I have been using a 18 mm on a D70 but would like to minimize the number of pictures when stitching (18mm, 12-14 pictures in portrat mode for 360 degrees) so I'm thinking of going wider.
What are the main differences between Sigma 14mm, 15mm fisheye, Nikon 10,5 fisheye?
Would the fisheyes be useful when there are people near the frame?
I'm printing the panoramas with a printing height of 10" and lenght that is required.
Can anyone point me to any examples?
Thanks in advance
Lasse

The Nikon 10.5 is definently the best lens of the three, especially for the D70. Nikon's Capture 4 software does a great job of defishing the images. It corrects the barrel distortion and crops the edges. The lens was designed specifically for the Nikon/Fuji sensors with a 1.5 crop, so it will not work with a full frame 35mm camera.
I shoot with Canon 10d and 20d and a Sigma 8mm, however I ordered the new Fuji S3 primarily because I was very impressed with some printed panoramas my friend shot with the Nikon 10.5 and a D70. I also want more dynamic range, and the S3 is supposed to have it. We'll see. Since Fuji has not shipped the S3 to the States yet, I don't have any examples to show you, but this is a subject I have researched considerably, and I really like the 10.5.
Here are two links (not mine) that may help.

Just to let you know, when i tested the 10.5 on the fuji S2, Nikon capture would not allow me to debarrel the image. I have a hunch this workflow would not work for the S3 aswell. (so you might have to get a D70 
have fun

I use the Sigma 12-24mm on my Canon 300D.
You will still need to take 8 portrait images with the setup for the full 360 (and 25 for the complete sphere), but it's a nice setup.
And no need to defish every image..
If you'd like a specific example of this lens, just ask. But looks like you've got your mind set for a fisheye.

then D70 and the 10.5 needs 6 shots in portrait mode and you have a sweet cylinder qtvr or 8 images for a cubic. You can run a batch in nikon capture, takes 1 min, even paorama factory in auto mode stitches a perfect qtvr. I wish Nikon or someone would have mentioned this in some brochure :P im renting for the weekend and the first tests have sold me, doh!
have fun

GoneNorth/ TriggerHappy: My main concern with the fisheyes are with people who are at the edges of the frame and, when defishing, don't you lose some quality?
The links you gave GoneNorth are very useful.
TriggerHappy I would like to here your experience after this weekend.
Elja: I would like to see some examples of the 12-24. I have had that lens in my mind too.

no but you will loose some picture content at the edges after defish the 10.5 reports as a 12.7mm lens with a fov of 109° thus people close to the top/bottom edges in portrait mode will have their feet cut off. but that's the only way to feed these images in stitcher. usually I process these people panos with panotools where there is no need for defishing

for the money of that fuji s3 pro one can buy a used roundshot 360 filmcamera with changing lens-shift etc. 360-panoramas within seconds......! but our digital-stiching-friends seem to have a lot of time and patience and are are satisfied with minor quality.
i have seen testcomparisons showing contrast-control at fuji-stand which was more than confusing if not manipulated.
maybe they made a mistake with these quick shots/prints.

I have yet to see a full spherical from film that wasn't stitched in some way (not these lorez mirroballs) Andrew Nemeth does it with his Leica 4020.net/contents/ but it is scanned and stitched.
You say you shoot in seconds, but that leaves you with cylindrical panos on exposed film, I have produced some digital full sphericals in less than 2 hours from shooting to posting qtvr on the web. Maybe they are minor quality and people have been very polite with me so far.
I was at the kina on the roundshot stand and their top of range is a digital combo with a 27stops bracket exposure I wouldn't call digital minor quality anymore, although at a this price tag of 50.000€ I can think of more practical and cheaper combos.

Hi Lasse,
Here are links to my 360 photo's so far. These are all stitched from 25 seperate pictures. I can imaging having an even wider lens would be usefull, but a downside could be lesser image quality.
But I don't think this would be visible on web-size images.
The links:
- www.trumnet.com/360/fabia.asp
My first in a tight space and second or third 360 ever.
I know there are some stitching flaws..
- www.directshop.nl/360/
This is where I work. You can click on the doors to enter another room. I'm actually in some of these pictures.
- www.begraafplaatsennijmegen.nl/360/
This is my first payed job, the reason I got into 360 photography. It's still work in progress, there are only 2 out of five to come and I'm building a whole site around them as well.
These were all taken with the Sigma 12-24 on a Canon 300D using a Manfrotto 303SPH and a tripod.
Perhaps this isn't the type of image you'd like to see. If it isn't, just let me know what you would like to see.

HI Elja,
I too have the Sigma 12-24mm and I have run some test spherical panos thuoght Realviz Stitcher v.4 but have found that I can not get very sharp results. I have also read on the Realviz forum that Stitcher does not like the 12mm focal length.
I would be interested to know what stitching software use use with the 12-24mm, perhaps Pantools with a PC or Mac front end?

Hi Akkadian,
I use Realviz Sticher v. 4 (on a PC) also.
I have not encountered any difficulties with it, but I never tried any pano's other than 12mm with it.
I do use a Canon 300D/Rebel as camerabody, so the 12mm is more like 20 mm with the cropfactor. Perhaps this makes a difference?
