Because I don't prefer the physical dimensions of the Hyperion zoom, I went looking for a review comparing it to the more common 8-24mm zooms to see what I'd be missing out on optically. FOV aside, according to the review below the Hyperion falls behind the Televue/Meade(and therefore Vixen). I'm wondering if that matches the experience of other users here.
