Probably not, but why use autopano-sift-c?
Because cpfind crashes on some images (see my last posting).
I gave cpfind a try on a scenery with a sea, a city, hills, trees, rocks
and it created only some controlpoints, preferrably in clouds where the
highest contrast is.
autopano-sift-c on the opposite created more controlpoints away from
clouds, but both failed.
And, even if your CPs are concentrated in specific areas, if you use
the right lens parameters, this should not be a problem [you only
absolutely need an even distribution and many CPs when you calibrate
the lens].
Recalibrating the lens information was a good idea. But:
[with earlier hugin versions, you can work with the full-frame
fisheye setting, but the Samyang really is stereographic!].
... using stereographic as input for the Samyang/Walimex failed for me
for a 360° pano (6 around, 3 zenith). The GL preview looked perfect, the
output from blended/fused had heavy stitching errors in the upper and
lower thirds of the image.
Reverting to full frame fisheye and reoptimizing v+a,b,c created fine
output.
Nevertheless: neither autopano nor cpfind nor panomatic generated good
points to create a somewhat useable panorama - even with the new
calibration data.
At least for my outdoor landscape (means: ground , horizon, sky) 360°
panoramas.
