100mm fact takes the effect
400mm fact takes the effect
Will read a group of print again:
2 pairs of anxious function get promotion
The author takes this to raised camera lens to undertake long fact is patted, because used pair of new anxious algorithm and processing chip, because pair of anxious speed of this whole and precision had promotion, the artillery that lets 400mm had the land of larger use force. To be opposite anxious and prevent tremble, the buy inside 100-40mm an independent double MPU miniature handles unit and DSP signal processor, cooperate USD motor to be able to undertake high speed data processing, raised response rate.
The author films sports match and animal, as a whole its right anxious it is very good, do not lose telephoto lens of more professional big aperture even.

The author had a test below dark luminous environment indoors designedly:
F6 1/50 second
F8 1/30 second
Below 300mm focal length, the photograph shutter rate that author fact takes all under its safety shutter, although the definition that shakes a system to still can raise a photograph effectively is prevented below the circumstance of 1/30 second, basically realized the government 4 archives defend the usefulness that tremble.
