- The first number indicates the range of focal lengths available in millimeters, while the second indicates the lens speed (in the case of the 1.4/50 designation, the second number indicates the reverse). For example, the first number or set of numbers specifies the range of focal lengths that are accessible in millimeters. It is listed after the minuscule “f” and the slash to indicate the lens speed.

What does f 1.8 lens mean?
Aperture sizes are expressed in terms of f-stops. A high f-stop, such as f/22, indicates that the aperture hole is extremely small, while a low f-stop, such as f/1.8, indicates that the aperture hole is quite large. To illustrate, we’ll utilize the new iPhone 11 Pro, which has three cameras with varying focal lengths and apertures, each with a separate focus length and aperture setting.
What do the MM numbers on a camera lens mean?
The number of f-stops represents the size of an aperture. In photography, an aperture hole that is extremely small (f/22), and a large aperture hole that is very large (f/1.8), is indicated by the use of an f-stop. To illustrate, we’ll utilize the new iPhone 11 Pro, which has three cameras with varying focal lengths and apertures, all of which may be used simultaneously.
What does 18 55mm mean in lenses?
A focal length range is represented by the numbers 18-55mm. It implies that you have the ability to modify your focus length. The widest angle is 18mm, and you can zoom in to 55mm with the camera’s zoom feature.
What does f 2.8 lens mean?
It indicates that the aperture ring has been opened to f 2.8. Essentially, this implies that you will get more light to the sensor and more bokeh, but you will have a smaller depth of field (The area in focus). The majority of the time, this type of wide open aperture is employed for portrait photography.
Is 2.4 or 2.8 aperture better?
There isn’t much to say. A lower F-stop number correlates to a bigger opening of the aperture, which means that more light is captured. This implies that you will be able to get properly exposed images without having to use a higher ISO setting or a longer shutter speed.
Is 1.4 or 1.8 lens better?
The 1.4 is a superior lens than the 1.8, by a wide margin. The 1.4 has a quiet motor built into it, which means you can barely hear the lens focusing while it is on. This is beneficial since it makes photographing a client more fun because you won’t have to listen to your focusing motor while you’re shooting. The 1.4 is also noticeably crisper than the 1.8, which is a plus.
What does a 70 300mm lens mean?
The 70–300 mm lens is a zooming telephoto lens with a focal range of 70–300 mm. As a point of comparison, a full frame 35 mm film is utilized. If you’re using an APS-C sensor, the length is 1.5X longer, or 105 – 450mm in this case. For a 35mm frame, a “normal” field of vision is regarded to be 50mm or 2 inches wide. Wide angle lenses are those with focal lengths less than 35mm.
What does 300mm lens mean?
For photographing birds or airplanes, a telephoto lens with a focal length of 300mm or 400mm would be a hefty and heavy piece of equipment. Just keep in mind that a small number represents wide angle and a high number represents telephoto. The combination of two numbers, for example, 35-105mm, indicates that the lens zooms from one focal length to another.
What does 24mm lens mean?
A single number, such as 24mm, signifies what is known as a prime or fixed lens, which means that it does not have the ability to zoom in or out of the image. A lens with a single focal length—in this example, 24mm—is developed and optimized for that focal length alone.
Which lens is better 18 55 or 50mm?
The difference in aperture between these two lenses is significant, as you can see here. F/3.5-F/5.6 on the 18-55mm lens, whilst the 50mm lens features a fast F/1.8 aperture on the 50mm lens. The 50mm can perform better in a wider range of settings because of its larger aperture.
What is the 70 300mm lens good for?
In addition to covering a wide focal length range of 70-300mm on Nikon DSLRs with a built-in focusing motor (105-450mm equivalent on DX-format cameras), it’s a fantastic choice for most daytime telephoto subjects, from portraits to wildlife photography, on Nikon DX-format cameras. Bring the action closer to the viewer by including vibrant, lifelike detail.
What is a 50mm lens good for?
50mm lenses have a quick maximum aperture and are therefore considered fast lenses. F1 lenses are often used for the most basic 50mm lenses. 8 – This is an extremely large aperture. In other words, they are excellent for low-light photography (e.g., low-light portraiture or interior shooting), as they enable more light to reach the camera’s sensor than traditional lenses.
What’s the difference between f 2.8 and f4?
Obviously, the most noticeable difference between an f/2.8 and an f/4 lens is their “brightness,” or the greatest quantity of light that may be allowed to reach the sensor through each lens. Typically, an f/2.8 lens would be capable of producing a shallower depth of focus (and, thus, more background bokeh), compared to that of an f/4.0 lens.
What does 15 55mm lens mean?
The focal length of the 18-55mm lens is between 18mm and 55mm, as indicated by the name of the lens. Varied manufacturers have different specifications, but the typical aperture range for a 15-55mm lens is between f/3.5 and f/5.6 on most models. When zoomed in to 18mm, the lens is capable of a larger aperture; hence, when zoomed in to 55mm, the maximum aperture is f/5.6.
What does the 50mm lens mean?
The focal length of a lens is measured in millimeters (mm). 50 mm is equal to 50 millimeters, which is approximately 2 inches in length. In the context of photography, this measurement serves as a broad description of how much magnification a lens will provide.
