把骗子引来了

支持；我在上海国庆前入的C家佳能EOS 5D MarkII，佳能EF 16-35mm f/2.8L II USM，佳能EF 50mm f/1.2L USM，佳能EF 70-200mm f/2.8L IS USM(小白IS)；

转换肯定会有差异，但不会太大，甚至无法察觉，好就好在无论多少fps，5D2都是逐行。

说实话最好的电脑帧频是30fps，那5D2就别升级了。退一步应该是25P，再怎么说整数也比浮点好，要是电脑是CRT 75Hz也合适。

所以升级就拍25，也符合咱们国家制式；不升级就拍30.

哈哈， 爽YY。

不知道在电脑上播放的话，不同帧率的清晰度有没有不同？
我肯定没机会拍东西去放电影或者电视，，只是在电脑上看的话， 应该选哪个？
谢谢

学习了。5DII拍照片，只用了相机一半的功能，以后也试试拍视频。^_^

24=23.976 这是全球标准电影格式，如果是在中国拍数字电影，也要求必须用24P。

25P/50i PAL中德英等电视制式，在大陆购买的行货民品摄像机，都只具备这个，这样用5D2拍的广告 宣传片 专题片可以直接在电视台播出，以后我等就都拍25P啦！

29.97 NTSC美日电视制式，有一点可惜是升级完5D2，30P就变成29.97了，我还是挺喜欢30P的，因为一般液晶都是60Hz，能想想吧？

棒透了！！！
这个是对专业video从业人员的大喜讯，对摄影没啥意义的，呵呵

很好很期待。

好的

Canon adds 24 and 25fps HD Movie recording
to the EOS 5D Mark II with Firmware 2.0.3
London, 2nd March 2010 – Canon today pre-announces the release of a firmware update for the multiple award-winning EOS 5D Mark II. Originally announced in late 2009, the update adds 24* and 25 frames per second (fps) recording to the camera’s EOS MOVIE video function, and will be available as a free download from the middle of March.

Developed following feedback from photographers and cinematographers, Firmware 2.0.3 further enhances the EOS 5D Mark II’s excellent video performance. The addition of new frame rates expands the camera’s video potential, providing filmmakers with the ability to shoot 1080p Full HD footage at 24fps (actual 23.976fps) – the optimum frame rate for cinematic video. 25fps support at both 1920x1080 and 640x480 resolutions will allow users to film at the frame rate required for the PAL broadcast standard, while the new firmware will also change the 30fps option to the NTSC video standard of 29.97fps.

A new histogram display for shooting movies in manual exposure, shutter-priority (Tv) and aperture-priority (Av) have been added, and exposure modes will also be available in movie mode. Improved audio functionality will allow users to set sound record levels manually using a sound-level meter displayed on the LCD screen. The audio sampling frequency has also been increased from 44.1KHz to 48KHz, providing the optimum audio signal typically required for professional or broadcast material.

With its full frame CMOS sensor and compatibility with Canon’s wide range of premium lenses, the EOS 5D Mark II is already recognised for its outstanding HD video performance. Launched in September 2008, the camera immediately created a wide range of new possibilities for photographers and videographers, and the addition of new frame rates and manual audio levels extends those possibilities even further – allowing movie makers to shoot stunning movies to suit practically any creative purpose.

Extreme sports photographer Richard Walch was one of the first to be given the chance to use the newly updated EOS 5D Mark II to shoot the snowboarding movie “I Love My Friends”. Commenting on the EOS 5D Mark II’s video performance, Richard said: “The addition of the new frame rates opens up a whole new range of possibilities. If you’re a cinematographer, independent film maker or just enthusiastic about making your own movies, get out there and give it a try”.

“I Love My Friends” shot by Richard Walch on the EOS 5D Mark II with the new firmware includes a look behind the scenes video is available to view at http://www.canon-europe.com/eos5dmarkII.

The firmware will be available to download from mid-March from the Canon website http://www.canon.com/eos-d/

*Actual frame rate: 23.976fps

看来这次，Canon想把5DII推向专业摄像领域。5DII的价格……^_^

24、25和29.97fps帧率

谁给讲一下，这几个帧率有什么区别，如何选择设置？
