Using Pentax K10D with Sunpak Super 383:
Now the value of digital photography comes into play. Unless you are very experienced in using this flash it is hard to get your first shots right. You may need to take several advance shots before you get the adjustments right for your needs. The speed you have in viewing digital pictures will let you narrow down the choices quickly, resulting in superior photographs.
Simply put: it is straightly manual as it does not do pttl. You will have to do more test shots for locations with diffent light illumination. It may be ok for a small area with the same light situation. Your input confirms what I did with Pentax 280T ttl flash.
