Hey everyone so I am having an issue with the high speedy Burst mode shooting. Both with or without the CF card in the camera, The burst mode will sometimes be super fast and then will slow down on its own and I get the busy warning when it slows down. I have noticed that when I moved the camera from side to side or up and down it affects the burst rate. Is there something I am missing ?? I have try many shutter speeds and the same problem occurs. Please Help!!!

Thanks

The 7D can only fire 20 something RAW shots before filling the buffer. The camera will slow to a crawl while the buffer is emptying. After the buffer offloads to the card the camera will go back to full speed. Moving the camera has no effect on shooting speed.

But what I find weird is that sometimes the burst starts slow and not fast???

it has to do with light hitting the sensor, Set it to manual with a high shutter speed (1/8000) and continiously shoot while moving the camera but pass it through a bright light and it will go from slow to full 8fps.

Ok so defnitely had to due with the light exposure. I tested it pointing both at a bright light then a black tv screen and right away it was apparent that light made a difference.

Thanks everyone for you help. So glad it wasn't my camera being messed up :)

check the settings - you can set AF priority (shutter speed vs focusing priority)

Yes, but that's not the issue here. The iFCL implementation in the 7D slows down continuous drive speed when aiming the camera at dark subjects, regardless of other settings. That was already established furter up this thread.
