First impressions optically are  huge sweet spot, decent off axis performance, cooler color bias, very good CA control, very good apparent sharpness. Mechanically the focus was excellent. Size wise I would not call them large for an 8 x 32. I would have guessed a field of view just over 400 feet if not pressed to compare them to other models. I'm guessing the impression is largely from the large sweet spot and larger oculars. Nmason, I will check out the HG's again tomorrow. Optically they were quite pleasing. Again an extremely large sweet spot but definitely not sharp edge to edge. I would believe the field flattener claim  based on edge performance. Like I said I'll try it again tomorrow and see what  like I said I'll try it again tomorrow and see what else  jumps out at me. They do have the super smooth, almost buttery, Nikon focus.</blockquote>
