First 360 pano, home interior. Opinions?

Hi everyone, it's my first post here. I must say that this forum looks filled with people who like to help each other. I've got lot of reading to do!
I just tipped my toe in the 360 pano world. I don't have any specialized equipment, but I'm starting slowly. Here's my first official 360 pano:
www.dermandar.com/p/ejTZKa/maison-finale
As for my equipment, I'm using the following:
Canon 5DmkII
Zenitar 16mm F2.8 Fisheye
Manfrotto 190XCPROB
498RC2 ball head
DIY Pano Head
Here's two picture of my DIY pano head, let me know what you think:
I'm doing 6 shots (no Nadir/Zenith) around and PTgui stitches them perfectly in a matter of seconds every time. But I'm having a hard time doing the Zenith/Nadir shots, any help on this would be appreciated!
In any way, hope I'll get feedback from some of you!
Have a nice one,
David.

Well, your panorama is very good indeed for a first attempt, but it's not strictly true to claim that PTGui has stitched it perfectly, for there are several stitching errors to be seen. It's not quite clear what constitutes the "rotator" in your panohead design. If the rotating function is provided somewhere below the QR adapter on the ball head, then it will be difficult to easily set and maintain the alignment of the entrance pupil with the rotational axis to avoid parallax effects. Given the high quality of the rest of your other equipment, it would be a shame not to invest in a good quality spherical panorama head to match.

Hi John, thank for the feedback. I agree it's not perfect, but I was pretty proud of my first attempt. The rotator is not the ball head. The ball head stays level the whole time. I can actually rotate the whole setup, there's a ''pano'' feature under the ball head, with degree marked.
Any tips you could provide for my nadir/zenith shot, that's where I'm having problem stitching them together.
Thanks, David.

Yes, that's the bad feature of the design. Ideally you want the rotator directly beneath the wooden panohead.
The nadir can be taken as for any panohead. You will have to contrive a means of pointing the camera down at the area occupied by the tripod after the tripod has been shifted sideways out of the way. If you have PTGui Pro, then you can use the viewpoint correction option to compensate for the change in viewpoint. This tends to work best the closer the camera is to the original position. See:
www.rosaurophotography.com/html/technical6.html
www.ptgui.com/examples/vptutorial.html
www.johnhpanos.com/ptgvpt.htm
The zenith can be treated in a similar way if it's a flat area and there are features available for control points. It may be possible to add temporary features for control points in the shape of post-it notes or other sticky labels. Otherwise you may get away with manual positioning of the zenith image in the Panorama Editor window. Things are a lot easier with a spherical head .....

Rivest,
I started out with a pano head that was designed only for cylindrical panoramas. There was no provision to rotate up for the Zenith or down for the Nadir. That was fine until I wanted to start doing spherical panoramas. I purchased a NN3 for around $200 and have never looked back. Makes a world of difference using the right equipment. Although a commercially produced pano head is not required, it sure makes life a whole lot easier.

Thanks for those links, they were very informative.
Would you suggest I switch my 16mm Zenitar for an 8mm Samyang? I'd save at least the Nadir shot + the panos would be only for around instead of 6 (right?).

Well, I guess 200$ isn't that much for a pano head... But I'm very rarely doing panoramas. Ain't my business. For the few times a year I'm making them, I'll try to make my DIY work for me.

The Samyang 8mm will make you lose a significant amount of pixels on your full frame sensor www.360pano.de/en/samyang_5D_1D.html
As you have to move the tripod to make the nadir clear and take that shot separately, it will not save you a nadir shot.

I did read a lot of it, but I don't really understand how it is different from one? They both rotate the camera on it's nodal point in portrait orientation. What more could it do?
Or is there something I'm missing here?

Thanks for the link. I also have a 60D, so I could use it on it. But less resolution compared to the 5D.
