Ok, still new to true photography, and I want to know exactly what's up with lenses. Are all lenses compatable with all cameras? I have a Canon G6, what all will work with that? What all would I use the lens for? Finally, what can I expect to pay for a good kit?

I know it's alot, but it would really help if someone could explain this to me. Thanks!

Your Canon G6 does not have interchangable lenses. You can buy add on lenses that will give you a close up or telephoto aspect.These add-ons will attach to your exsisting lens. The Cameras that have interchangable lenses are called SLR's (Single Lens Reflex), also DSLR (Digital Single Lens Reflex). With these cameras, you basically purchase the body or a kit that includes a lens. The benefit is that you are not limited to one lens, you can buy the lenses that will cover the range you are looking for, such as (28-75mm or 70-200mm).

This is also a drawback to the SLR cameras. Lenses are expensive, if you have a few, it's cumbersome to carry around. However your results will be alot better than a point and shoot camera.

Right now the most popular dSLR is the Canon Digital Rebel 350D or the Nikon d70.

Here is a site that will give you good information for both:

Canon Digital Rebel 350D

Nikon d70

DO the research, a dSLR is a big investment, your looking at spending between $800 - $1200. That's just for the kit. Lenses are a different story.

Find some equipment that you are looking into and then search the forums. If you can't find the info, post your questions. There are many helpful people on this site!

To give you better information on lenses, just need to know what kind of pictures you will be taking mostly; portraits, landscapes, Macro, etc.

This will give a better idea of which direction to go.

I think for digital cameras, either the maker (Canon) or aftermarket companies make lenses as adaptors that go over your lens specifically to get a wider coverage (lower focal length than 50mm, e.g. 28mm) or increase it's telephoto coverage (higher focal length than 50mm, e.g. 200mm). I'm sure you can check the Canon's site or do an internet search and find some. The adapter will fit over your lens and in theory degrade the optical performance, although it may not be enough to physically see them. It may make your camera less sensitive to light, requiring a slower shutter speed or increased light sensitivity (higher ISO) to compensate, which also has it's downside, manily in increased chance of motion blur and grainier image, respectively.
A lens that is wider will let you see more in terms of field of view. A telephoto adapter will let you get closer to a subject without actually getting physically closer to the subject.
Wide angle lens usally are used for things such as landscapes where a big field of view gives a nice paronamic view where everyting near and far is in focus, while a telephoto lens tends to be used for portraits where the subject is in focus but the background is blurred out to put attention on the subject.
Hope that helps.
