I just aquired my mom's old Pentax MG and Pentax AF160 hot shoe flash. The flash doesn't work I just found out because the batteries we're left in it and corroded. A friend let me borrow his hot shoe flash to take some indoor pictures so I wouldn't end up with a yellow tint to all of the pictures. I don't know what kind of flash it was but it was bigger than my little Pentax. It made taking pictures very awkward. Can you recommend a small hot shoe flash and a filter that i can use inside so I won't even need a flash in those situations.
