I am shooting timelapse sequences with my 1Ds Mark II and the TC80N3 controller. My exposures vary from 15 seconds to 1 minute in length. I have noticed that a 15 second exposure takes 15 seconds to write to my memory card. A 1 minute exposure takes an entire minute to write my memory card. A normal exposure writes quickly.

The problem with this is the buffer fills up quickly and won't take any photos until it finishes the long write.

What's up with this?

It sounds like you have noise reduction turned on... (See page 129 in your user manual).

After your main shot, the camera will take a dark frame exposure of the same length with the shutter closed.. The noise in the dark frame is used to mask out the noise in the shot you just took. If you turn off noise reduction, then the delay should stop.

Yep - Jim_T hit it on the head. Turn off noise reduction in camera.
