New to the mFT world. Once upon a time I was shooting with a Canon AE-1. The lens that ended up living on it was a Vivitar FD 28-80mm macro zoom lens. I loved it, I could go wide and zoom in, as well as really up close all with one lens. I still have it, and did get an adapter so I can use it on my GF5. It'd probably live there too, if it weren't for the 2x multiplier. I've got the kit 14-42mm lens, which is nice, but doesn't do macro. Is there an equivalent mFT lens to my old Vivitar?
