The Trooper is a fantastic pair of binoculars, and delivers one of the crispest and clearest images of all of the binoculars tested. The only reason that the Trooper did not score higher in the clarity rating is due to the shakiness that results from viewing images with a powerful magnifier of 10x. However, the Trooper is still an excellent set of binoculars, and we used them to follow a Moose running up the hill side in the Bridger Mountains in Montana. The focus knob on the Trooper was incredibly easy to adjust as the binoculars followed the Moose's movement for over a quarter of a mile. We never knew Moose could run that fast!
The Trooper was designed for someone with a wide face. Our lead tester is a relatively average size person at 5' 10", and we had to use these at the skinniest setting that they could reach. Also, the barrels are slightly large, so it is uncomfortable to hold the binoculars while trying to adjust the focus knob. All in all, the Olympus Trooper 10x50 is a great pair of binoculars, but they are large, and designed for those looking for a slightly larger binocular.
