Because Olympus has their Mothers Day promotion currently, it seems many of the E-M5 II bundles have decreased in price. Does anyone have experience comparing them all? Is there one that offers the best deal? I'm interested in any that include either the 12-40mm PRO or the 60mm 2.8 Macro lens. I don't care much about the included extras, but if anyone has experience with the Vivitar batteries, it'd be great to hear if they're worth it. Any advice would be appreciated.
