With the recent F5 batteries threads I thought may be it is a good time to ask this. Can DB-6 really be used for the F5? I have seen this mentioned on several places including B&H's site. (http://www.bhphoto.com/photo/35mm/nikon/power.html) But the voltage seems insufficient (It uses 6 D batteries) and the connecting MC-28 cord looks like a dedicated F4 accessory. Thanks, /Isaac
