AF is, of course, auto focus. TTL, used in referring to flash, is Off-Sensor (or film) Flash Metering. A camera with I-TTL or E-TTL (different companies use different prefixes) and a compatible flash is an excellent combination for creative control. The camera actually controls the flash so your selection of f-stops is whatever you choose within the capabilities of the flash.
Before Minolta invented TTL way back in 1981 with the introduction of the X-700 and X-570 cameras and the "PX" series of flash units, you were usually limited to 3 or 4 f-stops when using a flash.
Buy the top of the line flash offered by your camera company for your camera. Buy a good off-camera flash bracket.
READ & STUDY the Owner's Manual for the flash and the section on "Using Flash" in the manual for your camera.
EDIT: As I said, Richard D, buy the flash made for your camera and there will not be compatibility problems.

Also keep in mind - not all flash units support AF / TTL, and not all cameras support it either.
