It is a zoom lens but it can be considered both a wide angle (at 18mm) and a telephoto lens (at 200mm) because it's zoom range is so huge. What is the difference between the two? 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.

I've heard it said that 50mm is the standard as far as lens focal length goes, meaning that at 50mm your camera will take a photo as close to how the human eye sees it, i.e. rev 2020.11.30.38081, The best answers are voted up and rise to the top, Photography Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us.

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. If the tiny focal length of a macro lens is likely to cause issues for you, it might be worth looking elsewhere. Why is "threepenny" pronounced as THREP.NI? To learn more, see our tips on writing great answers. Sometimes you can't step back further to get a wider view.

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. Let’s start with the basics: this is a noticeably lightweight and compact lens, designed for Micro Four Thirds format cameras and, therefore, has a 35mm focal length equivalence of 300-800mm. You could pack a lot of lenses and select the one you want for the situation you want, or you could carry a zoom 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? The term "telephoto" is much abused because it … It only takes a minute to sign up.

(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.
