Auto Exposure Bracketing problem

[yoshiharra]

I am shooting mosaic panorama with papywizard/Orion mount. Papywizard set to fire the shutter (via Orion) once every node of the mosaic. I have setup my EOS T3i to shoot AEB 5 frames every node (manual mode, manual focus), with 1 step increment. Sequence of exposure set to 0, -, +, --, ++.

Every time I shoot, I get first two frames exposed at 0ev; not 0ev, -1ev! I don't know if it is a bug, or I am doing something wrong! I have to say, when I shoot manually (by pressing the shutter myself), all frames are exposed as expected!

I appreciate any help.

Thanks

Anybody! Nobody?

I don't know what you mean by rev. Perhaps the external trigger is interrupting the bracket. Could you give example of a sequence of exposures? Are Canon and ML bracketing both enabled?

Sorry for delay to reply as I was out US.

Sorry about the typo, it should be rev, rev!

Bracketing is only enabled with ML, not canon. Sequence of exposure set to 0, -, +, --, ++.

Thanks
