9 photographers’ critical demands

Modern digital photography technology has made rapid progress, and the new generation of digital cameras have more advanced functions, giving us a different photography experience. Even so, there is no camera that can meet the requirements of all people. It is understandable that photographers pursue something, but it seems that some requirements have risen to the level of nitpicking. Do you think the requirements of the following nine photographers are excessive?

1、 Buy a lens like an autopsy?

It’s strange that no matter whether you buy new or second-hand mirrors, everyone turns into a Virgo. They really care whether there is dust in the lens. They will inspect the lens very carefully. It seems that there is a grain of dust that will cause problems. Indeed, if you buy second-hand lenses, you should be careful, but what about new ones? You may not know that the lens cannot be “dust-free” from production to packaging. Do you want to be spotless? It’s more psychological, because there are many slight dust particles that you can’t see.

Of course, it is understandable that buying a new mirror requires dust-free, but the second-hand mirror also requires dust-free, isn’t it a bit hard to deal with yourself?

2、 Is it a whole picture or a pity?

“Full picture” is a myth. Some photographers are quite dedicated to pursuing full picture. I believe that there are some photography friends around you. Why on earth? Pursue picture quality? Pursue shallow depth of field? Then 135 full frames is definitely not your ultimate choice. Don’t forget, if your idea is that the bigger the better, we still have 120 frames that are much larger than 135!

In fact, selecting the right equipment is the most important, and we don’t need to focus only on the size of the picture. Now the gap between the residual and the full picture is getting smaller and smaller. It should not be an obstacle when we choose tools.

In terms of performance, the D500 is definitely higher than the D750, but the D750 is full frame! What should I do? Judging from the evaluation, the picture quality of the D500 of the residual machine is even better! Do you still believe that the bigger the bottom, the better.

3、 Why are pixels so low?

Similar to the pursuit of picture frames, some photographers will also focus on whether the camera’s pixels are high enough to pursue the number of pixels endlessly? Indeed, the higher the pixel, the more delicate the magnified image. But do you really need to study it bit by bit? If you usually only PO your works online and add compression algorithm, then even if there are 30 or 50 million pixels, it doesn’t mean much. What’s the use of 100 million pixels for you?

If you just look on the display screen, even if it is a 4K screen, 9MP is enough. There are many 12MP old cameras. 16MP cameras can be cut in half. 24MP is equal to three times the 4K pixels. Is it necessary to reach more than 24MP pixels?

What about the exhibition? 24MP image is enough for printing 24 × 36 inch (exhibition level!) or even larger photos. Besides, ordinary exhibitions only use standard photo frames. Only high-end commercial photographers will use ultra-high pixels, OK

4、 The lens should be sharp enough to make every part clearly visible?

Many novice photographers do not know the concept of “uneven image field”, so they often misunderstand or do not understand why the edge resolution of the image is always less than the central sharpness. They think that it is a problem with the lens, or that it is due to the poor optical quality of the lens. Then they think that it will be OK to change to a more advanced lens, but the problem remains.

In fact, as long as we understand the so-called “uneven image field” problem, we know that when light enters the photoreceptor, there is a difference between the entry angle and the distance. The larger the angle and the farther the distance are, the greater the difference will be. Therefore, we will see that the performance of the four sides of the image will be less than the central position. It is a bit “difficult” to make the whole picture equally sharp. However, one way is to shrink the aperture to increase the depth of field, which can bring the resolution performance of the four sides of the image closer to the center.

5、 No failure is allowed in the focusing sequence!

In recent years, digital SLR manufacturers often emphasize that the camera has strong capability of continuous shooting and focusing, and the subjects such as shooting sports and birds are first-rate. In fact, it is easy for users to misunderstand. In the continuous shooting of twenty or thirty pictures, several of them fail, and they think the camera is faulty. They question whether the camera is too old, and the focusing system is not up to date.

It should be understood that for most users, it is just a gimmick. The continuous shooting of digital SLR will basically meet the requirements. However, focusing may not be 100% accurate. The reason is that when focusing, the camera does not predict the position or focal length of the subject at the next moment, but depends on the results of prediction and calculation. Because it is only a prediction, there must be opportunities to make mistakes, which will lead to inaccurate focusing, especially in the face of speed It is more difficult to predict in calculation for the subject whose action changes greatly. Don’t expect this feature to hit every shot.

6、 WIFI, NFC and GPS must be available

The latest generation of digital cameras should almost all have WiFi/NFC wireless remote control or GPS functions. I feel that an advanced camera is qualified with these functions. Is that right? Although these additional functions will surely become the basic functions of the camera in the future, just like the previous Live View functions, are you sure these functions can be used? Is it worth giving up on a good camera because you don’t have one of these features?

7、 High ISO makes people worried

High ISO is the breakthrough point of camera manufacturers. It is a trap. Some photographers will pursue the image quality and want to slip through the milk. They extremely hate the noise of high ISO. In fact, does digital noise or film particles really not exist?

Sometimes, these coarse grains can also be a taste. Let’s take a look at the works of hall level photography masters such as David Hamilton or Senshan Avenue. Their rough performance has become their style. Who said that every photo must be as smooth as milk.

8、 Adding handles is professional

A lot of photography enthusiasts buy SLRs with battery handles, which is more professional than installation? Is there any such actual demand? We feel that most of them are unnecessary. The handle is mainly used for two purposes. One is to extend the shooting endurance, because two batteries can usually be put in, but do you really need to shoot for such a long time? Another purpose is to facilitate vertical shooting, such as portrait shooting. Some people think that it is more comfortable to shoot with the straightness handle. In fact, they have different opinions, because the camera will be significantly heavier after adding the straightness handle, and it will be very tired after a long time of use. If the time is short, does it make no difference?

As an aside, many film cameras also use similar handles, but the main function is to drive the motor, which can improve the continuous shooting speed of the camera.

9、 Aperture less than f/2.8 is too thin

Lens blindly pursues large aperture, which is also one of the classic myths in the digital photography era. In the era of film, we can say “yes” with great certainty. Especially when using a long focal length lens, because of the limitation of film sensitivity, it is more dependent on improving the safety shutter speed to maintain the stability of shooting. Therefore, a large aperture is necessary, and even without more ray assistance, this is almost the only way.

But what about the digital age? In fact, many people know that our dependence on large aperture lenses has been significantly reduced, because we have better high ISO performance, and the biggest role of large aperture lenses is to provide shallow depth of field effects. Are you really worth spending so much money to pursue a big aperture? Is it possible to make the lens smaller and easier to carry and use?
