I am just wondering if lenses are actually interchangable between different brands and models of digital cameras, or if you actually have to buy different lenses for every camera?? Sorry if this is a really silly question!! Thanks for any help!!!:-)

Non DSLR (Digital SLR Cameras) have permanently attached lenses (not removable or interchangable).

To get a model with removable lenses, you'll need to step up to a true DSLR. The two least expensive models are the Canon Digital Rebel/EOS-300D (lists at $899.00) and the Nikon D70 (lists at $999.00). This is for the body only with no lens. They also come in a kit with a lens for a little more.

Within the same manufacturer, lenses are usually interchangeable between their DSLR models, with some exceptions.

Now, some non-DSLR models can takeadd-on lenses to increase the focal length (teleconverters), or give you a wider wide angle (wide angle converter lens).

Some models can use these, and some cannot. With models that can use them, you will usuallyneed an optional adapter designed to let you use these add-on lenses (although some models have built in filter threads that can be used for this purpose).

You will also need to find lenses that have the same filter thread size, that their adapters specify (52mm, 58mm, etc.). This varies between models. Lens quality also varies widely.

BTW, there are some drawbacks to an add-on lens with most models. For example, if you buy a 1.7x Teleconverter lens (designed to multiply the focal length of the cameras lens by 1.7 times), then you will usually have vignetting (darkening of corners) at some focal lengths (usually at the wider lens setting). This can make it look like you are taking pictures through a tunnel. The amount of vignetting you have, will vary widely between camera models ofcameras and converter lenses.

There are some better third party add-on lenses that can be used on several different types of cameras (as long as the camera has a filter thread)...but with some models (as stated above) you can get vignetting. Here's a page for Raynox lenses, and if you click on a lens you can see what cameras that lens is compatible with (as well as samples):


These lenses can also be added on to SLR cameras, but with that type of camera it would be better to get the right kind of dedicated SLR lens.
