detent design: spherical pano vs high resolution mosaic

Hi Everyone,
In order to design better and lighter pano bracket, I need your help in detent design. I know most people here are interested in spherical/ cylindrical panos where shooting interval of 36 degree (10 shots) to 90 degree (4 shots) is enough. but is there any one also interested in making high resolution (such as > 100MP or 1 GP) mosaic using long focal length lens where shooting interval of less than 10 degree is desired?
thanks a lot in advance.

That would be cool. But I am still trying to do 6 shots with my D70/10.5mm.

Hi Nick,
I shoot panorama's from time to time using a 5 degree or sometimes even less interval. When I use a pano head for this I'm using the 303 SPH and it's rotator. However many times I just shoot this handheld as well since I'm using a 70-200mm lens and it's only done for landscape type of work. The DOF is so shallow anyway that I'm not sure I would ever try to use a setup like this to capture an interior or scene where there were foreground objects too. And I have no plans to try a full spherical with this, just "normal" panos.
But, none the less I have been after the 360P guys to add support for a 70-200mm zoom, so yes support for a larger zoom would be great. But the detent interval may not be the biggest issue, a much longer length of the base arm and ability to support much more weight is also required. At least in the Canon line of lenses a 70-200mm zoom with IS is quite heavy. Also the attachment would not be from the camera but the lens collar attachment.
Regards,
Robert

Yes, I definitely would like to see many detents for hires mosaics. This is true for horizontal rotation and even more for vertical rotation (just in case you plan to develop detents for vertical)
Long arms for long zooms are not needed due to 2 reasons:
1. The lens/camera combination should be mounted at the lens and not the camera, so it will be much closer to the rotation axis (makes it also much more stable)
2. For long focal lengths the point of no parallax is not critical.
Yes, long focal lengths and close-by sceneries are a problem due to the shallow DOF. Works best for hires land- and cityscapes.

thanks a lot for all the helpful replies. 2 more questions, what is the smallerest angular interval you want to see in the detent system? what is the usual angle of view in your final stitch?

We can easily build a head to support 5º increments on the horizontal base and 5º on the camera arm. We also have a custom mount for the Nikkor70-200 and could easily modify it for use with the Canon 70-200 if requested.
We could probably go down to 3º increments on both axes but that would require a few more design modifications.
You're right about the weight, I've yet to see another head that can accommodate at 1DsMKII/70-200 lens without any problems.

Someone correct me if I am wrong but if one is using a 200mm zoom or other lens with a lens mount is it not going to be unecessary to mount the whole setup on a vertical arm in order to get portrait orientation? That is, why wouldn't one mount the lens flat and then rotate the mount versus the lens barrel (and camera) to get portrait orientation. That would solve the weight/balance problem but introduce the problem of a completely different process of getting vertical rows.
