With a 28 mm on a 35 mm film camera you get max 65 degrees FOV in landscape
and 46 in portrait
You can not make panoramas with only 6 images. Even in Landscape (most
people use Portrait.) you only get 10 percent overlap which is very
difficult to stitch. The less overlap you use the more important the
nodalpoint is. And to take them handheld is almost impossible
You should use at least 25 percent overlap which is 8 images in landscape. I
usually use morer than 30 percent.
Use a simple monopod to ensure you get as close to nodalpoint as possible.
For landscape there are lots of very simple ways to mount the camera with
the nodapoint at the rotation point.
