e up the Oly 60mm macro this weekend. I had wanted to get the Olympus mal-1 macro arm light. The dealer only had a promaster led arm light. This one takes cr2025 batteries and seems okay. Just wondering if anyone has used the Oly and how it compares. The Oly uses the camera battery. The promaster takes separate batteries. The promaster does not seem that bright but I have not seen the Oly. Has anyone used both? How do they compare?
