Canon 1D Mark IV for digital camera reviews
  2010 is a veritable “Competition Year” has attracted worldwide attention in South Africa World Cup and the Winter Olympics are held every four years in Vancouver, Canada’s top events worldwide. Arena, players fight in a technical, physical, and the sidelines sports journalists have to fight is in the hands of photographic equipment and the level of great impact in sports photography I must take this opportunity to Canon 1D series has released a new flagship – EOS -1D Mark IV! It can be said that this is a platform for the stadium while the students SLR cameras.
  Improved 45-point AF system, a significant leap to 16.1 million effective pixels and up to ISO102400 the number of all the horrors of sensitivity to “pony 4″ – 1D Mark IV has been compared to a substantial and complete before the upgrade. At the same time, it also inherits the Canon 1D, 1Ds series cameras, “Three years is not to upgrade, upgrade in three years,” the fine tradition.
  Canon 1D Mark IV with a newly designed 27.9 × 18.6mm, APS-H-frame CMOS sensor, with 16.1 million effective pixels, a full 1D Mark III higher than 60%. At the same time, and before the 1D Mark IV have the same full-pixel 10fps continuous shooting capability, in order to achieve this functionality, Canon followed suit before the release of “Qi Di”, using two DIGIC IV processor, parallel processing.
Canon 1D Mark III is the first real-time shooting SLR cameras, as an upgrade product, 1D Mark IV full inherits this functionality and features of the popular features 1080p high-definition camera. You can say “pony four” all the characteristics of so many people are very concerned about, but in the tests before the start we were talking about the appearance from the camera.
    Canon 1D Mark IV camera with a common handle the top 135 integrated body design, which make the already full 1D masculine look more arrogant! Because the design so as to provide professional users smoothly, the Canon 1D Mark IV Although the core components of the comprehensive “new blood”, but the camera, and no significant change in appearance.
   Canon 1D Mark IV on the back there are many different functions of the buttons, but thanks to integrated design of the handle, so even if such a body behind it still have a plenty of room. In addition to the camera used in 3.0-inch, 92 million pixel LCD screen, the Canon 1D Mark IV in the shoulder, as well as the main screen can also find the following two auxiliary LCD. Compared to many cameras, open the left shoulder, Canon 1D Mark IV placed in the above three function keys to alleviate the situation of the right shoulder button too dense.
    I believe many people for the camera batteries, camera batteries, especially the low-end general complain, everyday applications, so that we often can not be readily patiently by shooting. The Canon 1D Mark IV because of the professional position, so in batteries used to make a lot of people envy 2300mAh, 11.1V high-voltage lithium batteries. Large capacity to ensure the camera share in the endurance capacity of 300-2000 Zhang’s shooting ability (according to different shooting modes, usage may be), while the voltage was 11.1V camera Ultra High Speed and Dual DIGIC 4 processor provides the the most powerful of the “logistical support.”
    Canon 1D Mark IV uses a 1D, 1Ds series cameras commonly found in pairs of memory card slots, but with some top-level design of the camera pairs of CF is different from Canon 1D Mark IV uses a CF + SD / SDHC combination.
    The new Canon 1D Mark IV new flagship Canon AF system can be described as the biggest bright spot, also made a lot of the industry and camera enthusiasts shines. Next, I resolved 1D Mark IV for everyone focusing module.
   Canon 1D Mark IV equipped with a new R & D 45-point TTL auxiliary video coincidence + phase detection AF system. In 45 pairs of focus included 39 “+” cross right focus and the focus of the six auxiliary. The previous generation of its flagship 1D Mark III’s 19 cross-automatic focus, plus 26 ancillary systems like automatic focus is now on the Canon 7D seen. Therefore, in theory, 1D Mark IV in the focus accuracy and sensitivity of the focus should be much better than before the. While the standard top-level cameras, in the focus area coverage on the 1D Mark IV is still not wide enough, but in the right focus right focus on the distribution and quantity, 1D Mark IV progress very large. In the Canon 1D Mark IV body, Canon achieved the automatic focus switching technology – if they had the camera when shooting fast-switching, the focus also will be moving to the previous position. While improved a lot, but we still need to test the practical effect of shooting, followed by the author through a group of photos to test the camera focus and continuous shooting ability.
   As stated at the beginning, the Canon 1D Mark IV and the World Cup, as well as the emergence of the Winter Olympics has a direct relationship between the two top-level events. To dominate the field of sports photography is the Canon 1D Mark IV’s mission is also a Canon dream thing. Evaluation data from the point of view, 1D Mark IV in terms of focus, imaging level, or pixel areas have been equipped with this level. And in the 1D Mark IV, Canon reached the perfect product for their own generation than the full 1D Mark III.
   However, to the evaluation at the end, I still wish to raise Canon 1D Mark IV’s competitors – is also listed on the recently released Nikon D3s, the game between the two can be regarded as a struggle between destiny. Similar circumstances in terms of price, both in the consolidated performance can be described as very close, Canon 1D Mark IV have obvious advantages in the pixel, and with the lens factor of 1.3 can be a better ability to play telephoto lenses. And the latter with full-frame, low-pixel sensor is undoubtedly superior noise control. In focusing on, 1D Mark IV significantly improved through the catch-up Nikon’s Muti-CAM 3500 AF module, and in effect open the servo-focus shooting, battery life time and shutter lag, the two are very close … …

The face of powerful competitors, slightly senile, and budding of the 1D Mark III’s “Qi Di” is obviously not a suitable candidate for the Canon 1D Mark IV Reloaded 2010 Canon White is the most powerful gun array candidates. Pitch at the World Cup in South Africa, in Canada, slightly Piaoman snow mountains on both sides of the base, I believe that Canon 1D Mark IV will become a white red circle behind the lens of the commanding general of the most exciting!
