Hi Dick,
The first lenses (65/8, 100/3.5, 150/5.6 & 180/5.6) released for the G690 in 1969 were only available in chrome finish. After a few months, they were replaced by a new version in black finish. Optically, the chrome lenses are identical but the black lenses are a lot more common.
Cheers,
Sebastien
