Canon EOS 6D write time problem

[Tex Gore]

Hi all,

I've not long since bought a Canon EOS 6D, and having just taken it for the first outing where long exposures were the order of the day, I've hit a problem. I have a Sandisk 16GB Extreme 45MB/s SD card, which I low-level formatted when I first used it in the 6D. I shoot only in Raw, highest image quality.

The problem is, the Camera is taking as long to write the image to the card as it does to expose the image. So, for a 3-minute exposure, I get a black screen with 'busy' for 3 minutes after the shot has finished. I timed it. For a 30second exposure, it's the same - 30 seconds of 'busy'.

I tried a different Sandisk card which was working perfectly in a friend's camera, and it was the same problem.

Does anyone have any ideas?

Thanks in advance,

TG

Long exposure noise reduction....switch it off

ABsolutley tun off. Some times called periphical illumination??? Mike

As above, basically takes another shot at the same exposure length to map out noise

No Mike, peripheral illumination correction is a different feature and shouldn't affect write times.

To explain to Tex what's happening.....
The body effectively makes a second exposure of equal time but keeps the shutter closed. It can then compare any "hot" pixels from the two images and remove the erroneous ones from the first exposure.
