I actually have reasonable luck with it when using the AF400T big flash. Set the camera to ISO 400, set the flash to TTL, set the camera exposure comp to about -2 and take a few test shots to see if my exposure comp is ok. Also, shoot in Raw - buys you more latitude for the shots that are still off.
Using C1 raw converter, correcting the over/under exposure on the whole batch is a snap. This setup is used mainly for weddings - ymmv Bruce Saturday, October 16, 2004, 8:22:39 AM, you wrote: WR> ----- Original Message ----- WR> From: "Don Sanderson" WR> Subject: *ist-D TTL Flash with M Lenses? >> Has anyone played with this enough to figure it out?
