Customer feedback on the new Questa binoculars
 "At about 20 feet, looking at cardinals, English sparrows, and a red-bellied woodpecker at about 60 feet, I today for the first time have seen texture of feathers.  Plus I watched with extreme clarity, the eating/shelling of seeds by the cardinals.  At about 20 feet, I can clearly see the Philips head screw pattern in the feeder.  I experimented briefly looking through the Questas with and without my prescription glasses.  I can get an excellent field of view, and even better clarity and definition with my prescription lenses.  I've not had this experience before with binoculars.  These binoculars and my glasses seem to work very well together. So, I am looking forward to my new viewing of the world around me with my Questas.  Thank you.
