Panorama photos without Autofocus

Hello!

Someone told me, that I have to make panoramas without Autofocus. Is it true?
Do you create panoramas wirh or without autofocus?

thanks

Focusing towards infinity and then selecting manual focus works best in most occasions. Selecting an aperture like f:8 or f:11 to get a larger depth of focus will help, too.

Besides that, as Autopano can compensate for the slight changes in field of view different focusing distances are causing, one can allow some amount of focusing adjustment between one shot and the next provided it is small enough (so that a significant part of the overlapping region is in focus on both images.) Because I sometimes do that, I know it's difficult but not impossible. For most panoramas this is completely useless and a fixed focus works better.

The procedure depends on what camera/lens you use. With a FF camera and 12mm lens, at f/16 the hyperfocal distance is about a foot.

I would just set the lens to its hyperfocal distance at the aperture I need (i.e. f/11 or f/13 on APS-C, f/16 on FF).

As depth of field is what matters, here is a good tutorial about depth of field: http://www.cambridgeincolour.com/tutorials/depth-of-field.htm
