This Monstrous Micro Four Thirds Combo is All You Need to Be a Spy

This is what happens when you combine an Olympus OMD series camera with the Sigma 50-500mm f4.5-6.3 lens and a Kippon adapter. It's huge--but considering the 2x crop factor involved here, you're getting a heck of a super zoom lens., Essentially this lens becomes a 100-1,000mm zoom lens offering with full autofocus capabilities.
