I mean Canon much easier to setup than Optio, before CHDK we used to tape down the shutter on cameras that would fire continuously if you did that. The Optios were one that would.

Yes an off centre prop hole will cause vibration, did you open up that hole yourself? APC's are normally very good. 

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

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,

Kamille

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

thanks for your help

Could you please provide the parameter again?

your link does not work.

Thanks, 

Juan

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.
