Sorry, I have a few more questions! Like I said I have the RZ67 Pro, will the AE Prism for the Pro II work on the Pro I body? If so, does it take advantage of the half stops as well? Only reason I ask is because I've seen people say yes and no, would just like a good solid yes or no! haha. I found a Pro II AE prism for about $80 in pretty good condition. Thanks!
