For the Aptus S and AFi backs you now have 3 options (from Leaf that is):
4.5M FW 800 (9 pin to 9 pin), part # 216-00182 cost €42
4.5M FW800/400 (9 pin to 6 pin), part # 216-00181 cost €42
10M FW800 (9 pin to 9 pin), part # 518-03115A cost €83
Aptus/ Valeo users can buy the above 800/400 one or the 400/400 4.5M that comes with a repeater as well.
All come with right angle connector on One end (the 800 if it's a 800 cable).
For the H3D backs you can get any of the 3 but you'll have to shave some rubber off the connector to fit it in and you'll only get 400 speeds.
