 +When focusing by rail, there will be changes in magnification and perspective with all lenses.  Changes in magnification can be completely corrected by Zerene Stacker, but changes in perspective result in apparent movement that may give artifacts in the result.  See [[:stacker:docs:troubleshooting:ringversusrail|HERE]] for more discussion on this point.  For critical work, it's better to focus by ring and to choose a lens model that does not change length as it focuses.
