introduction
specs
500mm focal length and field of view (5°) at infinity focus (but gradually changes to 320mm when closer focus at 4m - this may be an issue with cameras where you need to set a focal length for the
image stabiliser to work optimally)
fixed f/8.0 aperture
5 groups / 7 elements
closest focus 4m which gives 19cm x 28cm (7.5“ x 11.0”) field of image
82mm front filter thread
rear section filter holder, drop-in type (with 42mm filter)
built-in sun-shade / lens hood
89mm diameter, 118mm long and 665g (compare this with 255mm and 1.3kg for a 400mm refractor style lens)
