数码相机没有光学变焦和自动对焦？英文双语对照

一、数码相机没有光学变焦和自动对焦？

这个问题本身就有点问题。

其实任何照相机本身没有光学变焦能力，光学变焦的实现是取决于他所配的镜头。

卡片机说它有光学变焦是因为镜头不可拆下（硬要拆就坏了），是连为一体的，所以说某某相机有多少倍光学变焦。单反机一般镜头是可拆换的，甚至机身和镜头是分开买的，所以单反机（指机身）是没有光学变焦的。

二、数码相机的自动对焦功能怎样开启？

不需要，对焦区域选择是自动对焦的选项，可以告诉相机自己对于对焦区域的偏好，或者手动在屏幕上选择对焦点等。而手动对焦的意思是需要自己手拧对焦环进行对焦。

三、奥林巴斯数码相机如何进行对焦？

这样的情况是在许多的被拍摄物光线不好的时候，或者没有线条明显对焦点的时候，不容易对焦若是除去以上的情况都无法对焦的话。那么只能去进维修站了。

四、数码相机怎么对焦？

有两种对焦方式 ：

一是在自动对焦状态下半按快门进行自动对焦，这种情况下只需要对准被摄物体，半按快门，相机就会自动对焦，对焦完毕后完全按下快门拍摄；

二是手动对焦状态下转动镜头对焦环进行手动对焦。这种情况下，将佳能的镜头上手动对焦开关拨向MF，就是手动对焦状态（处于AF就是自动了）。这时如果要对焦，可手工转动镜头上的对焦环（不是变焦环，对焦环一般靠近镜头外沿），同时眼睛往取景窗中观察，景物清晰时，就对焦准确了。

五、自动对焦锁定后如何改为手动对焦？

自动对焦锁定后改为手动对焦应该这样操作：将相机上或镜头上的AF切换到MF，即可改为手动对焦模式。这样操作的好处就是一次对焦后可以在拍摄距离不变的情况下拍摄多张照片无需反复对焦。

六、极米如何自动对焦？

1、极米H3投影仪遥控器底部设计有变焦杆，变焦杆滑动到Focus对焦一端，极米投影仪会进行自动对焦；

2、极米何投影仪遥控器底部的变焦杆滑动到Focus一端时，按下遥控器的音量加减键可以进行手动对焦；

3、通过系统设置也可以进行一键自动对焦，打开极米投影仪的系统设置，进入最底部的更多设置，选择对焦校正中的一键对焦即可开始一键对焦。

七、佳能700如何自动对焦？

镜头上有个开关，一边是“AF”，一边是“MF”的，把开关拔到“AF”一边就是自动对焦。把开关拔到“MF”一边就时手动对讲，可以根据需求自行进行调整。

对焦是指使用照相机时调整好焦点距离，英文学名为Focus，通常数码相机有多种对焦方式，分别是自动对焦、手动对焦和多重对焦方式。对焦也叫对光、聚焦。通过照相机对焦机构变动物距和相距的位置，使被拍物成像清晰的过程就是对焦。

八、数码相机拍照对焦变暗？

原因：

相机完成对焦的过程中也要完成测光，通过测光的结果调整光圈快门甚至感光度，如果取景框中的光线分布不均匀，反差比较大，对焦点的变化会引起相机处于不同的模式，比如从风景模式到微距模式，这个模式是自动的对用户不可见，模式的变化就会引起相机参数的变化，给用户的感觉就是液晶屏取景器中的亮度发生变化。

如果感觉这个画面过暗，可以重新选择对焦点，比如选择比较暗一点的地方重新对焦，相机重新测光和计算，这样就会提高画面亮度。：

九、佳能600D数码相机如何手动对焦？

手动对焦的步骤：

步骤1：按下实时显示拍摄按钮

　　将相机固定在三脚架上，按下相机背面的实时显示拍摄按钮，启动实时显示拍摄功能。

步骤2：将开关切换至手动对焦

　　切换镜头的自动对焦模式开关，选择手动模式。

步骤3：调节可旋转液晶监视器的角度

　　将可旋转液晶监视器调节到更易观察的角度。

步骤4：移动对焦点位置

　　使用多功能控制钮将对焦点移动至希望合焦的位置。

步骤5：使用放大按钮放大显示

　　按下放大按钮，可依次显示5倍和10倍的放大图像。

步骤6：手动对焦

　　一边观察放大影像一边转动对焦环，直到影像显示最锐利为止。对焦最锐的点容易因对焦环的轻微旋转而丢失，因此需要注意。

步骤7：按下快门按钮

　　返回全画面显示，确认图像整体情况，然后按下快门按钮。

十、普通的数码相机录像时候能不能自动对焦？

现在的普通相机都可以实现录像时自动追焦，只要把对焦方式调为AF-C就是连续自动对焦方式就可以实现这个功能。另，为防止录像画面过度抖动，录像时最好不要有太大动作。
