How Did I Become an F1 Driver?

How Did I Become an F1 Driver?

How did I become an F1 driver? Qin Miao discovered that he had the talent to become a top e-sports driver. Just during the college entrance examination period, he played with the simulator in his spare time and was surprised to find that he had the ability to compete with other professional e-sports drivers. You should know that he just played casually and had this ability. If he settled down to practice, Qin Miao would definitely have a bright future on the road of e-sports drivers. Qin Miao was ready to take the path of an e-sports driver if he failed the college entrance examination. But on a very ordinary day, Qin Miao gained a system. However, Qin Miao was still sensible. Even if he got the system, it was unlikely for him to become a formal F1 driver. Because when he got the system, he was already 19 years old and hadn't been exposed to anything related to racing before the age of 19. Two years later: Xiaozhou: There is no doubt that Qin Miao is a very talented driver, but I feel that racing is just a profession for him, his real hobby is live streaming and playing games. Lock: Qin? Just a second-generation Kimi. But then again, he plays CSGO really well, it was he who boosted my Earth. Old Man: Qin is a pure person, his life is only about racing... and video games. Dutch White-eyed Wolf: I have nothing to say about him. Bi Hai: If he spent half the time he uses to play games on the simulator, his achievements now would be far beyond this! Horner: I really appreciate Qin, he is a natural-born F1 driver and also a pure person, I very much hope he can join Red Bull and become one of us.

Does a DSLR camera have a lens blurring function?

DSLR cameras had a lens blurring function. It could be achieved in many ways, such as adjusting the aperture size. The larger the aperture (F4 and below are considered large apertures in the DSLR, such as F5, F8, etc.), the more blurred the background. Controlling the shooting distance, holding the lens closer to the subject, after focusing, the background would appear blurred. The closer the distance, the more blurred the background. Adjusting the focal length, the longer the focal length (55mm and above is a telephoto), the more blurred the background. You can also use Aperture priority mode (A) to choose the largest aperture to make the background blurred. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The camera lens is expensive

In the field of photography, expensive lenses had their value. Generally speaking, more expensive lenses had higher performance in terms of optical quality, workmanship, and performance. For example, in the field of medium and long focal length lenses, Canon's RF70 - 200mm f/2.8L IS USM was priced at 16999 yuan, and the Sony70 - 200mm F2.8GM OSS II was priced at 18999 yuan. These lenses were expensive, but they could provide better imaging results, excellent focusing performance, and good durability on their respective cameras. However, with the changes in the photography market, the relationship between price and value did not completely follow the traditional principle of "you get what you pay". In the micro-monocle era, although some high-end lenses had improvements such as quieter focusing, better design, and improved electronic functions, compared to similar lenses in the DSLR era, users felt less about the improvement in optical quality, but the price generally rose. Some of the affordable entry-level lenses, such as the 50mm f1.8 lens, were no longer as affordable as before. Branded lenses of this size were even hyped up to three times the release price. 24 - 105mm f4 or similar lenses were nearly twice as expensive in the micro-single era as in the single-lens reflex era. Although the optical quality had improved, there was no particularly huge breakthrough. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Pentax Third Princess DSLR lens

Pentax's Third Princess DSLR lenses referred to the FA 31mm F1.8AL Limited, FA 43mm F1.9 Limited, and FA 77mm F1.8 Limited. They were limited edition lenses, available in silver and black. They were small and exquisitely made. This statement was first put forward by the "Eye of the Wind" on the forum "Pentax135 lens godhood list---Joking about the P family's production lens group", and then widely spread in the Chinese world. In terms of optical performance, for example, the FA 43mm F1.9 Limited, as the earliest lens launched, was the "eldest princess" of the "three princesses." Its focal length met the definition of a standard lens, and the entire metal lens body was well-made. The image at the largest aperture was softer. After the aperture was reduced by two stops, the sharpness of the center and edge increased. The image was rich in layers, and the colors were fresh but not bright. It had a unique charm in portrait and landscape photography. The HD versions of these three lenses released by Ricoh (HD Pentax-FA 31mm F1.8 Limited, HD Pentax-FA 43mm F1.9 Limited, and HD Pentax-FA 77mm F1.8 Limited) adopted the HD multi-layer coating design, which could effectively suppress ghostly images or glare. The circular aperture design made the bokeh more gentle and natural. The surface of the lens was treated with SP anti-pollution coating, which made the anti-pollution characteristics better. In terms of price, the recommended price of the HD Pentax-FA 31mm was $1050, the recommended price of the HD Pentax-FA 43mm was $600, and the recommended price of the HD Pentax-FA 77mm was $800. The black version started with 0000001, and the silver version started with 1000001. However, in the era of digital single-lens reflex, due to Pentax's focus problems, these three lenses might run out of focus on the Pentax single-lens reflex body. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
