I can answer for the AF400T. I have two of them and used them extensively with two *istD's for lots of weddings. They work just fine. The thing to be aware of is that TTL mode for DSLR's is not very reliable as far as exposure goes. If you need to shoot that way, the *istD works best with ISO 400 and middle apertures. I would suggest setting the flash to auto mode and adjusting the camera much like you do for any other auto flash. No voltage issues for the AF400T.
