This is really frustrating.

I was out and about today, and yet again I was cursing the camera for not having a 'just take the shot NOW' button.

I was taking shots in quick succession (shooting RAW, camera set to 'P', no fill-flash, daylight, sunny day, auto-focus) - But I found that 2 or 3 times, when it came to shots that I really wanted, (like when people had that perfect expression) the shutter wouldn't fire and I lost the moment. I was getting focus lock, but no matter for how long I kept the thing pressed it wouldn't take a shot. And then suddenly, after about a ten second delay with my finger on the button I got a click.

I *think* I've managed to recreate the problem here at home. If I shoot say twenty shots continuously I get the 'r00' indicator in the bottom right (I think that's the shot buffer indicator) - It counts back up to r04. But then, even when I keep my finger on the shutter there a further 6 or 7 second delay before it takes the shot. But this is the exception rather than the rule.

What normally happens is the first 4 shots fire quickly, and then (if I keep my finger on the shutter) the following shots have about a one second delay between them. Nothing like the 10 second delay I got a couple of times today. Unless, it was a combination of auto-focus hunting and raw buffer and my panic attack making 3 seconds feel like 3 hours...

So, my question. It is better to let the memory buffer recover fully before trying to shoot again? Okay, it only takes 4 seconds, but I think that's whats causing this issue.

Hmmmm.... Answering my own post here. A sign of insanity.

I've gone back and checked the EXIF on the shots which were 'delayed' and they indicate I was using a -3.0ev fill flash. So.... it could have been the flash trying to recharge? - Would that prevent the shutter firing if the flash wasn't fully charged?

The camera may have been writing the RAW files to the card, in which case the camera will not fire. Shooting Jpeg will let you take far more pictures before the buffer chokes up, but you loose the flexibility of RAW. Not sure if that will help.
