Never used canon dslr, it is not enough only looking the handbook. I want to use it in body. There isn’t bestbuy in beijing, so I went to the canon experience store last week. When you come out of the northwest entrance of the Xidan station, walk to northwest, the store is near by the Juntai department store. On corner of a building, the 1st floor laying out the DC and DV. The dslr locates in 2nd floor. Telephoto lens with 1ds mark 3 and 1d mark 3 are on two tripods. Other dslrs are behind of the show window. Special men serve nearby. The id card is your guaranty for using the camera and lens. There is no memory card in the dslr, you can only check the photo you shot one by one. Next time I will take my card.
I used the 5D mark Ⅱ with 70-200/4 100-400 85L, the 70-200/4 is very portable, large difference with 100-400 and 70-200/2.8. It is no wonder many people choose 70-200/4 instead of 70-200/2.8. After a few minutes, I am familiar with the body of 5d, it is very nice for using.
- The C1~C3 mode is very convenience which can saves your different configuration. For example, C1 is set for portrait, F/2.0, portait picture style, Spot Metering. C2 is set for landscape, F/11, landscape picture style, matrix metering.
- The upper limit of auto ISO is ISO 3200 which cant be changed, I did not know how canon decide the lowest shutter speed, I did not notice this when using zoom lens, but when I using 85L, the lowest shutter speed is 1/80s, if you shot the darker, the ISO ascend. All lens is unified or being set of the reciprocal of the focus length?
- The area of spot metering is too large, when the person you shoot is far, the area is already larger than the person’s face.
以前没有摸过佳能的机器，对佳能单反的一些设定光看说明书是不行的，想实际用下，北京没有百思买，于是上周末去了北京的佳能体验店，西单地铁西北口出了接着西北走，在君太百货西面，在个角上，两层，一层是便携数码相机和摄像机，单反在二楼。两个三脚架的大炮后面分别是大马三和小马三，其它机身都在玻璃窗里，有专门的工作人员看管，需要用身份证抵押，然后就可以任意组合镜头和机身了，不过机身里都没有存储卡，只能拍完一张看一张。太失算了，自己帯张就好了。
先后试用了无敌兔加xxb、db、85L，xxb非常轻便，和db差异明显，难怪很多都用xxb顶替xb。用用也就对佳能机身熟悉了，与nikon的机身差异挺大，但是也很好用。
- 指令拨盘里的C1~C3用户自定义模型非常方便，可以把你常用的设定保存，比如C1设为拍人物特写，光圈F/2，照片样式为人像，点测光。C2设为风景，光圈F/11，样式为风景，矩阵测光。
- 自动ISO的上限为ISO3200，快门速度不知如何定的，开始用变焦时没注意，不过用85L时发现最低为1/80s，再暗就会自动提高ISO。是所有镜头按1/80还是自动取焦距的倒数呢？
- 点测面积太大，离人远时，点测面积已经比人脸大了。
