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 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 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.
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.
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.
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.
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 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 is a 75 300 mm lens good for?
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 is 300mm lens good for?
So, what is the purpose of telephoto and superzoom lenses, such as a 70-300mm zoom? They work best when you want to get up close and personal with a faraway subject. It may be a structure on the horizon or a face among a sea of faces in a crowded place. They’re ideal for wildlife photography, especially when you’re unable to get near to the creatures you’re photographing.
Which is better for portraits 50mm or 85mm?
Longitudinal focal length (reach) When photographing portraits, some photographers prefer to get up up and personal with their subjects, in which case a 50mm lens is the preferable choice. Others like to keep the subject at a distance, and an 85mm lens will perform admirably in this situation. If you take a lot of headshots, an 85mm lens is certainly a better choice for your needs.
Is the 50mm 1.8 worth it?
Yes, without a doubt. When compared to other lenses in the same price range, the 50 f/1.8 offers exceptional value for money, thanks to its exceptionally wide maximum aperture for portraiture.
What is a 50mm 1.4 lens used for?
A wide range of things may be photographed with the 50mm focal length because to the lens’s wide aperture. Because of its huge maximum aperture of f/1.4, it is an excellent lens for photographing in low-light environments.
