Sonic said: Hey, everyone!
I'm currently using a Nikon D90 + Nikkor 20mm + EpicPro robotic panohead to shoot indoor spherical panoramas and ptgui to stich 'em
This is not a setup I'd choose to shoot indoor spherical panos.
Using a 20mm rectlinear lens on a Nikon DX cropped sensor body means you will require alot of images to cover 360x180 (a min. of 32 images?) and the FOV of each image will be relatively small (compared to a fisheye). So you will have a lot of seams and a lot of potential for images lacking features for automatic control point detection, for example on plain walls and ceilings.
Furthermore when shooting sphericals it is desirable to reduce the number of images per row as you approach the zenith and nadir to avoid excessive overlapping which can in itself cause problems when stitching.
As far as I know the Gigapan Epic Pro robotic pano head can only shoot a regular matrix/grid of images so you'll probably have excessive overlaps as you approach the zenith and nadir. It has a pretty large nadir footprint too.

I really have no idea what this stuff is worth these days.
Is £275-300 for the Nikon 10.5 fair?
Cheap. I think you'll have no touble finding a buyer at that sort of price.
and is £275-300 for the Absolute fair?
More difficult to price because the Absolute is tied to camera/lens combination and the D70 is rather ancient these days. So most buyers would need to factior in cost of upgrading the head for another camera body.

Savak said: Hi Dorin
Thanks for the quick response.
No I don't have the Canon still I had to use it to purchase the Nikon but don't fancy another £150 to up grade to the D5100.
Any thoughts about the subject line? How plausible for resonable results?
Graeme
Why don't you just try it and see?
The AEB capability of most DSLRs offers insufficient range for pano shooting anyway.
Check out the Promote control if you want extended exposure bracketing:
www.red-door.co.uk/pages/productpages/promote-con...
By the way neither the D3100 or D5100 will autofocus the Nikkor 10.5mm fisheye lens as they both lack an in-body focus motor. Not that this matters because you would never use autofocus when shooting panos with this lens.

Tom Brown said: I purchased the NN3 from a Canadian vendor who was a very nice guy but sales, only. When I asked him about the detent issue, he nicely steered me to the main site where my inquiry did not result in a civil response.
How strange. NN has a reputation for exceptional customer service and that has certainly been my experience. I wonder what you could have said to elicit a less than 'civil' response.
Mostly, I'm looking for something small and portable... like the NN3... lol! It would be nice if it had the capacity to leave the battery grip on.
It's not going to be small if it has to accommodate a battery grip is it?
I'm less interested in compensation for the offset tripod mount of the Pentax battery grip (or the Pentax body, for that matter). It's been years since I've taken a multi-row pano. If I wanted that kind of coverage, I'd just shoot with a wider lens.
So you only wish to shoot single row panos? What lens do you use now? And how many click stops will you need per 360 for your lenses?

NeilPatel said: How many shots would be good enough for Sigma 8-16 lens?
Welcome to the forum...
This is a pattern for the Sigma 10-20mm at 10mm so it will give you a fair idea:
Recommended (1.5x, 1.6x): N, 4 images every 90° at -60° pitch, 8 images every 45° at 0° pitch, 4 images every 90° at +60° pitch, no zenith image required.
For other lenses see:

Hans Nyberg said: I assume that your Panotour has the same options somewhere.
You need of course to have the original krpanoiphone.license.js in your source folder together with the normal krpano.license
If you do not have that you will get the demo watermark.
Hans
No - things are not quite like that with Panotour Pro.

Hans Nyberg said: From the Panotour Pro dokumentation
www.autopano.net/wiki-en/action/view/Panotour_Pro...
"This feature is only available to registered users."
Sounds rather weird to me as you buy the Panotour Pro with the license for HTML5 devices.
If they demand you to register the software for this they should make this clearly pointed out when you buy it.
Hans
If you don't register (enter) the Panotour Pro license key within the software then it remains in demo mode.

pranshu14 said: Hello members,
I am planning to buy panotour pro
and my main aim is to run this the tours on ipad.
but i need little help about setup.
May I suggest you ask questions about Panotour Pro on the Kolor forum because you are more likely to get answers from Panotour Pro users there. There sia topic dedicated to the use of Panotour and Panotour Pro
www.kolor.com/forum/
However the basic process is to use the generic HTML template when building the tour using Panotour Pro and directing the output to a new folder and then upload all the contents of that folder to your Web server maintaining the file/folder structure.

Doug Aurand said: Didn't say it wouln't work
But with a 15-20° tilt up and down, wouldn't the two rows be overlapping about 60%?
That seems like a lot of unnecessarily duplicated pixels on a lens as clear, sharp with as little falloff as the Nikkor 10.5mm
I shoot the lower row at about -15 and the upper row and about +50.

This is my preferred pattern when shooting panos in domestic scale interiors - it seems to provide the best stitch in such circumstances - for me.

radphotos said: How is the gigapan system? gigapan.com/? Can you make tours with this technology?
I really like the Sigma 8mm. I reasearched it a bit and it looks awesome. Although with that gigapan system I can supposedly use a regular lens. ex. 18-55mm zoom. Any feedback?
The price would probably work out about the same from what I see.
The Gigapan series of robotic pano heads is not designed for shooting spherical (360x180 FOV) panos. They are designed for shooting high resolution partial panos (with FOV of less than 360x180)typically using longer focal lengths.
Gigapan heads can only shoot a regular matrix of shots but when shooting spherical panos it is desirable to reduce the number of shots per row as you approach the zenith and nadir to avoid excessive overlapping.
The Gigapan series of robotic heads also have limits to the max. positive and negative pitch angles that can be achieved, and they also have a relatively large nadir footprint.
You would need to use the Gigapan Pro head to support your Nikon D90.
'Kit' zoom lenses, such as 18-55mm, are not really suitable for spherical panos for all sorts of reasons, not least the fact that you need to shoot (process and stitch) so many more images than if using a more appropriate fisheye lens.
