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.
Greetings,

Hi Miro,
If I understand correctly, if you place the tripod on soft ground there is a problem, if you place it on solid ground there isn't. If that is the case, then the problem is not your tripod. It is just soft ground.
I looked up the head. Seems to be in the $€£ 40 league. Is it all metal? Anyway, that is not the kind of kit which will hold a 400mm equivalent lens without mirror look up. For that kind of application, in particular landscape work you should be looking into a heavy 3-way head to hold a 400mm equiv.
I would not expect buying a mounting bracket will solve anything on a weak head. It will move the slapping mirror further away from the support that it has more leverage to cause movement.
I also have my doubts on the tripod. Seems to be going for $€£ 80. No spikes under the feet. In summary you are asking to much I think.
Having written this, if you get decent shoots with that and with mirror lock-up, that is the way forward. For get auto-bracketing and shoot them one-by-one and let the tripod calm down between shoots.
My take. Joachim
