Hi @tank104
After checking the image you attached, I would like to know if this picture was captured when the drone was moving or not moving. If the drone was moving, can you attach another image which is captured when the drone is not moving?
Imx519 is using rolling shutter which could cause Roller effect and can not focus very well when moving.

Hi Dion,
Thanks for responding. We have tried it both when hovering, and when moving. When hovering though the drone does still slightly move as expected with a drone. However both times still get the effect. Its not always though - sometimes moving and hovering the capture is great.

Is there a better camera you can recommend for my use case though? i.e. taking aerial shots between 60-100m whilst still and moving?

Hi @Dion ,
Just wondered if you had any update on this thanks.

I can recommend the global shutter camera below:

Thanks! Sorry for late reply I didn’t get any email that was responded.

Is there any larger MP camera version ?

HAd a search and that does look like highest resolution - thanks

Hi, I purchased two R0234 cameras; the website says:

Focus Type Manual Focus

But the lens is firmly fixed by the look of it; how can I manually adjust the focus?

Hi @bengou
Can you find solidified liquid glue in the M12 Lens? If so, you can use hot air blower or haid drier to melt the glue.

oh, ok that’s the way the. thanks for the clarification
