Are there any people who make pano/ mosaic using a >400mm (35mm eq.)? I want to know the practical minimum percetage overlap you use in the field. I can imagine some vibration in the tripod and pano/tripod head due to mirror flipping and/ or some winds. This may change the angle of the lens (let's call it vibration angle) and reduce the overlap in some direction. Depending on the angle of view of lens (fov), this vibration angle can be a significant % of fov. On the other hand, due to the small fov and the large number of shots to take, I would like to keep the overlap to minimum.
So any one have some real experience to share?
Thx a lot in advance.
As Georg said already: at least 20%, better 25-30% with long lenses. Mirror-lock is an absolute must and also is a very sturdy tripod and pano-head. I sometimes put some weight to the tripod-legs and hang an additional weight
to the end of the center-colum to pull the mass-center down deeper.
IF you have vibrations that might influence the overlap you can be absolutely sure that the shots are ruined anyway - so the overlap is one of your minor problems . . .
:cool: JosefÂ´s new had has built-in sensors which realize any kind of vibration and fire the camera only then, when theyÂ´re gone (can be deactivated of course for fast shooting using short exp. times).
What head are you using?
