The term "telephoto lens" has a particular technical meaning in terms of lens design, but in common usage it refers to a lens with a long focal length. The benefit of telephoto lenses is virtually lost in short focal length lenses (typically under 100mm) but is quite apparent in longer ones. Zoom means that they can change how far they are looking at or prime means they have a fixed amount of magnification and can't be altered. The telephoto lens works much better than a digital zoom, which essentially enlarges and crops the photo. Animation by Stefan-Xp from Wikimedia Commons, CC-BY-SA, both pics by Koyaanis Qatsi. 2.

So to sum up, a lens with- Fixed focal lengths/prime lens: this is simply a lens that has only one focal length, for example, 18mm, 28mm, 70mm, 300mm.In concrete terms, you have a shooting angle that always remains the same. :) I was hoping for a completely lay explanation. Why would I want one over the other? So, you can have a prime telephoto lens that is not a zoom, and you can have a wide angle zoom lens.

It’s a case of horses for courses, and each type of lens has its own strengths and weaknesses and is invaluable for different types of photography. Zoom lenses currently come standard nowadays as they provide the best combination of flexibility to price. Basically if you're focal length is below 50mm you're in wide angle mode and if you're above 50mm you're in telephoto mode. There are different lengths for different users. So, if you want the sharpest images possible, you are looking at using a prime (not a zoom) lens. When you buy a zoom lens, you are buying a large range of focal points in one lens, where a telephoto lens is only made to have one focal point per lens.

Why do photographed objects in the distance appear smaller than they do by naked eye? (Note: this is part of why interchangeable lenses on rangefinders and mirrorless systems can made more cheaply - they can use simpler designs for their shorter flange distances). Can you explain?

(Same Up To ~0.0001km), I don't understand Ampere's circuital law. It comes at the expense of aberrations, less light getting through the lens (requiring longer exposures), and other distortions. Need help with solve a system of delay differential equations. With a Nikon F mount, the flange distance is 46.5mm. So, you can have a prime telephoto lens that is not a zoom, and you can have a wide angle zoom lens. but #4 is kind of a deal breaker. Telephoto and telephoto zoom lenses are very popular among sports and wildlife photographers as they are the ones who need extreme focal lengths.
