I’ve handled and looked though the Leica APO-82 spotter. Typical Leica indestructible build quality, and I really liked how it handled. With the inclusion of pure fluorite crystal, the optics are superb. I’ve always loved Leica’s color trueness and vivid image. The downsides are - it is a pretty old design (over a decade I think) and the eyepiece is limited to 50x magnification (they also sell a pretty slick doubler). So, it was really diffIcult to fairly compare it to Meopta, Kowa, and SwarovskI. Overall I liked it but the limited magnification and price pushed me away.
Just recently spent months looking for the best value/performance high-end spotter. Quickly eliminated Vortex, Leica, Zeiss, etc - and eventually narrowed it to Kowa 883, Swaro ATX 85, or Meopta Meostar S2 (or its Cabelas clone). Loved the Kowa‘s image but the non-armored housing was a huge turn-off that I just couldn’t get past. The Swarovski ATX is just plain fantastic - great ergonomics and image quality second to none - but the near $5k price tag pushed me away. That leaves the Meopta Meostar S2 - fantastic ergonomics/components/build quality, and an image quality very close to the Kowa and Swarovski. Found out that Cameraland had S2 case-demos on sale for $1799. That’s way too good a deal to pass up, bought one yesterday.
