I currently have a 30mm macro (which I like a lot) and pen port that fits the 30mm and 60mm (among others; it's the stock port for PT-EP13). I also have a 12-45 pro which has a 0.5x magnification (and a 23cm working distance). I'm considering selling / trading the PT-EP13 port and getting a 30mm port to save space. Will I regret giving up the possibility of using a 60mm? Looking at my macro shots with the 30mm, most shots are at 16-18 cm focal distance. I guess I am probably not achieving 1:1 at that distance, nevermind 1:1.25.
