I used to use Gigapan in conjunction with Nikon D5100 camera and Samyang 8mm lens. Unfortunately, Gigapan turned out to be incompatible with the camera and the lens (I shoot indoors). The main problem was that I failed to set a perfect nodal point and could not get 100% sharp panos as output. The nodal point could only be set in such a position that parts of Gigapan were in the picture, which is unacceptable.
I am thinking of buying Panogear instead. I am determined to keep using the camera and the lens. Would I have the same problem (setting nodal point 100% perfect) in Panogear?
P.S. How useful is the touchpad? How does it affect the shooting speed?
As Andrew stated already: the Merlin (Panogear) has a very big base due to itÂ´s battery-holders. So using a fisheye-lens isnÂ´t really wise on it. I also suggest to use a manual head instead IF you only use a fisheye.
For fisheyes on "robotic" heads you need one with a vertical axis very close to the rim of the base - this way the Nadir "hole" is very small because the cameraÂ´s/lenseÂ´s downlook-angle is very steep - look at the image:
the black plate in the center og the tripod is the Nadir-hole of my head.
These holes - aka "footprint" - easily can be retouched or merged with an extra Nadir image. But editing the very big black area which the Merlin produces using a fisheye is much more complicated - depending on the floor.
I used the Merlin in the beginning also with a fisheye - stopped doing so very soon.
