Parallax issues with panohead, Canon 50D and Canon EF-S 10-22mm

Hi everyone,

New to the panorama world, I'm trying to get the nodal point properly setup to avoid parallax issues. So far, while shooting indoor, I quickly see problems rising. Outdoor, with greater distance to subjects, it's going great.

I use the vertical rails on the pano head, and a Canon 50D in portrait with a Canon EF-S 10-22mm. The rails setup looks pretty good but the body looks around 5 millimeters to big to have the lens properly centered on the rotation axis. What is the solution for this ? Shall I modify the head to get closer to the arm ?

If you have other tricks for indoor panos, that will be much appreciated.

Best regards,

I described it some days before: nag away 3 mm of the rail where it slips into the mount and let it as it is where the camera is fixed. I did it with my 5D2 and it works perfectly. The rail is thick enough.

best, Klaus

If the dimension from the base of the camera body to the centrre of the lens mount is greater than 40mm, and/or the diameter of the lens barrel is greater than 40mm, then you will have to make some modification to the rail or the dovetail clamp (often referred to on the forum as the crown) if you wish to mount your camera/lens at the NPP in portrait orientation, which is necessary when shooting spherical panos indoors.

If you do not need to gain much then just using a slimmer rail may be suffiicient. You can make one from wood if you like:

Or as Klaus suggests 'attack' the standard rail with a file.

Hi Klaus & Andrew,

Thank you very much for your answers, the wood approach looks great to me, I'll see how it goes ;-)
