Sony photographer shutter adjusts brightness.

Now P-file has added a function called "program drift" (or flexible program), which allows users to choose different aperture and shutter combinations in a small range.

Generally speaking, the best combination of shutter and aperture will be used for P file first. So what is the best? Generally speaking, the aperture and shutter value of P file are the best and most reliable image quality.

For example, a telephoto lens, generally speaking, when the light is bright, you open the P file, and in many cases the aperture value will be automatically set at f6 to f8. This is because the camera is also intelligent. You should know that the definition of the general lens is the best when it is around f8.

For another example, if the light is slightly dim, when you turn the zoom ring of the lens, you will find that the aperture shutter value of P file will change accordingly (of course, this change has certain conditions). When you focus on 60.

P will "try" to set the shutter to 1/60, and when you set the focal length to 80, P's program will "try" to set the shutter to 1/80, which is safe and fast under this focal length.

Door, below this shutter, the camera may shake, resulting in blurred picture. From this example, P file seems to be very smart, knowing to ensure the picture quality first.

What's more, many of the current camera P files integrate the program drift function. Even in the P position, the aperture and shutter can be adjusted within a certain range. Therefore, you can think that P file is an automatic file with image quality as the main factor, taking into account aperture and shutter file.

So when is it appropriate to use P file? Of course, this question varies from person to person. However, in my opinion, the current P file, A file and S file are just like AF-A file, AF-S file and AF-C file in autofocus. Just like AF-A gear, P gear is a gear that gives priority to shooting quality, and the shutter and aperture priority can be switched within a certain range.

We know that it is very important to take a snapshot, and we don't have much time to think about the shutter and aperture. At this time, the P file is very valuable. So don't say that P file is useless. As Buddhists say, in the primary stage, mountains are mountains and water is water; In the intermediate stage, seeing mountains is not mountains, and seeing water is not water; In the advanced stage, see mountains or mountains, see water or water. In the same way, the first time you play SLR (single electricity)

People rely on P files because they don't need anything. And to a certain extent, with a theoretical basis, I always want to sharpen my knife and do a big job. It seems that it would be embarrassing and humiliating to put it in the P file, and then avoid the P file.

Stay away. In fact, if you get used to it, you will come back and rediscover the P file, because people's brain power is limited, and paying attention to one thing will ignore another.

Finally, I want to repeat that sentence, existence makes sense. Each gear has its advantages. When you use every gear well, you are not far from the master.
