A couple of issues to note. You need to be able to get a firm grip on the barrel since they need a bit of effort to operate the zoom. I put a different thumbscrew in the 2"-->1.25" adapter so I could get a good grip and tighten the brass ring well. The apparent field of view is small at both 8mm and 24mm. Think plossl-type AFOV! If you are happily using a 70-80deg 24-30mm now, the 24mm in the zoom will be a noticeably narrow FOV.
