Do I need to upgrade my 360 pano head

I have been using a 360 precision pano head with a 1Ds2 canon camera and a 15 mm fisheye lens. I have enjoyed the combination very much.
I have recently upgraded to a 1Ds3 camera. I have tried a sample pano with the 360 pano head. I do not see any parallax errors. Does anyone know if it is necessary or worth upgrading the 360 pano head with a new arm to match the new camera?
Thank you for your help.

HI John I have tried rendering the panorama without the fast transform and I still get the small gaps/holes in the panorama. I am using Dorin's method described above.
A further question: When Optimising in PTGui I have had to add points between pictures when I then optimise the numbers can be large 15-17 is this normal? In PTMac such big numbers would mean very poor alignment.
Best wishes

Hi john I will give that a go thank you for the input. I have tried the method described in the email above of renaming the folder and it worked perfectly. It is a bit of a bother to do the setting up of the different folders and then renaming so if you suggestion works then it will be great.
Cheers and many thanks

HI John,
The gap is a small rip like hole in the panorama near where the top image joins with one of the images that moves around.
I emailed PTgui support with pictures and examples of the panoramas and the hole and this is the response that I recieved. I am assuming that there is a small glitch in the program that causes the problem, as I have checked and there is overlap where the hole occurs.
Email response from PTGuit support:
Hi Richard,
The next release will include a fix for a bug that might be causing this problem, please keep an eye on www.ptgui.com/beta.html .
But just to be sure: have you checked that the images are actually overlapping around the problem spot?
Kind regards,

PS i have not yet tried the suggestion of using seperate folders and then renaming them to create the panoramas for each different exposure level.

Hi,
I will have to try out your suggestion to see if it makes a difference to the rendered pano. I will let you know once I have done this!
Thank you for the reply.

HI I am a new user to PTGui (for Mac), but have and use PTMac and Stitcher before. I wanted PTGui as it has a more sophisticated auto stitch than PTmac and its template feature meant that I could create a template that would allow me to make HDR images by stitching one panorama and then apply the template to the other panorama photos taken at different exposures. I would ultimately like to make a template that would allow me to stitch new panoramas quickly without having to place control points, but I am hoping that I can do this later.
I have been able to get some very good stitching results from PTGui using the auto placement of control points. After a few rounds of optimising, and removing control points that have large values I am able to render a panorama and the resulting pano has no visible errors at 6000 by 3000. I am very pleased with the results. But If I apply the same file to the next group of photos taken at the same time but different exposure (e.g., one stop brighter) the resulting rendered panorama has a split (a small missing gap). This happens each time I try using a stitched panorama as a template. Do you have any ideas on what might be happening and how I might fix this?
I am using a Canon 1Ds2, 15mm fisheye lens, and the 360 pano head.
Any thoughts and help would be very much appreciated.
Best wishes
Richard

Last night I spent some time adjusting the camera by rotating it so that it looked straight down at the central column of the pano head on the tripod. When I did this I was surprised to see that the central sensor point was not on the centre of rotation. I then adjusted the camera to correct this. To do this I used the bottom slider that allows you to move the camera left-right: This placed the sensor directly over the centre of rotation. I then used the plate that attaches the camera to the top back-forward plate. This allowed me to centre the lens/camera over the central rotation point. I took several photographs in this position. When I looked at them in Photoshop I drew lines that bisected the picture from each corner. They met very close to the centre of the central column.
Since doing this careful realignment I have found much lower levels of parallax errors. I can now get good alignment in both horizontal and vertical rotations.
Thank you for your help!

Finding the entry pupil Canon 15mm Fisheye on 303SPH

I have been struggling to find the entry pupil on the 15mm fisheye lens. I am using a 1Ds2 camera. I have been trying to follow the instructions from Manfrotto for the pano head. It suggests that you should first adjust the vertical movement of the camera with the top sliding plate so that there is no movement of foreground and background objects when you rotate the camera up and down. This is relatively easy to achieve by moving the camera forward or backwards with the top sliding plate. This should in theory have helped me position the camera and lens so that the entry pupil was aligned with the centre of the vertical rotation. So good so far!
I then started to align the horizontal rotation of the camera. According to the instruction manual this should be accomplished by moving the camera left or right on the bottom plate. I think that what I am trying to achieve is to position the camera and lens so that the entry pupil is directly above the centre or rotation in the horizontal direction. I have found this impossible to do. If I just use the left right movement I cannot get foreground and background objects to align correctly. I need to move the camera on the top plate as well to stop parallax errors. But when I move the camera on the top plate vertical rotations are no longer aligned. I can either eliminate parallax alignment in the vertical direction or the horizontal direction not both. It seems that the entry pupil in the vertical direction is different from the one in the horizontal direction!
Has anyone else had this issue? Is it possible to fix this problem? Has anyone had success with a 303SPH and fisheye lens to get good alignment?
I would appreciate any feedback or kind words of wisdom. Thank you reading and for any thought!
Best wishes
Richard
