The first number or pair of numbers specifies the range of possible focal lengths in millimeters, followed by the second number or pair of numbers. You can identify what kinds of angles of view a specific lens can handle based on this information. Lower numbers indicate a broader viewing angle. As a result, a standard 18-55mm DSLR lens may “zoom” from medium-wide views all the way out to the beginning of the telephoto range.

What do the numbers on my camera lens mean?
It is measured in millimeters (mm), with the higher number indicating more zoom and the lower number suggesting that the lens may be utilized for broader images. A number less than 30-50 mm will allow you to see a larger area than you would normally be able to, while higher numbers suggest that you will be able to focus on a narrower portion of your view.
What do the numbers 18 55mm refer to on a camera lens?
The greater the number, the greater the amount of zooming you can do. 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 a 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.
What does 1.4 mean on a lens?
The maximum aperture of an f/1.4 or f/1.8 lens is regarded to be “fast,” since it allows more light to pass through than a lens with a “slow” maximum aperture, such as an f/4.0 lens, which is considered to be “slow.” As a result, lenses with high apertures tend to be more expensive.
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 is the difference between 18 55mm and 55 200mm?
The 18-55mm lens is the standard or “kit” lens. The focal length of the lens is indicated by the number. The 55-200mm lens is a super zoom lens. In LeMan’s terminology, the bigger the number, the greater the zooming effect is.
What does a 75mm 300mm lens do?
Telephoto zoom lens with a small footprint. Sport, animal, and portrait photographers will find this 4x telephoto zoom lens to be an excellent choice for their projects. For the same reason as other long-telephoto lenses, the EF 75-300mm f/4-5.6 III compresses perspective and allows photographers to narrow the depth of focus.
What do the numbers F 3.5 5.6 refer to on a camera lens?
If there is a range of numbers after the slash, as there is for example in “18-55mm f/3.5-5.6,” that means that the lens has a lens speed of f/3.5 at the 18mm focal length, but a lens speed of f/5.6 at the 55mm focal length, and if there is no range of numbers after the slash, that means that the lens does not have a range of numbers after the slash. Because of this, its lens speed evenly transitions between these two extremes.
What does 1 1.8 mean on a lens?
This indicates that the diameter of the aperture is equal to the focal length divided by 1.8, which is the focus length divided by 1.8.
Whats a slow shutter speed?
What is a Slow Shutter Speed, and how does it work? A lengthy shutter speed is often between one and two seconds or higher. A slow shutter speed, on the other hand, can refer to a fraction of a second, such as 1/2 or 1/4 of a second.
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 general description of how much magnification a lens will provide.
What does F4 mean on camera lens?
F4 is referred to as an f-stop. The aperture, or how open the lens is, is indicated by this number. It has an effect on the depth of field and the quantity of light that reaches the lens/camera sensor. The greater the width of the hole, the greater the amount of light that can enter, resulting in a brighter image. It is represented by the letter “f,” for example, f/1.8, f/2.0, f/2.8, f/3.5, and so on.
Why are 1.4 lenses so expensive?
Briefly stated, the full frame 35 f/1.4 lens is more expensive than the full frame 35 f/1.8 lens because: the f/1.4 lens is a full frame lens, it projects a bigger image circle, and it also has a larger aperture, all of which make it a more challenging lens to design and build.
What does 1.2 mean for a camera lens?
A focal ratio of 1:2 is the same as an aperture of 2.0 or 2. The f-stop is another term that is often used. It is the maximum aperture that your lens is capable of producing. Lower numbers signify quicker lenses, and faster lenses are often more adaptable since they allow you to shoot images in low-light circumstances, which is more common with DSLRs.
What is the Canon 50mm lens good for?
Compact and lightweight, this lens makes an excellent walk-around lens. In terms of introduction into the world of EOS prime lenses, the Canon EF 50mm f/1.8 STM is a fantastic choice. With an effective focal length of 80mm on APS-C cameras and 50mm on full-frame cameras, it’s a fantastic prime lens for portraiture, action photography, and even night photography due to its wide aperture.
