When it comes to the choice of lens, it can also be said to be a big door. After all, a lens will also have a great influence on photography creation. Today we happen to talk about those things about the lens.
Are zoom lenses always inferior to fixed focus lenses?
There is an old saying in the photography circle that zoom is not as good as fixed focus. Many photographers also believe that the cheapest prime lens is better than all zoom lenses. Is that true? Many times people will focus on the lens aperture. Fixed focus lenses can easily increase the aperture. However, due to the limitation of factors such as size, the aperture of the zoom lens may not be particularly large. But if you put aside the aperture, such as some shooting subjects that are sufficient when using f/2.8, will the quality of the zoom lens be inferior to the fixed focus lens? We also made a special experiment.
Canon EF24- Comparison of 105mmf/4LISUSM lens and EF35mmf/1.4LUSM lens
The above picture is EF35mmf/1.4LUSM, and the picture below is EF24-105mmf/4LUSM. After zooming in to 100%, I believe everyone can see The difference in sharpness, right? In fact, the quality of a lens like the EF50mmf/1.8 that we call a “small spittoon” is indeed not bad, as shown in the figure below, even compared to the EF24-105mmf/4LUSM, it is slightly better.
EF50mmf/1.8 Compared with EF24-105mmf/4LISUSM
, you know, the price difference between these two lenses has reached 6-7 times, but the picture quality is good but not the expensive one, so it seems that everyone always says It seems reasonable that fixed focus is better than zoom.
Canon EF24- 70mmf/2.8LIIUSM lens
In fact, this is not the case. When the lens rises to a certain level, this kind of thing will no longer happen, such as the highest level zoom lens of each company-the “big three yuan”. The Big Three are three zoom lenses that cover the three focal lengths of wide-angle, medium-focus, and telephoto, and the maximum aperture is constant at F2.8. For example, the Canon EF24-70mmf/2.8LIIUSM lens, which can be called the king of mirrors, has excellent quality. It has the same or better quality as the fixed focus lens at each focal length. Let’s compare the “small spittoon” with this lens. It is not difficult to find that the image quality of the EF24-70mmf/2.8LIIUSM lens clearly surpasses the “small spittoon”.
EF50mmf/1.8 Contrast with EF24-70mmf/2.8LIIUSM
In fact, EF24-70mmf/2.8LIIUSM is not inferior to Canon’s L-grade red circle fixed focus lens in terms of image quality. I also used this lens to compare with Canon’s other civilian humanities lens EF40mmf/2.8STM with very good image quality before, and found that the Canon EF24-70mmf/2.8LIIUSM at 40mm end compared with EF40mmf/2.8STM. The same quality. In fact, the “big three yuan” zoom lens is quite good in terms of image quality, especially the “big three yuan” lens on the RF mount micro-single that Canon later launched. Next we Let’s talk about how to use the “big three-dimensional” zoom lens with different focal lengths.
Wide-angle zoom lens with a wide range of uses
The focal length of the common wide-angle zoom lens is generally 14-24mm. , 16-35mm, 17-40mm and 15-35mm, etc., and the large three-dimensional wide-angle zoom lens is obviously the best choice for landscape photography. First of all, the wide-angle lens can get a better view of the scenery-such as this Tiananmen photo , This photo was taken with a 30mm focal length, and you can see that Tiananmen Square and the national flag are included.
And in this photo, everyone must think that I was shooting in an unmanned scene. In fact, everyone knows that Tiananmen Square has many tourists most of the time. In fact, this photo is different from before. ‘S photos were taken at the same location, but with a wider focal length, which can be more shocking with a wide angle.
Then someone will ask at this time, is it not easy to use wide-angle fixed focus? Let’s take a look at this picture and think about it, in this environment. Is zooming or fixed focus easy to use?
In fact, Camera position is not a good choice in landscape shooting, so the angle of view change brought by the zoom lens is very important. For starry sky shooting, the maximum aperture of F2.8 is sufficient for shooting. Many star trail photos are taken with F4 lens models. In fact, as long as you don’t take the Milky Way, you basically don’t need a high sensitivity, and the F2.8 aperture is enough.
And many wide-angle zoom lenses also cover 35mm, and can also shoot some humanistic sketches and still life subjects , It also expands the use scene of the lens.
You will find that the photo just now was not taken with a large aperture, because the humanity type of photo requires the participation of the environment, even if it is a person Environmental portrait, so generally do not need a particularly large aperture, in order to reflect the environment, so the large three yuan F2.8 aperture is very sufficient.
Have you noticed at this time, if it’s just shooting in the travel picture In terms of scenery and customs, can it be done by a wide-angle big three yuan, such as Canon RF15-35mmF2.8LISUSM? So the wide-angle “big three yuan” lens is really used very much.

Is the middle focal length zoom lens really tasteless?
Many people think that the mid-focus range is neither wide nor far, so it is better to use fixed focus and large aperture to shoot people. At first glance, this theory seems reasonable, but in fact every lens has its most suitable subject matter. The purpose of choosing the right equipment is to improve efficiency, so naturally there are subjects that are most suitable for medium focal length zoom lenses, such as my favorite ancient Building scenery.
Canon RF24- 70mmF2.8LISUSM
When shooting Taimiao and Forbidden City, the distance between these buildings and you is neither far nor too close. Ultra-wide angle can not capture details, and telephoto does not have the atmosphere of large scenes, so it is most suitable This is the middle focal length, which is why the Canon EF24-105mmf/4LISUSM is the most popular choice for Master Li Shaobai to shoot the Forbidden City. Let me show you a few of my photos. One lens can shoot both part and panorama very well. I used Canon’s RF24-70mmF2.8LISUSM.
In fact, even in portrait shooting, mid-focus zoom lenses are used in many shooting scenes, such as Flash photography, because the aperture will have a greater impact on exposure in flash photography, so the aperture is often not very large when using the flash. For example, this photo was taken with a small aperture to darken the natural light, and then use the flash to fill in the light. . Therefore, the middle focal length zoom lens is of course a fish in water when used in suitable subjects.
Everyone has to have a 70-200
70-200mmF2.8 lens is used as a telephoto big three yuan, the most common application is telephoto, such as shooting birds, or shooting competitions, these are the work of standard telephoto lens, Canon RF70- Although the farthest focal length of 200mmF2.8LISUSM lens is only 200mm, Canon’s RF lens has high resolution, and the EOSR mirror with high image quality also has enough cutting space, so many telephoto content can be easily Get it done.
Here is a simple tip that many students shoot sports Vehicles always fail to capture the sense of speed because you have fallen into a misunderstanding, and you think fast-moving objects should be shot with high-speed shutters. In fact, this is not the case. For example, this motorcycle was shot with a 1/80s shutter, and the focal length is 200mm. It seems to have a sense of speed, right? According to the situation at the scene, use a slower shutter and focus on the center area. This effect will be achieved by shaking the machine on the monopod to follow the focus. After you learn this trick, you can go back and try it on the road. La.
In addition, the Canon RF70-200mmF2.8LISUSM lens There are also many applications in portrait shooting. The 70-200 focal length lens itself is known as a beautiful head, which is very suitable for portrait shooting. You can take advantage of the compressed background characteristics of the lens to shoot. For example, this photo:
We can see that the background trees are very sparse, but we can use the feature of telephoto background compression to make the trees in the background look dense At the same time, the focal length of 70-200 can also shorten the distance between the background and the characters, such as this photo.
The shrubs and plants behind are far away from the characters, if you use a wide angle The background of this work may not be ideal when shooting at some focal lengths, but with a telephoto lens, the distance between the subject and the background is narrowed, and the environment is shown: withered grass and low shrubs in the distance.
So you see, the 70-200mm lens can also be described as a generalist. It can cover multiple subjects including portraits. It is indeed worth having.
Editor’s point of view
Let’s review the content of this article. First of all, is zoom really not as good as fixed focus? In fact, this is not the case, like Canon’s L-class red circle large three-dimensional zoom lens, it has or even exceeds the performance of the fixed focus lens. Secondly, the wide-angle zoom lens can not only bring a wide-angle impact angle of view, but also the design of the zoom can make it suitable for different shooting scenes, convenient for composition, and the large aperture of the “big three yuan” lens F2.8 is also sufficient for most shooting Demand; the zoom lens at the middle and telephoto end is not the so-called chicken ribs. We choose the lens not only to focus on the parameters, but also to find the suitable shooting themes for this lens, such as the compression effect of large aperture and medium telephoto in portrait shooting. It has very good results-for example, the Canon RF70-200mmF2.8 “big three yuan” lens we mentioned last, I believe it will be a must-have lens for many users.
