    Hi Nazrin,

    The SX260 is a terrible camera for AP. Even with the smallest amount of vibration it is impossible to get sharp pictures. The vibrations are transferred to the lens, and the lens actually vibrates blurring the pictures.

    I dropped it for a camera with a fixed lens and have never had a problem since.

  • Could you please provide the parameter again?

    your link does not work.

    Thanks, 

    Juan

    Hi Nazrin,

    I'm using a Canon SX230 with acceptable results :

    The picture was done over a sunflower field, at 110m altitude.

    If you want , try the parameters that I use:

  • Hi, Nazrin

    Have you solved this problem? I'm suffering from the same blur issue. If so please let me know how to get it. Thanks in advance

    • Hi Alex,

      Do you have a live link to your parameters?  I'm using a Canon SX260HS on a 3DR Iris + and using KAP UAV script to take images for stitching.  Images are okay but not as sharp as what you've posted above.  Thanks,

    Also set focus to infinity and lock it. This will speed up the reset ready for the next photo.
  • I am using SX260 annd SX280  and pictures are ok.

    ISO 400, shutter 1/2000, EV 0.

    Airspeed 10-12 m/s, flight level 100-200m

    • How trigger the sx280, I am findig the chdk for that, and nothing.

      thanks for your help

    • Marek,

      Are you shooting in manual mode?  I see above your ISO and shutter, what F stop?  And lastly, how are you / do you look the focus to infinity?

      TIA,

      Tim

      • Hi, 

        normally using time (shutter) priority so f-stop depends on light conditions
