The pc socket provides a simple X sync. There is no other information
exchanged except when to fire the flash. The TTL circuitry requiresmore
terminals and, on the F3, these connections are only available on the shoe
around the rewind knob. Depending on the model of flash, Metz might make an
adapter to allow the TTL function to work on your flash with the F3. Check
their website. There is no way to use the SB-28 as a TTL flash on a F3
period.

When you switch the flashes to TTL, they are not working correctly because
they are receiving no TTL info from the camera. Therefore the recycle times
are not indicative of what you might expect if the flashes were correctly
connected to a camera they are able to work with.
