OK, first off I hope this is in the right section. Mods feel free to move if it isn't!
I like to photograph two main areas, macro and landscape/panorama's.
I dont have a macro rail and on many occasions have thought I could use one. Likewise, many of my pano's often have a lot of parallax errors meaning lost parts of the image and increased difficulty stitching.
Im about to order a new tripod ball head form the USA and thought I may look at ordering a pano rail at the same time. This got me thinking...
Can I use a macro rail as a pano rail to sit the lens / camera over the nodal point? On the face of it, I cant see why not. The macro rails seem more expensive than a pano rail but I suspect thats because of the screw mechanism for the small adjustments needed for macro, but essentially (I think) they both move the camera forwards and backwards over the rotation /centre point of the tripod.
If the above logic isnt flawed anywhere I can buy 1 bit of kit and use it for two purposes... sweet!
I have yet to do a multi-level pano and I know thats a whole different ball-game!
