, only the D200 and above body can be used to measure the light with these lenses. High-end wide-angle, Nikon's AF 28 MM F1.4D, nicknamed "Hundred changes to the demon", was also rated as the "seven weapons" in the camera Jasper knife. No market price. Header In addition to the AI-S head, the Nikon AF header has 800 blocks of aperture 1.8 and 2000 Multi-aperture 1.4. AF 50mm F1.8 D and AF 50mm 1.4D, 50 1.8 is also one of Nikon's value-added lenses. 50 1.4 colors are better than 50 1.8 colors. Th

transformation of Fourier transformation is easy to find, and its form is very similar to that of positive transformation; 3. the sine base function is the intrinsic function of the differential operation, so that the solution of the linear differential equation can be converted to the solution of the constant coefficient algebra equation. in a linear physical system, the frequency is a constant property. Therefore, the system's response to complex excitation can be obtained by combining its re

subject that uses computers to process externally obtained images. In France, graphics and images are a course.How to learn computer graphics? In addition to the basic knowledge of computer graphics, you also need the following knowledge. The more you know, the better you do.* You must learn English well. If you want to learn computer graphics, read English books and materials as much as possible.* Mathematics and computer graphics use a lot of mathematics. We can list some common ones:Advanced

my growth and are my solutions for training new employees. You can also try it. I have seen many posts about applying skills, but they are not practical. recipes do not mean that you can make good dishes. Whether you can make good dishes is still dependent on your ability to stir fry, stir fry, and stir fry every day. So what I want to emphasize here is that you cannot just look at any information you have collected, but you must organize, classify, and create a new structure by hand, this proc

these advertisements. Naming your things "ad" or "banner" is like writing "I am a free (female) female" on your face. There are definitely a lot of things to do with you. "Peony", "hibiscus", and "Qin Cao (" big inner security intelligence ")". You can choose one or more names. Short live the "button" tagWhen I first found the button tag, I was so happy. This tag is okay! It can contain many other labels to form different button styles (for example, you can write a button image like this ( Pict

Preface: Recently I have been studying Silverlight and WPF, And I am immersed in the sea of programming and design every day. I feel that optics does not have a sense of accomplishment when I do not practice. So I decided to write something here. After all, I haven't written an article for a long time. Hahaha. Now, let's get started with Silverlight and AI in the game ~~~ The focus of this lesson is to chase and Dodge. I believe all those who have pla

Meida applies the technology of producing G series lenses to the design and production of digital cameras, the product is called the GT lens.14. Zeiss shotZeiss. Zeiss is a German enterprise dedicated to Application Research and contributing to the development, manufacturing and sales of high-quality products such as optics, glass technology, precision technology, and electronics. Starting from 1846, carl Zeiss has already opened a workshop for produ

inclined surface. First, the bounce of an object is not a reflection in optics, therefore, it is not accurate to use "incident angle = reflection angle". Secondly, we need to consider the gravity/friction factors, which will affect the speed and direction. If you think about this complex problem with coordinate rotation, the solution becomes very simple. All vectors (also known as vectors in physics, although they are not exactly the same) can ap

; fourth, if optics are not used in practice, how can we put it together? Fifth, haha, is there another fifth? I don't know...In addition, to a large extent, I really think that university textbooks are not as good as textbooks in the middle school era. I think this is also normal. I use one set of Middle School Textbooks nationwide, how many generations have they been honed. college textbooks are used in almost one university, and printing errors are

may be a wrong inference. Second, His inference lies inNo prototype can be found in real life, and practices cannot be guided. Strictly speaking, I am not an idealist, Political CourseThe theoretical connection with practice at school has always been a guide for me to learn scientific and cultural knowledge (at least I think computer scienceAnd technology should be in this direction ). In fact, it is not enough for us to study mathematics, optics,

theoretical connection with practice in political courses has always been a guide for me to learn scientific and cultural knowledge (at least I think that computer science and technology should be conducted in this direction ).In fact, it is not enough for us to study mathematical optics and advanced mathematics in computer science (a typical Engineering College generally uses advanced mathematics ), we should take a look at mathematical analysis lik

protocols will be described in more detail in the "Network Connection Library" section later in this chapter.The underlying communication layer consists of network hardware and drive devices. This layer is usually independent from the network protocol layer, but there are still some correlations. For example, some devices only support a specific set of network communication protocols. There are many available network technologies, and new technologies are constantly being developed. The network

strict rule is useful because there is no need to worry about the number of combinations selected, and it will produce a small computing overhead. However, this technology cannot correct the wrong decision. Some methods have been proposed to improve the quality of hierarchical clustering.Representative algorithms include BIRCH algorithm, CURE algorithm, and CHAMELEON algorithm;Density AlgorithmDensity-based methods, a fundamental difference between density-based methods and other methods is tha

 Recently looking at a book called "Big Talk Data Mining", a simple summary summarizes some of the basic theoretical knowledge of data mining:1.Data Mining (also known in academia as Kdd:knowledge discovery in database) is extracted from a large number of incomplete, noisy, fuzzy, random data, which we do not know beforehand, The process of knowledge of potentially useful information. (most algorithms are based on the law of large numbers of statistics)What 2.Data Mining can do: Data mining ta

upper row of the green is brighter than the red and blue next to it, while the lower row of the pink is not adjacent to the yellow and light green eye. A great invention-The grayscale psychology formula was born! It brings together the essence of cutting-edge disciplines such as optical physics, eye-vision optics, human psychology, and art appreciation. It integrates science and technology, art, and social science, it is one of the most amazing scene

Fourier transform is widely used in physics, number theory, composite mathematics, signal processing, probability theory, statistics, cryptography, acoustics, optics, oceanic and structural dynamics., fourier transformation is typically used to break down signals into amplitude and frequency components ).Fourier transformation can represent a function that meets certain conditions as a linear combination of trigonometric functions (sine and/or Cosine

button. If you press the button for the first time, it is regarded as a press. When you click the button for the second time, it is determined as a pop-up, just do this. Personal suggestion: when you are a beginner, do not focus on such flashy things. The most important thing is to first master the relationship between the basic framework and classes of MFC. Otherwise, how does optics use several functions? It is not enough to know some interface des

Internet evolving in a variety of ways, but the popularity of smartphones has brought us many new tools and applications. This allows us to store and share knowledge anytime, anywhere. The use of synchronization technology allows us to see the same knowledge storage on Windows, Mac, Android, and iPhone. Recommended tools: Wiz Evernote 8. Share knowledge in storage, listen to and collect others' opinions and suggestions The storage of knowledge alone is far from enough, and we need t
