Here are some more information for Lens Only:
The camera lens is your hand held eye on the world. If you look at the world through dirty glasses, or fog, your image is unclear. The same is true of a camera lens. If it's dirty the image you obtain will be unclear. You'll have to clean it and do so carefully so that you don't leave it dirty. If you have a delicate lens on your camera, you only want to clean it when it is very dirty. There are ways to clean the lens without damaging it or your camera.
The first thing to do is remove the dust and dirt that has adhered itself to the lens. Use a brushing tool for this. It is a special brush, much like a thick artists brush, often with a rubber air blower on the end. Gently brush the lens while squeezing the rubber end. This will dislodge the tiny dust particles that have collected there. Do not use too much pressure as there may be harder particles present that can scratch the lens. That would be much worse than the dirt itself. The bottom line is to be careful.
In most cases this will be all you have to do. Stopping the cleaning process right then and there won't expose your camera in further danger. You never want to put your camera in further danger of damage. However, there are also oils that will build up on the camera lens that require more than brushing to remove. For this use a clean, soft, high quality cloth. There are also special cleaning tissues available from camera retailers. They come in different quantities. If you use real cloth, make sure you wash it between uses. It only takes on tiny left over dirt particle to permanently scratch the lens.
There are two types of liquid cleaners for cleaning camera lenses. If the film on your camera lens is water soluble, you can use distilled water available at your local grocers. The second type is with you as you read this. It's your breath. Using your warm breath on the lens creates a type of distilled moisture. The point is that the liquid must be clean and free of harmful minerals. If you use distilled water, pour a very small amount onto your cleaning cloth. Never, ever pour it directly onto the camera or lens. The water could easily seep inside the camera and permanently damage it. Always err on the side of caution. It's better to repeat the cleaning process with too little moisture, than to have too much water on the lens.
There may be oils present that require more aggressive cleaning. For this type of grime you'll need regular alcohol. Be sure that it is 100% pure alcohol. Anything with additives could damage the lens. Don't use things such as paint thinner or toxic liquids. The reason for this is that the camera is close to your face. Camera retailers also sell special camera lens cleaners. These are good for lenses that are saturated with oil based film. Follow the same procedures as with the other liquids.
All cameras, from that old Browning film camera you got as a kid, to large Single Lens Reflexes and today's Digital SLR Cameras have lenses. They all require cleaning at some point in time. I cannot over-emphasize the importance of using due care when it comes to cleaning your camera. That sophisticated piece of equipment was an expensive investment. Permanent damage would be far worse than a small amount of dirt on your lens. With proper care and due caution your camera will last, and will always be ready for that special moment.

Creative Photography: Choose the Right Lens for the Job
A new digital camera comes with a multitude of features, but one of the first things we consider is the quality and power of the lens. But how many of us really understand what can be acheived by creative use of lenses?.
The difference between a wide angle lens and a telephoto lens is about more than just magnification. To get the most out of your lenses, you also need to understand how they affect depth of field and perspective.
You already know that the telephoto lens enlarges everything in the picture. But did you also know that when you zoom in, or attach your large telephoto lens, you also reduce the depth of field around the subject? This is a great method for eliminating a distracting background from your photo. The result is twofold: the narrow field of view minimizes how much of the background we can see, and the small depth of field ensures it will be completely out of focus.
So when photographing subjects like people and animals, using your telephoto lens (or zooming in with your zoom lens) is often the best approach. The result will be a very three dimensional effect, with the subject appearing to emerge sharp and clear from the blurry background.
On the other hand, your wide-angle lens does just the opposite. It certainly does a lot more than just make everything appear smaller. The wide angle lens takes in (as the name suggests) a much wider angle of view, and it has a much stronger depth of field than a standard or telephoto lens. That means that not only will you see a lot more of the background in your photo, but it will also be much more focused.
Consequently the wide-angle lens is not so good for portrait style photos, because the background is too distracting. On the other hand, it is excellent for landscape pictures, especially when you have objects both in the foreground and background that you need to keep in focus.
The other aspect of your choice of lens is perspective, which is a lot harder to explain without pictures, but I will give it a go.
Have you ever watched a cricket match on television? (If you are from the United States substitute baseball here). You will often see a close-up of the batsman, and notice that the wicket-keeper (shortstop) appears to be standing only a few feet behind him, and that the crowd in the grandstand seems only a short distance further away. When you see a side-on view, you may be surprised to see that the wicket-keeper is standing about ten meters behind the batsman, and of course we know that the grandstand is a good 60 meters or so further back. So what's going on?
The answer is simple. The very large telephoto lens used for the close-up shot tends to make objects at different distances seem much closer to each other than they really are. In short, it compresses the natural perspective, making people separated by some distance appear to be quite close to each other.
This principle also applies to landscape photography. Imagine a scene with a tree in the foreground and a mountain range in the distance. By standing a long way from the tree and shooting it with a telephoto lens, you will also enlarge the mountains in the background. As a result, they will appear much closer to the tree than they really are.
Now imagine taking the same scene with a wide-angle lens. By standing a lot closer to the tree, you can photograph it in such a way that it takes up the same amount of space in the composition. However, by reducing the scene to fit the tree in the frame, you also reduce the background...making it appear much further away than it really is.
In this way, the wide-angle lens does the opposite of the telephoto lens. It exaggerates the perspective, making objects at different distances appear much further apart than they really are.
Put simply, the end result of these two approaches is this; the telephoto lens adds prominence to the background, which will appear relatively large in your photos (albeit with depth of field issues in some cases). The wide-angle lens adds prominence to the foreground, making the background appear much smaller and more distant.
Thus by simply changing your choice of lenses, you can dramatically alter the impact of your photos. Imagine the creative possibilities; you have the power to control how the viewer sees not only your subject, but how it relates to the surroundings at the same time.
This is a tough subject to explain without pictures, but hey - you have a digital camera. Why not step outside right now and try out a few of these ideas. Or if you are feeling lazy, sit down and watch some sport on telly. It may actually teach you something about photography.

why do you use lens paper only once?
i dont get why?
Aside from the problems with the oils from your skin, another big problem with reusing lens tissue is the grit, dust or salt that you are wiping off the lens with it. These are abrasive, and they will stick to the lens tissue.
The front elements of camera lenses, are highly polished, and often have a treatment called multi-coating applied to them. This is the colourful reflection you can see on the lenses of cameras, binoculars and some glasses. This treatment helps light go through the lens, and not reflect back off (makes for brighter more colourful pictures).
So if you took your lens tissue, which still has all the oils, dirt, dust and filth you wiped off earlier, and rubbed it around and round your lens, you'd be scratching the multi coating or the glass of the lens. This will slowly but surely destroy the optical quality of your lens.
Most lens paper is very fine and delicate, and wouldn't really hold together if you used it more than once.
Its also so cheap, that it isn't worth trying to use it more than once.
