Hello everyone! I'm considering a Z8 and have a quick question. Every time I read about the Z8, the only mentioning of the adapter is the FTZ II. Other than the body shape of the FTZ, does the FTZ II offer any advantage or is it necessary to operate with the Z8. I only have two Z-lenses (50, 24-70) and will continue to use my F-lenses. Thanks!
