They tend to use large apertures and allow a lot of light to enter the lens which makes them fast in low light conditions. Standard lenses are the popular choice for a wide range of photography including portraiture, nature and low light situations where the photographer can not use a flash or is looking to capture the scene with available light.
Telephoto lenses between 70 — mm are very popular lenses for portraiture and product photography as well as nature and wildlife imagery. They allow the photographer to produce close crops on the subject. In the case of portraiture a telephoto allows the photographer to take the photo at a distance that does not intrude upon the subject. These lenses provide a good range for wildlife and sports photography where the photographer is limited as to how close they can get to the subject.
Close-up photography uses a specific range of lenses that allow up to reproduction. These lenses allow the photographer to focus very close to the subject and reproduce them at a life-size ratio on film or an imaging sensor. These lenses are popular for subjects such as flowers, insects and small products. By clicking Sign Up, you are opting to receive educational and promotional emails from Nikon Inc.

Or is it measured in some other way? I'll be traveling to the arctic circle in a few months and will be taking pictures of the Northern Lights at night, low-light snow covered scenery during the day, and hopefully the Milky Way if I can swing it.
If you haven't guessed by now, I am a complete novice and really appreciate people like you who have taken the time to explain things in plain old English. Thanks for your input! Hello David. This post is very informative. Thank you for writing it. I need some help with the lenses. The Nikon D has a crop factor of 1. Should I still go for 50 mm lens? And apart from that, what other lens would you recommend for food photography? Please consider the 1. You can ignore the crop factor unless you are using a film lens with your digital camera.
All digital lenses have already done the conversion for you. I have recently bought a Canon Rebel T6 D with the kit lens mm only. I am more interested in clicking portraits. So which lens should I add to my camera? A mm Tele lens or 50mm f1. For portraits, I'd definitely go with the Prime lens because it has a wide open aperture that means you can get a much more pleasing 'blurry background' look than is possible with a telephoto. Yeah I'm just starting out again with amateur photography got a Canon Rebel t6i and I was thinking about getting a millimeter single Focus lens what the amateur 1.
They are called 'fast lenses' because they allow you to use a faster shutter speed. I have a mm sigma lens, you said to take portraits it is best taking we a 70 or mm focal length.

It will depend on how you define the "zoom factor". Is it field of view or focal length? Nick Bedford Nick Bedford 9, 3 3 gold badges 27 27 silver badges 40 40 bronze badges. Just focal length, I'm only considering the magnification of the image.
Actually, I think it is linear, isn't it? That's because zooming is mathematically like cropping, so each doubling of focal length is halving dimensional field of view in a very straightforward way. Nick Bedford, mattdm - I'd stress that the actoal FoV change is indeed nonlinear. For relatively long focal lengths, the angles are small and the change is approximately linear.
However, as you get to the wider side, the angles become large and the mapping from focal length to angle of view is nonlinear. That said, I never saw a definition of zoom range w. Update the graph to have a logarithmical x-axis, and you would see a straight line : — Pete.

Olin Lathrop Olin Lathrop You can make it stronger, the 2x and 3x zooms are nearly always much higher image quality and often build quality than the 8x and 10x zooms from the same brand. The classic zoom in both the Canon and Nikon lines is the , just a bit under 3x. Nearly all 8x and 10x zooms are consumer-level products. They are designed to a price, with image quality a lesser design criteria.
Scot Cannon Scot Cannon 1. I think you may have interpreted the question incorrectly. The OP is asking about some commonly used notations namely focal length and times zoom and not any other optical properties of zooming. Key: Lens is 4. Hope this helps.
Jill Rapley Jill Rapley 1. I assume you mean Canon SX50, which has a sensor 6. That means that a mm lens on the Sony will give a horizontal field of view roughly like that of the Canon set to 55mm.
The aspect ratio is different, though, so the diagonal or vertical equivalence is a little different. Photo of the Week. Submit your photo Hall of fame.
