One more thing: the focusing scale on Samyang 8mm lenses is often (usually?) incorrectly calibrated so you can't just set it to 1m or infinity and trust that it's actually focused at that distance. You need to focus each shot using liveview or calibrate the distance scale yourself. You can find the instructions for calibration here: https://hdrtist.wordpress.com/2011/11/11/rokinon-8mm-fisheye-lens-review/ -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
