Novice photographers and those who plan to buy a SLR camera for the first time, most often study information about which camera to choose. In addition, they can find information on lenses.
After all, there are two types of them: “zoom” and “fix”. This article is completely devoted to “fixes”. Here, each reader will find answers to the following questions:
- What is a “fix” and how is it different from a “zoom”?
- Which lens is better - "zoom" or "fix"?
- Advantages of the “fix” and disadvantages.
- The division of lenses depending on the purpose of shooting.
Let each of the novice photographers make the right choice. Therefore, it is recommended to read the article to the end.
What is a “fix”
What is a "fix"? To begin with, it is worth mentioning that there are two types of lenses: “zoom” and “fix”. The first makes it possible to zoom in or out of the subject so that it is not necessary to step back a few steps or, conversely, get closer. That is, the photographer has the opportunity to change the focal length on the lens itself using the built-in ring. Thus, without changing its location, it increases or decreases the subject.
On the contrary, the "fix" does not make it possible to zoom in or out. To cover the entire frame or enlarge the subject, you need to move from place to place until you find the ideal position.
How to distinguish these lenses in order to choose the right one? “Zooms” are labeled so that the consumer is aware of the minimum and maximum focal length (FR) of the model. For example, FR = 18−55 mm. This means that it is possible to zoom in or out on the subject a few meters, but not more than 10-15.
"Fix" is marked with only one value, for example, 50 mm. That is, the focal length cannot be changed. There is also no adjustment ring on the lens barrel. There is only an autofocus ring. Thus, it is easy to distinguish two types of lenses by marking only.
Which lens to choose - “zoom” or “fix”?
But this is perhaps the most crucial moment. First of all, you need to ask yourself if you are ready to change your location if necessary. One can imagine that a photographer is standing on the seashore. Three hundred meters from land a catamaran swims. I want to capture it, but I can’t, because it is impossible to zoom in on the picture, remaining in place.
The following is an example of the impossibility of estrangement. For example, apartment owners want to put up their living space for sale. In the ad you need to add good pictures to characterize the entire apartment. But the “fix” does not allow you to photograph a cramped kitchen so that as much space as possible gets into the frame. On the camera screen or on the finished photograph, only certain places in the catering unit are visible. And at this moment it becomes clear what the "fix" is for.
On the other hand, experienced photographers, if possible, acquire the entire arsenal of “fixes,” that is, with different focal lengths. So, if a person has the means and has the ability to carry all interchangeable models with him, then it is possible to dwell on “fixes”.
Advantages and disadvantages
It was discussed above what a “fix” is in the camera, as well as examples of what can lead to disappointment from an unsuccessful purchase. The inability to adjust the focal length is the only drawback in this case.
But there are many advantages. It’s worth starting with aperture. Many professionals prefer "fixes" because of the high aperture. That is, the photographer has the opportunity to shoot in a darkened environment without damage to the image.
Also, the advantages include the quality of photography, which in many ways surpasses the "zoom". Firstly, there are no noise in the photo. Secondly, background blur and the subject itself are perfect. It turns out a beautiful artistic composition. In addition, color rendering is much better. Therefore, if the reader wants to know what a fixed lens is, and then buy it, then he is on the right track.
Which lenses fit
Depending on the RF, you need to choose lenses for:
- spherical shooting ("fisheye") - 8 mm;
- landscape - 24 mm;
- portrait or still life - 50 mm;
- macro photography - from 60 to 100 mm.
Now it’s clear how to find the right model and what is a “fixed” lens. For Canon, Nikon and other photographic companies you can choose the right one. But before buying, you should make a test shoot.
Finally, it is worth adding that only by practical means can we understand which particular lens is suitable for a particular purpose.
