Really like it, great eye relief. Field curvature does bother me sometimes on sprawling, full fov large clusters. Toying with alternatives. Tried 20mm Pentax XW, no real dif, save e.r. not as comfortable. 21mm Denk had to press up to eyecup, though sharper for more of the fov. (Likewise 17mm LVW years ago, which was bulky, too.) What about the 24mm Hyperion? Or the 22mm LVW? Would they be viable alternatives to the 21mm Pentax? Would the eye relief comfort be as good as the Pentax or noticeably worse? How about field curvature? I'd be using it at f/5 and f/5.4. Oh, and what about their size vs. the XL?
