I'm finding that the data buffer to SD card transfer is too slow - almost 15 seconds after a 10 shot burst - during which the camera is out of action. After a single shot it is about 5 seconds before the camera is functional again and this makes it useless for sports photography. The burst mode fixes the focus on the first shot and you can't take individual shots due to this slow data transfer. Even if the firmware allowed 10 individual shots to be stored before making a transfer it would make the camera very much better. If anything the camera appears to be deliberately hobbled in this respect.
I'm using a class 6 SD card. I'm thinking of spending money on a faster card but have doubts about that helping.
This seems to be the biggest weaknes of this particular camera and it is frustrating me enormously. Once again I've bought a bridge camera hyped up to be excellent for sports photography (skiers coming towards me!) and it just doesn't cut it at all - not even close.
If anyone has any suggestions how to improve this - other than Sony un-hobbling the firmware then please let me know. If anyone can hack the firmware and correct this problem then even better!
