Hello Alvarez,


Samyang | 8mm
VFOV (max - min) 185°
HFOV (max - min) 185°
DFOV (max - min) 185°

Shooting Set-up
Recommended 1.5x crop 4 photos every 90° at 0° + Z + N

The Best way to operate is on a monopod turning by hand every 90°

Not necessary to use a Merlin/Panogear for this kind of picture ...

It´s rather counterproductive using a merlin with a fisheye. It´s base is so large that a very big Nadir-hole occurs.
Also in terms of speed a manual head is preferable.

XML files for positioning is obsolete in 95% of all cases using a fisheye - it´s FOV is so wide that correct matching control points usually can be found automatically.

Unless your setup is such that you cannot reach the pano head to reposition it - shooting on a pole, and so on.

Using a fisheye on a pole the Merlin´s big base gets even worse. I tested it years ago: the bigger the head´s base the lesser you see from the ground - which is quite logic.
And that´s definitely not what you want using a pole . . .

No - for shooting with a fisheye on a pole better use either a motorized head providing a rather small Nadir-hole - Seitz, Dr. Clauss, Panoneed - or use a manual head with the camera set slightly angled or just a ring and put marks on the lower part of the pole for orienting during spinning the pole. That´s common use.
The problem with a manual rig on a pole is shooting the Zenith - but there are tricks which help here.

Believe me: using the merlin on a pole with a fisheye really is suboptimal . . i realized that by doing it ;)

best, Klaus

You are correct of course.

I was really 'talking generically' about fisheye lenses and robotic pano heads.

I see. The Merlin is somewhat "special" in the range of pano-heads. But it´s a great device!!

best to you, Klaus
