So a little while ago I wrote a blog post here about the G9s 6K Pre-burst function. My conclusion on this function was that whilst it had its uses its usability, for me, was very much degraded by what I considered to be very poor auto-focus speed. Further investigation of this issue has not, unfortunately, found a solution – the simple fact is that the 6K photo functions are essentially using video technology including the cameras video auto-focus which is hugely inferior to the lightning fast stills auto-focus system. Overall therefore I am afraid that 6K photo is for me a disappointment.
