Yet another newbie question: Does ttl mean that you can use external flash when shooting in auto and the flash measures light through the lens? Does it work on pt-023 or do I need to have an ikelite's one? I am still so new to taking photos that I don't think I manage on full manual but need to practise with the new camera (when I manage to make my mind about which camera I should get
).
Thanks a bunch!
