How does Canon 7D record motorcycle races with high-performance autofocus and high-speed continuous shooting?

Canon 7D high-performance autofocus and high-speed continuous shooting record motorcycle races as follows: 1. Lens: EF 300mm f/2.8L ISUM/ manual exposure (F 1 1,1/60 seconds) /ISO 1000/. Although the tracking conditions of autofocus are very harsh, Canon 7D has successfully completed the tracking. 2. lens: EF 300mm f/2.8L IS USM/ manual exposure (F8, 1/500 seconds) /ISO 100/ white balance: with my favorite oblique sunset, I automatically took a high-angle photo. Canon 7D captures the subject well and obtains the desired position and composition of the velocity shadow. 3. lens: EF 300mm f/2.8L IS USM/ manual exposure (f 7. 1. 1/400 seconds) /ISO 200/ white balance: automatically capture the wonderful moment when the front wheel is held high and the rear wheel is balanced, which is full of motion. Because the subject accelerates at the back of the turn, the tracking of autofocus is quite difficult, but Canon 7D has easily completed the tracking. Sports photography is full of charm, and its high performance matches the high-speed continuous shooting performance of EOS- 1D series when shooting moving objects. The biggest attraction of the new autofocus system Canon 7D is that it is a high-end camera in EOS digital SLR series, second only to EOS- 1D series, and has the performance matching EOS- 1D Mark III. Hold the Canon 7D in your hand, and you will feel its excellent body design and exquisite workmanship. Although personal preferences are different, the configuration of keys and dials generally makes the operation very convenient. The solid magnesium alloy body can make people feel the calm texture of Canon 7D. Then, it is the CMOS image sensor of Canon 7D, with about 6.5438+0.8 million effective pixels. Although there is a high demand for 35mm Quan Huafu in the market, the equivalent focal length of 1.6 times is better for the close-up of sports photography. The imaging quality of about 6.5438+0.8 million effective pixels is also quite good. For example, this motorcycle shooting, the smooth leather texture of the driver's racing suit and the subtle bulge of the label are all presented in an unobstructed view through Canon 7D. Noise under high ISO sensitivity is well controlled, and you can use the sensitivity below ISO 3200 without any scruples. In addition to the above advantages, I have to sigh the high performance of Canon 7D's new autofocus system. The second generation of artificial intelligence servo autofocus greatly improved the defocusing phenomenon that was easy to appear in previous intermediate models. Continuous shooting performance as high as 8 frames/second can ensure that when shooting high-speed moving subjects such as sports photography, the subject can be tracked with high accuracy and the shutter opportunity can be seized at decisive moment. In addition, it can be set according to the preferences of the subject and photographer in the custom function. EOS- 1D series uses rich custom functions, which are almost reproduced in Canon 7D. Each combination shows different combination characteristics, which improves the sensitivity of artificial intelligence servo tracking by one level, while other items keep the default settings unchanged. The optical viewfinder with the field of view ratio of 100% is clear and bright, and the focusing peak is easy to confirm. Canon 7D has many bright spots, which can stimulate more creative enthusiasm of sports photography. The price of a camera with such excellent performance is moderate, which shows that Canon's efforts in Canon 7D are definitely worth having. Canon 7D's favorite local autofocus customization function can be customized according to the photographer's preferences and subjects. Canon 7D's custom function setting options are almost comparable to professional cameras. There are many custom functions related to autofocus, which is very gratifying for people engaged in sports photography. Among the various combination settings tried, the favorite is to only improve the sensitivity of artificial intelligence servo tracking by one level to shoot.
