  • Anny advices for R1 with Canon EF 8-15 fisheye, 360 at 15mm

    Hello,
    Have you some advices to take 360 panos with Canon EF 8-15 fisheye on ff camera using R1 head at 15 mm ???
    What are the recommended values for tilt and what are your NPP settings with the lens ring v2 ?
    Thanks to all

    Xavier, My advice is not to use the 8-15mm lens at 15mm. The vertical fov is only 138 degrees and you will have difficulties with the zenith and/or nadir, owing to the difficulty of maintaining a fixed entrance pupil position. Shoot at 12mm and life will be much simpler.

      My advice is to use the zoom at 15mm, and take a guess that the NPP point is somewhere near the red stripe. Set the rotator for 60 and take 6 images around. Then do two more rows 60 which will cover the zenith and nadir without any work. Keep your feet out of the pictures on the bottom row with a long cable release or a WiFi release. PTGui should stitch the 18 pictures with no effort, and a spherical projection will stitch to something around 18,000 x 9000 (depending upon your sensor size) in an equirectangular. You can upload that to Flickr and it will rotate. Flickr will take anything up to 200 Mb, but they downsize substantially for display. The Flickr viewer doesn't work on an iPhone or iPad.

        The R1 head does not have this facility.
