Don´t know which kind of array you´re talking of. You need around 4-6 fisheye-cameras and the array is set up in seconds on location.
We´re are testing 5MPx-cameras with 170° diagonal FOV which can do stills and movies. Once assembled they stay an array.
No problem to trigger them all at the same time.
First tests went good - need a lot of fine-uning of course. You definitely can´t do any gigapixel this way . . 
- but for usual
displaying it´s very fine. And it does 360° movies too . .

But you can! In fact it´s better doing such motifs motorized: you don´t need to stay beneath the camera for releasing and moving it around.
You start the sequence and move out, let the head work alone. ESPECIALLY in very small locations that´s a great help!
For shooting "action VRs" you need an array of cameras to cover 360x180 with ONE shot. Some people do it already - we´re testing an array actually

I have to agree with Klauss, I did a day shooting small interiors of small yachts and boats . Really difficult also as you have to go to the camera after eacht shot.
At the moment I am really looking at the Panomachine 7.0. Without arms it is 1180 euro without VAT. Can put my own nodal Ninja on top of it and have it make a circle automaticly. Seems like a good compromise, also as it will allow me to do the nadir like I do nowadays.

Hi Klaus,
I know this kind of setups from studios. What I wonder, how are the parallex problems? Do lines in small rooms stay good, or is there a minimal distance that has to be observed?
cheers,
Hans

I have retrieved my dino from the closet to see what the VR drive can do. So I mounted it as shown below. (You woldn't do it like this, would you?)
Did the VR drive swing it ? Yes it did. No problem.
Normally you would use the lensmount, and I guess the VR drive can move some really heavy equipment mounted in a balanced way.

I know them too - worked with it - but they´re quite different . . .
It´s possible to find a common setting for all cameras in the rig. But it´s not working on minimal distances - we´re testing.
Those rigs, which i´m speaking of are thought for the use above, let´s say, 5m - with some help of routines in the application
They are NOT thought for the use inside small rooms . . .

Yes - definitely it does. I tried it at the Photokina. It moves about 4Nm afaik. That´s heavy load!
D3x with a 300mm was no problem. Fine piece of engineering!

Leif - shooting gigas with apertures wider open than f8 is a no-go i my eyes. Even with nightshots i take f8 as a minimum - but i definitely prefer f11/16 with lenses
between 35 - 85mm for full-spheres. Gigapixel-mosaics with 200-300mm i usually do with f11.
Modern cameras work very well even at 800ISO and some work very fine at 1600ISO.
I anyway use only prime-lenses which have absolutely no vignetting from f5,6 up. So i never need to correct them - neither for CA nor for vignetting.
These lenses are somewhat more expensive - but they save you a lot of time by not having to correct them. So in the end they´re cheaper!
best, Klaus
I shot a gigapano with a Canon 50D and a Canon EF 100-400mm F4.5-5.6L IS USM
400mm 1/500s f8.0
http://www.rundskuer.no/krpano/orstafrapolsa4.html
I hoped f8.0 would do it since the 50D has crop 1.6. But no. You can see the mosaic in the water.
I have read somewhere that the human eye is very sensitive to repeating patterns. And it seams like the patterns gets more visible when the pano is moving.
That means panos are even more sensitive to vignetting if they are interactive instead of stills.

No. With a still you look longer at the same picture - so you have more time to recognize faulty areas.
The lens you mentioned isn´t soo bad at all - but f8 at 400mm is just one step closed on the other hand . . .
But regarding you anyway use the "sweet area" of the lens with a crop-camera you shouldn´t have ANY problem
even at f8.
So i´m not convinced it´s vignetting! Did you post-process the shots in a RAW-converter? Dis you use any settings beside of RAW-conversion?
Maybe you better don´t do it this way.

I also doubted it was vignetting.
The pano was shot in RAW and the files were converted to TIF using Canon DPP, with default settings.
In another thread, http://www.kolor.com/forum/t13354-burj- … -gigapixel
I have tried to find out what it is, in "my search for a smooth sky".
As you can see Alexandrej has no doubts : "Quite for sure, this is vignetting. It gives these typical darken zone at corners of images."
After reading Destiny's suggested reading : http://www.archiphoto.com/personal%20pa … tting.html
I am confused. This reading concludes that there is no such thing as a lens with no vignetting, because of the law of physics called "cos-4th law".
The proof of the pudding is the resulting interactive pano.
I will try f11 and f16. In many cases, low light conditions, this will not be an option though.

I see - LOOKS like vignetting indeed. But a lens which is designed for a fullframe can´t produce such a vignetting on a crop-camera at f8 i suppose. Or it´s not worth a dime, sorry - or it has a defect. I guess we´re still talking about your Canon EF 100-400mm F4.5-5.6L IS USM!?
So something might be very strange here.
How exactly did you process the files ? Did you try them without any processing? Did you try a different converter?
I had such an issue once - whe i used the "360image" setting in Photomatix. This setting produed axactly ths same "vignetting". After that i realized that it meant to
"close" a 360° equirectangular and NOT to be used with images to be stitched.
Or are we talking about a different lens? It´s a bit confusing me . .

In the other thread it is not about the Canon EF 100-400mm F4.5-5.6L IS USM
I have used severel lenses there , e.g. Panasonic Leica DG Summilux 25mm f1.4 ASPH lens.

The gigapano at http://www.rundskuer.no/krpano/orstafrapolsa4.html is shot with the Canon EF 100-400mm F4.5-5.6L IS USM to CR2 files
I have tried to process the CR2-files directly i APG but the result was ugly (june 2010). Therefore I converted the CR2-files to TIF using Canons DPP software.
Maybe I will try DXO and Lightroom some day.
btw: have I read somewhere that it is planned a LR plugin for APG ?

Yep there is one - but when i tried to intall it on my MacPro some time ago the installation crashed . .
So i didn´t give it another try Maybe it works now - never cared again because i don´t need it.
I process my RAWs in CaptureOne or in Lightroom and export them as TIFF or JPG for the use in APG. Never had ANY issue with lenses.
Did you try ColorCorrection in APG? Usually it corrects such issues with un-even density perfectly!
What camera/lens did you use with the vignetted shots (you wrote "several")? Can you pin down the lens/camera
which you used for this shots?

Ok - sorry, i mixed it up with the Canon 50D and the Canon EF 100-400mm F4.5-5.6L IS USM - because in that case i´d be extremely surprisd to see vignetting @f8 . .
With the Olympus i don´t have any experiences - but also i´m a bit surprised about the vignetting indeed. Guess you´d either have to use f11/16 or a centerfilter . .
or to switch to another system.
Seems even DXO can´t solve the problem, does it? Does DXO have the correct curves for the Leica lens?
I just donwloaded the images you linked to in the oter thread - APG shows me 12,5mm and a factor of 1x . . . guess that´s wrong, is it.
What chip-size/crop does your Olympus have (i don´t know the camera)?

The ORF-files were converted with Olympus Master software, and it didn't recognise the panasonic lens. Therefore there is no lens-information in the file.
The beauty of MFT-system is that I can use whatever lens I want to the sorrow is that there is no lens-information in the ORF or TIF, the combo is not in the DXO database and there is no corrections done in the camera before the pics are save to the card 
The E-P3 has crop 2.0.

Indeed, a beautifull device to create high quality panoramas. The small nadir is not that much a problem although for the price one would hope there is a way to make the nadir shot. It would be enough if you can place a ballhead between tripod and the lizardq, tip the whole installation 90 degrees, cracnk up the tripod a number of cm and make the last shot. this would be too much effort for most panoramas where the floor is not that important but a nice solution for when you want the best.
Maybe the lizardq people can make an automatic expansion to their device..........idea copyrighted by Destiny and Hans Keesom :-)

As they are german, I am closer. could pick up a set by car, it is only 500 KM, so cost me about 190 euro on fuel to pick up.

To check if this is right I have collected three footprints. The first two from this thread and for LizarQ I downloaded their sample: 1-Meadows.jpg
Then I converted it to qube-faces and this is how it compares. I'm not impressed.

The VR-drive´s footprint seems to result from shorter lens. The one from me was done with a Canon 15mm fisheye, LizardQ uses the very same one.
It depends on the vertical tilt - Josef set it to -12° and i shoot 5+1 images @20% overlap. That works very fine. LizardQ also shoot 5+1 as i recall.
I guess Seitz a) has more than -12°, but has to add one or two more shot(s), b) used a shorter fisheye or c) didn´t use a fisheye at all in this sample.
When i use my 35mm lens for a full sphere on Josef´s head i also get a much smaller Nadir - looks very much the same like the Seitz example.
I will add an image later. Josef made the vertical arm a bít longer in the final version - so the down-angle is more steep.

From my own perspective the most economic solution seems a automatic pano head on which I can place my NN5 so it will do the rows automaticly but I will have to change the vertical after each round. Using the Nodal Ninja Nadir Adapter I can then easily make brilliant panoramas while keeping a great Nadir.
The MK Panmachine offers me such simple machine for 1180 with VAT, so that would be 1404 euro incl VAT
The VR Drive 2 will cost me 1800 (incl VAT?).
Are there any reasons to convince me buying one or the other?
Does my thinking misses something?

That´s what i also guessed when i told about my use of a 35mm. It´s obvious that a 35 or 50mm havs steeper downlook-angles than a fisheye.
Therefore the Nadir is much smaller. Test the VR-drive with a fisheye and the Nadir will look exactly like the one from LizardQ or Josef´s head.
