Fisheye converter FC-E8
(I illustrate Angle (spec.: 183 degrees) and View under horizontalplane).
(for reference:Angleof FC-E8)
Measurement of E4500, and illustrate result.
Use paper, like fig. (for easy measurement).
Paste tape etc. and 2 point mark with 50 cm distance.
Take a 1st. photo near wall. Black circle is near horizontal plane oflens.
(Trim fisheye photo, actual pixels)
Take a 2nd. photo far wall. Black circle is under horizontal plane oflens.
(If Angle of lens is over 180 degree.)
(Trim fisheye photo, actual pixels)
Moving Black circle by to move camera 50 cm is:
6.8+1.3-2.7=5.4, about 5.5 cm, (11cm /100cm) about 6.3 degrees.
==> Angle of E4500 + FC-E8: about192.6 degrees.
(It has many error :-p)
Measurement of E885, and result.
Take a 1st. photo near wall.
(Trim fisheye photo, actual pixels)
Take a 2nd. photo far wall.
(Trim fisheye photo, actual pixels)
Moving Black circle by to move camera 50 cm is:
4.2+3.5-0.9=6.8, about 6.5 cm, (13cm /100cm) about 7.4 degrees.
==> Angle of E885 + FC-E8: about197.8 degrees.
