Hi , I dont know if I understood well or not . (Full Frame Fisheye
(Samyang) vs Circular Fisheye (Sigma))
but , I tested both Sigma 8mm Fisheye and Samyang 8mm Fisheye on Canon
EOS 7D .
as I remember , Samyand hadnt autofocus which isnt Really necessary in
VR photography . and the overall Quality was maybe little lower than
Sigma .
in Sigma I had more Degree of View about 180*120 , but in Samyang I
had about 165 Degree on longest side .
in Canon 7D , with 1.6 size of sensor . Samyang can give you higher
Resolution . 13000*7500 , when Sigma can give you about 12000 with 4
Shots .
