will this sync a nikon sb-600 to a nikon d700?
I don't own either the SB600 nor the D700. I bought the SC-15 to sync my SB800 (manual mode only) with several older film-Nikons that I own (FM and FE) in addition to my D80.
If I recall the D700 has a sync connector for use with studio flashes, but when I look at the SB600 manual, it appears to not have a female sync connector. In any case, if the SB600 did, you would still not want to use this particular cable as you would lose all the i-TTL functionality. If what you're after is to get the flash off the camera, you want a Nikon SC-28 which will get the strobe off the camera and still preserve the TTL functions.
