Hi there I have a problem with my sigma 8mm lens. it is the first time I used a fisheye.
The onlything I didnt had was a panoramic head.

What did you do wrong?:

You didn't use a pano head.

You didn't have the camera/lens set at the NPP; with your camera/lens combination this should be oissble without a proper pano head if shooting just a single row of 3 or 4 images. with a small positive pitch.

You are using APG 3.0.8 and not 3.5.

You are not using the ideal fisheye lens for your camera.

..............

You would do better with a proper pano head and a fullframe (as opposed to a circular) fisheye lens.

No Parallax Point - so that the camera/lens rotates around the entry pupil of the lens.

A proper pano head allows you to set your camera/lens at the NPP for multirow shooting.

If you are just shooting a single row then it should be possible using a simple rail on your tripod which allows fore/aft adjustment of camera/lens.

It is essential for the camera/lnes to be at the NPP whee shooting interiors with fisheye lenses, otherwise you can never achieve a perfect stitch.
