Q: 9. Would there be any compatibility issues that I may be missing with a Sigma 150mm macro? I know that I would fit with the correct adapter but I found an Amazon review stating that it did not work with their 150mm due some shutter speed limitations.

A: It will work just fine. I've been using it with the Sigma 150mm Macro OS version (latest) for nearly two years now with no problems. I'm not sure what the Amazon reviewer was referring to (it kind of makes no sense). For best results: after you get it dialed the way you like it, change your settings either in the camera or on the flash itself otherwise things can get screwy and you'll spend a lot of time scratching your head to figure out what is going on. I recommend changing settings on the flash as it's much easier and faster.
