I read some of the limited reviews on this eyepiece, and some people seemed to find this eyepiece very similar, if not a clon of the Olivon Pro zoom.. Others think that it would be a clon of the original Vixen lanthanum, with a different body design, but most of the owners of the Olivon Pro, agree that the zoom is the same eyepiece.. This Olivon Pro, is also a clon of the Celestron Regal zoom, and this seems consistent with specifications..
I owned the Regal zoom and it is a nice eyepiece. I posted a review a while ago, and I noticed the FOV to be slightly wider than standard zooms I have used to date, but not in the league of the Hyperion Zoom, that to my standards is already a wide angle eyepiece in all the range. My copy of the Regal zoom got stuck at high power and would not zoom back, and never did, so it. became a large 60x, yes, wide eyepiece.. It is the only zoom that failed on me and probably nothing more than a bad unit, plus I bought it used, from a member here that also got it used, so we can't tell if the eyepiece was abused or what. All in all, IF is indeed the same zoom, It's a nice eyepiece, but at 200 euros, I think the Baader is a better deal.. Better built, more versatile and adaptable and offers a wider FOV with the same if not better IQ, although the image through the Regal zoom was indeed really good as well. I don't know if this is the same eyepiece for sure, but a few members in Cloudy nights pointed me in that direction after reading a few posts.
I hope some first hand reviews or opinions are added to the thread..
