Thanks for the reply Popo.
Due to the fact that central weight is not at the camera tripod mount, a several problems occur.
1. Focus frame is moving down in case that tripod is placed in slightly soft surface. In case of asphalt, concrete and rocks it works fine. When I compose image I off-load the tripod from front weighted camera-lens. When I tighten the ballhead and release the camera the frame is moving down.
2. Some motion blur appear at pixel level. Again due to the off-centered weight the tripod is not as stable as equally loaded tripod at all 3 legs.
3. I cannot perform Exposure bracketing and mirror lookup at my Canon 50d and 400d.
4. The off centered camera lens requires to tighten the ballhead firmly.

1. Press the tripod down well before you shoot.
2. Use cable shutter release, it stops the camera from moving.
3. Yes, of course you can. I can do it on my former 350D, my sister's 400D and my 450D. No idea why you would think you can't... they do not cancel each other out. Do use a cable shutter release, else mirror lock up will not make sense much. Of course, mirror lock up requires 2 shutter release button presses per bracketed photo, so 6 in total. Or, alternatively, set the timer to 2 seconds, then the shutter will fire 2 seconds after the mirror went up. If that is enough for your tripod/lens combination I donot know (the 2 seconds), but you can of course try that.
4. yes, it does.
