Canon FD Reflex 500mm f/8.0 mirror lens
introduction
this super telephoto lens is a catadioptric mirror lens introduced in 1980, and as with all such
mirror lenses, share the following characteristics:
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
3 groups, 6 elements (including mirror), S.C.C coating
closest focus 4m which gives 19cm x 28cm (7.5“ x 11.0”) field of image
no front filter thread
rear section filter holder, drop-in type (with 34mm exclusive filter. Regular 1X)
built-in sun-shade / lens hood
90mm diameter, 148mm long and 705g (compare this with 255mm and 1.3kg for a 400mm refractor style lens)
