pictures you take, leave it and always put your camera at rest on a clean and dry place. If not the lens, but the pictures are blurred, perhaps something else is going on?

My lens is all blurry


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.

How can I clean out the inside of my lense?


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 .

How could I clean camera lens? The problem is I see a speck of dust in all my shots. Could I dismount the camera? Many thanks for your help.


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.

If parts of the person's face are in focus, and others are not, it is because your depth-of-field is too shallow. This is controlled by the aperture of the lens.
Use the "A" mode on your camera, for aperture priority, and set the aperture to f/5.6 or f/8. This will make the person's face completely sharp. You will, however, lose some of the blur in the background.
Also, be careful not to move the camera after focusing.
Happy shooting!

Hi there.
Sadly, point-and-shoot cameras are not designed to be disassembled and then reassembled easily. Therefore your best option is to take it to a store that specializes in camera repair.

I love my camera, but most of my pictures turn out blurry in places, unless the subject is standing perfectly still.


Hi. When parts of the subject are moving it is normal for the subject to tend to be be blurred in those places. Blurring is minimised if you take pictures in bright light because the 'exposure' (the time needed for the sensor to collect enough light to take the picture) is less. Also the 'sensitivity' of the sensor can be increased by reducing the ISO setting in the menu so that the sensor needs less time to take the picture. However ISO settings higher than 200 tend to more and more make the image a bit blotchy. The 'aperture' is also relevant and F2 (wide open) lets in more light than say F5.6 (narrower), so helps to reduce blurring too. Mainly you rely on bright light to minimise blurring if the subject moves, but there is also a 'sports' scene mode which might help. Indoors, you more often need to use Flash to get a good picture by providing more light, but flash does not usually reach far enough to have much effect out of doors, unless the subject is close by. In 'auto' mode the settings look after themselves but have a good look at the Instruction Manual and experiment with 'manual' settings to find out how the camera works and read a few beginner's aricles to make things more interesting. Most of all have fun! Regards

Fujifil FinePix S6500fd: How to focus the subject(blur the background)? Like this: http://sphotos.ak.fbcdn.net/hphotos-ak-ash2/hs604.ash2/155662_1475615262462_1596139557_31044751_765416_n.jpg


What you are asking about is called depth of field. Boiled down, it means that there is a certain amount of area in an image that is in focus, given the focal length of the lens, the aperture (size of the shutter opening) and some other factors. There's a lot of theory behind it, but you just want to know how to accomplish that creative blur behind the subject, right?

If your camera has the capability to choose the aperture, known as the f-stop, either with a manual mode or an aperture-priority mode, then this is pretty easy. The larger the aperture (size of shutter opening) the smaller the depth of field, which means only a small area is in focus. The aperture, or f-stop, is denoted with numbers like F/2.8 or F/8, etc. The lower the number, the bigger the aperture and the more background blur you will get. There is an inverse relation ship between shutter opening and speed, too. A big opening like F2.8 means a faster shutter speed, versus a small opening like F/22. Every lens is different, so your aperture options will vary.

If your camera does not allow you to choose the aperture, it may still have a "scene" setting you can use. A "portrait" or "night" setting usually has a bigger aperture than, say, a "landscape" setting.

Other factors also contribute to creating background blur. All else being equal, the blur increases as you move closer to the subject or as you zoom in on the subject with a zoom lens. Also, having greater space between the background and your subject increases blur.

So, to maximize background blur and create a shallow depth of field, you want to pick the largest aperture possible (smallest f-stop number), you want to get close to the subject and extend your zoom as much as you can, and you want to maximize the distance between the subject and the start of any background objects. Your success will depend in part on your camera and lenses.

If all else fails, you can also artificially create the background blur in software after the image is taken, but that's another story!

I use 50mm Nikkor with D300s. If I try to increase the aperture by 22 to get better depth of field it comes blur. why is that? Do i need to change the camera settings?


When you set the aperture to 22, you decrease the amount of light coming through to the sensor. Hence, you camera compensates by increasing the shutter time. With the decrease in shutter speed, you have a higher can of blurring the picture if you're holding the camera by hand. Try mounting on a tripod to keep the camera still. See if that helps.
