Zoom Lens
What is the difference between a regular "zoom" lens and a telephoto lens?
Is there one? I am new to photography, and the only difference I see between them is that a telephoto lens appears to have a much larger len on the far end than a regular zoom lens.
I'm a noob, so sorry for the potentially dumb question.
Thanks for the answers.
"Telephoto" refers to a specific way to design a lens which allows the lens to be physically shorter than it's actual focal length. Most lenses longer than 75mm or so(for 35mm cameras) are a telephoto design, although there are lenses longer than this that are not telephoto lenses.
A zoom lens is a lens on which the focal length can be changed. Technically, in order for a lens to be called a zoom lens, the point of focus needs to stay the same as the focal length as changed, although few lenses do this.
It's possible to have a zoom lens which uses a telephoto design-this is very common for zoom lenses where part of the focal length range is greater than 75mm.
It's also possible to have a zoom lens which does not use a telephoto design.
So, to answer your question, telephoto and zoom are terms which have totally different meanings, and are not mutually exclusive.

Prime Lens Vs Zoom Lens – Which Is Best?
So, you’re wanting to get a new lens, but you’re not quite sure whether to buy a prime lens or a zoom lens. Both types of lenses have their advantages and disadvantages, and you want to make sure you make the right decision and get the lens which best fits your photographic needs.
In case you didn't already know, the main difference between a zoom lens and prime lens is that a zoom lens enables you to adjust your focal length within a certain range (for example 18-50mm), whereas a prime lens has a fixed focal length.
So you might be wondering what the point is of using a prime lens. Surely if you have the choice between a lens with flexibility and one with no flexibility, then surely the flexible one is the best one, isn’t it? Well, it’s not really as straightforward as that, because prime lenses do have some advantages. To begin with, they are lighter than zoom lenses because they have less moving parts. Mechanically speaking, they are simpler.
In addition to this, prime lenses usually have wider apertures. The aperture of a lens determines how much light the lens lets in at any one time. Aperture ratings are in ratios, for example 1:3.5 or 1:2.8, but usually when buying a lens you will see it shown without the 1 in front of it, for example 3.5. Lenses with lower aperture numbers are more expensive, as a lower number means a wider aperture. Having a wide aperture produces a shallow depth of field, meaning that only a small distance range is in focus. A narrow depth of field (a wide aperture) would be great for close-ups of flowers where you want the background blurred, whereas a large depth-of-field (a small aperture) would be ideal for landscape photos.
Okay, so how about the zoom lens?
Well, a zoom lens will give you a bigger range of distances to compose your image. This means that you don't need to move closer or further away from your subject to get the picture you're after. It can also be great for taking shots of wildlife, because you can zoom in without having to change your position, so you will be less likely to scare the animal away.
The best way to decide which type of lens is right for you is to ask yourself what type of photography you are going to be doing. If you are going to be photographing a scene which remains still, such as a landscape scene, then a prime lens could be a good choice. If on the other hand you want to photograph things that are moving, such as animals, people, or sports photography, then a zoom lens is a must.

It’s not always easy trying to make this kind of decision, but whatever you decide, a Canon EF 85mm or a Nikon 17-55mm 2.8 Lens are good examples of the type of lenses that will always be useful to have as part of your photography kit.
