Had ordered TacoRC 4 set (ND 4, 8, 16, 32) from Germany. Recieved within 6days - possibly because they were shipped from UK warehouse.. hence it was delivered quickly and without customs issues as well..
Extremely lightweight.. came in a very nice box to keep the filters..
Went out with the ND16 fitted on the P3A. By the time I reached the test spot - sun light dropped drastically.. Video straight out of the camera at ISO100, 25fps & 1/50sec was too dark.. Switched to Auto mode which recorded useful video at ISO 200 & 1/100sec. The video quality was very good..
The color reproduction (flowers, grass, pilot's shirt color) was perfect without any color distortion.. No patchy spots or any such issues.. The color reproduction as well as focus was uniform throughout the field of view..
Since I did not shoot any pictures, a few screengrabs from video are attached.. The first 3 screengrabs at instances where the P3A was moving very slowly, the last one when P3A was moving fast across the field of flowers.. Observations & comments on the picture quality are welcome..
Will do more tests with Nd4, 8 & 16 and upload in next days; Could help some fellow pilots make a decision..
