The focal length of the lens is the distance between the lens and the image sensor when the subject is in focus, usually stated in millimeters (e.g., 28 mm, 50 mm, or 100 mm). In the case of zoom lenses, both the minimum and maximum focal lengths are stated, for example 18–55 mm.
What mm is a good zoom lens?
Telephoto lenses between 70 – 200mm 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.

How does mm relate to zoom?
The zoom amount(x) or capability of a lens is the ratio of the maximum:minimum focal length(mm) of a lens. For example, an 18-55mm lens has 55/18=3x zoom (approx.) and a 70-300mm lens has a 300/70=4.3x zoom (approx.)
What does mm on a lens mean?
focal length
Millimeters, or “mm” for short, is the standard unit of measurement for the focal length of a lens. So when you see “mm” following a number or a pair of numbers on a lens, you will know that the number refers to the focal length (single number) or focal range (pair of numbers).
What does a 50 mm lens do?
50mm prime lenses also have a much wider aperture than zoom lenses — with some 50mm lenses going all the way up to f/1.4. The extremely wide aperture lets in about three to four times as much light as your regular kit lens, helping you shoot clear pictures in even the lowest light conditions.
What is a 58mm lens used for?
Professional photographers often use 58mm lenses on a crop sensor—around 85mm on full frame—to shoot portraits.
How many mm is 10x zoom?
Now, at MWC 2019, it has revealed that the phone will be officially out in the spring. Having a 10x zoom on a camera phone is no mean feat: it means the device will offer a zoom ranging from 15.9mm to 159mm (the equivalent of).
What is 50x zoom in mm?
24-1,200mm
The 50x optical zoom alone is the focal length equivalent of 24-1,200mm on a full frame body.
What is 1X zoom in mm?
A 1X optical zoom would be a given focal length divided by itself. 35mm divided by 35mm is 1X. In photography we call this a prime lens.
What does 10X zoom mean?
An optical lens has a set of many individual lenses which move to enlarge the image. 10X means, the lens has the power to enlarge an image 10 times between normal focal length and Tele focal length.
How many mm is 4x zoom?
For example at 2x zoom has a focal length equivalent of 35mm to 70mm and a 4x zoom has a focal length equivalent of 35mm to 140mm.
What is a 30x optical zoom in mm?
30x optical zoom. Extend your reach to the max with this fast 27 mm – 810 mm f/2.8-5.6 Carl Zeiss Vario Sonnar T* lens. The 30x magnification range is nothing short of incredible, allowing you to zoom up to distant subjects while still maintaining the clarity that only optical zoom can provide.
Which lens is better 35mm or 50mm?
You would see that the 50mm gives you a shallower depth of field and better bokeh. The 35mm, on the other hand, will fit more into the frame, making it more suitable for landscape and indoor photos.
What does 100 mm lens mean?
100mm is the length of the lens. In general, longer lenses magnify more than shorter lenses. 2.8 is the maximum f-stop of the lens. The f-stop is actually the ratio of the length of the lens to the width. Smaller numbers indicate a larger opening.
What mm is best for portraits?
For portrait photography, 50mm lenses are great for full-length and waist-level portraits, both on location and in the studio. This is thanks to the wide field of view compared to an 85mm or 135mm lens, and you don’t need to be too far away from the model to achieve these crops.
What mm is the human eye?
The typical minimum focal length of the human eye is 22.7 mm (2.27 cm). The typical maximum focal length of the human eye is 25 mm (2.5 cm). Therefore, the nominal focal length of the human eye is generally taken as 22 mm (2.2 cm).
What is 35mm lens best for?
The 35mm is a lens that allows you to capture many different types of camera shots and angles. It’s wide enough to capture background elements, but close enough to shoot more intimate shots like coverage and portraits.
What angle is 50mm?
Field-of-view (also known as FOV)
| Lens Focal Length | FOV (Angles in degrees) | |
|---|---|---|
| 35mm | 54.4 | 63.4 |
| 45mm | 43.6 | 51.4 |
| 50mm | 39.6 | 46.8 |
| 55mm | 36.2 | 42.9 |
What is a 30mm lens used for?
As you can see, the 30mm lens allows more content into the photo. This is great if you’d like to feature a beautiful background or if you’d like to have the person in your portrait be shown from head to toe and don’t have much room to physically back away to take the photo.
What do you use a 300mm lens for?
Focal lengths such as 300mm or 400mm would be a large, heavy telephoto lens for taking photos of birds or airplanes. Just remember – a small number is wide, a large number is telephoto. Two numbers together, e.g. 35-105mm, means that the lens zooms from one focal length to another.
