Broken lens on digital camera?
If it is not a removable lens, trash it and buy a new camera. It will cost more than the price of a decent replacement to fix it. The above refers to actual cracking or scratches on the lens itself. But if you're experiencing problems with the lens barrel extension mechanism (a lens error), then there are some things you can do to correct the problem. Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ... There are several things that you can do to try to correct it. These home fixes seem to work for less than 50% of the lens errors. If the camera is out of warranty, and if professional repair will cost more than the value of the camera, then they're worth a try.

Answer . Yes. There are adapters avalable that let you do this. But, you will have to focus manually.. [Spelvin adds] In addition, because such adapters generally serve as… a spacer between the rear of the lens lens and the camera body, you may lose the ability to focus at infinity.
It is a lens that mounts on the end of your camera lens. Some are wide angle adaptors (0.75x is an example) and some are multipliers (1.5x or 2x) which move you half the dista…nce to the subject you are shooting.They can be handy adaptors, but can also reduce critical focus in your pictures, or degrade sharp focus.There are also lens adaptors for digital SLR cameras to use lenses from another type of camera.A lens adaptor could also screw onto the end of a lens to allow filters of another size to be mounted in front of the lens.---- Just an added note: Although the principle is the same, not all adapters mount on the end of the camera lens. Some adapters mount to threads on the body which may be hidden by a removable ring. So the camera may not always appear to have threads when it does, if you know where to look. Check the manual.
Depending on your camera, lenses are available or not available.. Nikon, Canon, Olympus etc., all have very good zoom lenses for their cameras. You will also find good lenses… from Tamron, Sigma, and Tokina, that would suite your requirement. However, I am assuming that you have an SLR camera...
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that uses an automatic mirror system and pentaprism or pentamirror to direct light from the len…s through the viewfinder eyepiece.. Cheep!. Fixed lens probably means fixed focal length. The lens (camera) cannot change focus. The manufacturer picks a compromise focus position that often gives somewhat focused pictures between maybe 7 feet and infinity.. It's also possible that it is referring to a fixed aperture. That is, it doesn't have a way to change the size of the opening behind the lens to control how much light gets in.. Cheep cameras often don't have either of these features.
The Canon EF 1200mm f/5.6L IS USM Super Telephoto Lens costs US$120000
To clean the lens of a digital camera, firstly avoid touching it with your fingers. Carefully blow off any grit and loose dust particles, then lightly wipe the lens with a so…ft, dry cloth or special lens cleaning paper. If necessary, use a tiny amount of lens cleaning fluid, but only put the fluid on the lens cleaning paper, not straight onto the lens itself. You can also use a microfibre cleaning cloth, or other soft cotton. Avoid using materials like paper towels, napkins or facial tissues.
Be sure that the lock is not engaged. Grasp the lens firmly on a portion that is fixed (does not turn). Grasp the camera in the other had. Firmly twist the lens in the "off" d…irection (usually counterclockwise) increasing pressure gradually. It may also be possible to loosen the lens by holding an air can upside down and squirting the liquid onto the area that seems to be binding the most. If you do this, use only a short squirt, and don't repeat it. The spray will cool the metal and may cause it to contract enough to loosen, but cooling things too much may cause condensation inside the lens. This is the sort of thing techs do but don't tell customers about. If you try the air can DO NOT GET THE LIQUID ON YOUR SKIN OR IN YOUR EYES. It is extremely cold, and will cause frostbite.
It focuses the light entering the camera onto the sensor.
The lenses are very meticulously assembled with the utmost of precision. Repair of such is best left to those who possess the certifications (experts) for this kind of service…. You should not be attempting this repair on your own in your garage bench shop. But if you must try, such as if the repair costs exceed the value of the camera, many people have reported success with the simple repair techniques outlined in the below listed "Related Link".
It depends on the camera. If it has detachable lenses, there should be a variety of zoom lenses available. Vivitar and Sigma are good manufacturers, and of course your camera …manufacturer's offerings are the best choices of all.
The long answer depends on what's wrong with the lens, but the short answer is easier. If you are not a trained technician with the proper tools, you don't.. An exception is …"lens errors".
