The best way to handle this would be purchasing a roll of slide film and going out with your camera and shooting. With my gear, while ramp shooting I usually set a -0.3 comp. since I find the slides to be slightly overexposed if I don't. It's probably fine at full program mode but I prefer the look of the -0.3. So, my suggestion would be try the F70 at full program, look at the slides when they return and you decide. This is of course talking about shooting in full sun with a 50mm lens (or 28-70, set around 50mm). With different lighting conditions and/or weather, thats where years of experience would help you determine what settings are needed.
So, get that first roll and give it a shot. Yes, its different than print film but it's not as hard as you might think. It might be disappointing at first (you should see some of my first batches of slides) but don't give-up.
