<p>Newbie here with K-500. I bought a preowned Promaster 7500EDF just to get my hands on a flash and learn how to use it. Unfortunately the TTL mode does not work with this camera. The images are always underexposed with TTL function. However, if I use manual function with 1/1, 1/2 or 1/4 setting (depending on my distance from the object and the fill flash angle towards ceiling), the images turn out really awesome. However, the flash keeps going back to TTL mode automatically. Do you think the flash has a problem, or I am doing something wrong or there is a compatibility issue with K-500? Many thanks! </p>
