如何得到相机的实际的焦距？
ErrorCode::ErrorCodeType CameraManager::getOpticalZoomFactorSync(PayloadIndexType index, float &factor, int timeout)
这个函数中也只返回了factor参数，factor参数如何跟实际焦距关联起来？

Agent comment from kyle.cai in Zendesk ticket #73563:

OSDK的变焦是在接口中获取到后算的。

那这里的lensInfo.data.min_focus_length 指的是变焦相机等效焦距还是实际焦距？

是这样理解嘛？ 实际的焦距 = factor * 最小的实际焦距
