Camera lenses are among the priority equipment for those who are investing in visual productions, be it photography or. They are almost like a magical element: they manage to record details in an image that the human eye is often unable to capture.
This article is dedicated to them! You will know some of the main technical elements — such as the focal length and the aperture of the diaphragm — in addition to knowing the main types of lenses and their particularities. Read on and find out!
The importance of glasses
Choosing camera lenses is one of the most difficult (and at the same time, most enjoyable) tasks in the life of a professional photographer.
They are responsible for effects in captures that are responsible for differences in images — they can distort edges, bring objects closer together, produce detailed focus, etc.
The investment depends a lot on your objective. Therefore, it is important to have basic notions of the main models and their differentials.
In addition, some technical elements manage to completely transform the result of the material. Knowing those aspects can have a great influence on your content.
Elements to consider when choosing the lens
If you don’t understand the subject, you’re probably not very familiar with the technical terms of camera lenses. That’s normal, in the end, it’s about professional knowledge.
The main ones are:
- Aperture of the diaphragm: it has to do with it. The lower the number indicated in the lens specifications, the greater the light input (always the reverse!). For example, an f/2.8 has a larger aperture than an f/8;
- Focal length: it is one of the characteristics related to sharpness. Longer focal lengths (expressed in mm) provide recordings at greater distances, but with a more restricted field of view;
- Image Stabilizer (IS): this resource reduces or eliminates trepidation at the time of filming or capture;
- Type: Camera lenses are also categorized according to their specific use, as you’ll see later.
The types of lenses
You are already beginning to understand more easily the operation of and photography, right?
So, are we going to know the main models? We made a brief description with the particularities of each one. Look.
Prime lenses (fixed focal length)
Prime lenses do not have zoom, therefore, they have less distortion and more quality in the captures. The opening in this model is usually higher, reaching f / 2.8. They are very versatile for photography and recording. By unleashing creativity, these lenses produce great results, even if they’re not specialized.
Zoom Lenses
Zoom lenses have image distortion very close to that of the human eye. They are versatile like the prime ones, but they have the resource of approaching the focus, ideal for when it is not possible to get as close to the central content of the capture. So they are useful for a variety of purposes, from landscapes and animals to portraits.
Wide Angle Lenses
However, of the specialized ones, the wide-angle lens is preferred for small environments, such as. Their models vary from 28mm to 50mm and manage to record a good viewing angle. The big difference is that they slightly distort the edges, which makes objects appear a bit more distant.
Fisheye Lenses
For those who like more artistic results, the Fish Eye is quite sought after. The center of the lens is slightly “jumped”, creating a distortion at the edges, so that the final effect is rounded at the margins. It manages to record images in a radius of 180 degrees.
macro lenses
One of the favorites of professionals and among the most famous camera lenses is the macro, a specialist in close-ups. With a fixed focal length, small details — such as insects, textures or tiny flowers — are recorded with great sharpness. Thus, the images are incredible without the need for.
telephoto lens
Unlike the macro, especially for close content, the telephoto lens is ideal for capturing objects that are far from the professional. The focal length is long and therefore the angle of view is much smaller, but the lens produces excellent results in quality and sharpness.,
Super telephoto lens
Going a little further, the super telephoto lens has the same purpose as the previous one, but is capable of recording much more distant objects. With 200mm or more (some reach 1,200mm), the professional can make detailed captures of stars and wild animals, for example. Being heavy, it requires a tripod.
Tilt shift lens
Lastly, tilt-shift is a Canon brand exclusivity. It was designed to photograph or record architectural objects and its resources are capable of altering the perspectives of the image. In this way, the professional achieves effects of inclination and parallelism, for example.
Bonus Tip: Tutorial to Clean Your Camera Lens
Clever! You’re practically a lens specialist now.
Now, knowing all the names and technical elements is useless, but failing in a basic task: cleaning.
This equipment requires great care to avoid damage. Therefore, check out some suggestions.
Removes surface dirt
The first step in cleaning is to remove surface dirt, such as dust. To do so, use a brush with very soft bristles, which will work like a feather duster. The suggestion is to invest in a makeup brush.
Attention: never blow, because the drops of saliva can cause more stains on the lens of your camera.
Use suitable solutions
Eyeglass lens fluid, glass cleaner, isopropyl alcohol: These three products are recommended champions for cleaning camera lenses. But they are not ideal and can be detrimental to the surface of the equipment.
In order not to take risks, it is worth buying your own solutions for this purpose in specialized stores.
Invest in specific materials
The last suggestion concerns how to remove stains.
Always try to use soft flannels. Those suitable for cleaning glasses give off lint, which can greatly impair the performance of the lenses.
Again, the ideal is to buy special fabrics in specialized stores.
In all cases, remember to handle the camera lenses gently. They are very sensitive, regardless of type.
This equipment deserves care, at the end of the day, it provides a professional result to your videos.
To further improve your videos, how about also investing in cameras?
