- The first number gives the range of focal lengths in millimeters, while the second gives the lens speed (for the 1.4/50 designation it’s vice-versa).
- The first number or pair of numbers indicates the range of available focal lengths in millimeters.
- The lens speed is listed after the small “f” and the slash.
What do the numbers mean on a lens?
Focal length is expressed in mm and a higher number means a bigger zoom, while a lower number mean the lens can be used for wider shots. As a rough reference, the human eye is said to see about the equivalent of 30-50 mm on a full frame camera (more on that later).
What does 55mm lens mean?
A lens stamped 1.8 / 55 means that the focal length is a fixed 55mm. Prime lenses have only one focal length, while zoom lenses have a range of focal lengths. Smaller numbers are wide-angle lenses. The larger the number, the more zoomed in you can get. A reading of 18-55mm is a focal length range.
What is the meaning of 70 300mm lens?
The 70-300mm lens is a telephoto zoom lens made by Nikon. The lens has an F-mount to work with all the SLRs line of cameras (except the early 70-300G with the D40), although the more recent AF-P lenses will not focus on film SLRs or older DSLRs (roughly before 2013).
What does 50mm lens mean?
50 mm refers to the focal length of a lens. By itself, 50 mm means 50 millimeters, which is about 2 inches. In terms of photography, this measure is a general description of how much magnification a lens will have.
What does 1 2.8 mean on a lens?
The true meaning of the “1:2.8” text on a lens is actually to state that the lens is designed to have exactly 1mm of entrance pupil diameter for every 2.8 mm of focal length with the “entrance pupil” being the aperture diameter.
What does 1.4 mean on a lens?
The lower the f-stop number, the larger the aperture, the more light enters the camera. So, f/1.4 means the aperture is pretty much all the way open, and lots of light is entering the camera. You might be wondering why f-stops are displayed using decimals (e.g., 1.4, 2.8, and more).
What does 300mm lens mean?
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.
What is a 75 300mm lens used for?
Lightweight telephoto zoom
This 4x telephoto zoom lens is ideal for the budget-conscious photographer with an interest in shooting sports, wildlife or portraiture. In common with other telephoto lenses, the EF 75-300mm f/4-5.6 III compresses perspective and allows the photographer to restrict depth of field.
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.
How far can a 300mm lens shoot?
First Priority is Focal Length
| Focal Length | Distance (Crop frame) | Distance (Full frame) |
|---|---|---|
| 100mm | 19 yards | 12 yards |
| 200mm | 38 yards | 23.5 yards |
| 300mm | 56.5 yards | 38 yards |
| 400mm | 75.3 yards | 50 yards |
When would you use a 70 300 mm lens?
The 70-300mm is ideal for wildlife, nature, and sports photographers who’re looking for a budget zoom lens that can help improve their photography level. Since it is versatile, the Nikon 70-300mm functions well in different environments.
Which is a better lens 55 250 or 75 300?
The 55-250 IS is excellent value for money and a far superior buy than any 75-300 zoom. I have one and it compares quite well with far more expensive lenses. The 70-300 IS is potentially a better choice mainly for its longer reach but it costs much more and is bigger and heavier.
What does 600mm lens mean?
Taking your examples, the lens with a 600mm maximum focal-length has the smallest angle-of-view and therefore will magnify a distant object more. This type of lens is mostly used for bird and wildlife photography.
Is 18-55mm lens good enough?
A 18-55mm lens should really be only used at its widest angle, 18mm. This focal length is more than wide enough for most uses, including landscape photography. Unless you are always shooting landscapes, there really isn’t any reason to consider something else for the job.
What magnification is a 600mm lens?
With a 600mm lens, you can get a magnification of 12x in your subjects. Trust me that’s simple mathematics. With a 50mm lens, you get the same field of view as an eye, so 600/50, you’ll get 12, and it’s the times you can zoom into the subject.
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 size lens do I need?
If you want to fit more into your frame, you might want to look into wide-angle focal lengths: 14mm, 20mm, 24mm, 28mm, and 35mm. On the other hand, if you want to get as close as possible to your subject, go for a telephoto lens with focal lengths that usually range from 50 to 100mm.
What does the f1 8 mean on a lens?
Aperture sizes are measured by f-stops. A high f-stop like f/22 means that the aperture hole is very small, and a low f-stop like f/1.8 means that the aperture is wide open.
What do you use a 50mm lens for?
Why use a 50mm lens? No matter what type of photography you like, there’s a good chance you can use a 50mm lens. It’s one of the most popular lenses on the market, and it can be used for anything from portraits and car photography to landscapes and nighttime shots.
What is F4 in camera lens?
F4 is an f-stop. This is aperture or how open the lens is. It Affects the depth of field and the amount of light entering the lens/camera sensor. The wider the opening is, the more amount of light can enter resulting to brighter image.
