Best Binoculars for Everyday Use

At the cheap end, the line that matters is weather sealing more than glass. Several of the lowest-priced general-purpose models, including the Bushnell Powerview 2 and Nikon Aculon A211, have no waterproofing, and owners report internal fogging after rain or a cold-to-warm car ride. At about the same money, the Vortex Triumph HD 10x42 ($100) and Nikon Prostaff P3 8x42 ($160) are sealed and nitrogen-filled. Owners rate the Prostaff P3 8x42 highly for its sharp center, light weight and 20.2mm of eye relief, which makes it an easy first pair for someone in glasses.

From about $225 to $500 the step is ED glass and better coatings: the Celestron Nature DX ED 10x42 ($240), Hawke Endurance ED 10x42 ($330), Maven C.1 8x42 ($450) and Zeiss Terra ED pair ($500 each). Owners report cleaner edges on backlit subjects, but the 10x models in this range keep coming back to one complaint, short eye relief. The Nature DX ED 10x42 has 14.3mm and the Terra ED 10x42 14mm. The Maven's 19.5mm and the Terra ED 8x42's 18mm are the safer picks.

What makes this category different is the spread of sizes. A 42mm full-size is the most forgiving. A 30mm such as the Nikon Monarch M7 10x30 ($540) or Swarovski CL Companion 8x30 ($1,499) halves the weight but dims sooner, with exit pupils of 3mm to 3.75mm. A 25mm pocket model such as the Pentax AD 8x25 WP ($179), Zeiss Terra ED Pocket 10x25 ($400) or Swarovski CL Pocket 8x25 ($1,049) actually goes along on trips, which is why owners keep choosing them. The cost they describe is fussy eye placement and visible shake at 10x. Two specialists round it out. The Pentax Papilio II focuses down to 1.6 ft by sliding its objective lenses inward, and the stabilized Canon 10x30 IS II ($550) and SIG Sauer Zulu6 HDX 10x30 ($1,000) remove hand shake electronically. The Canon is not waterproof; the SIG is.

Several general-purpose models are out of production: the Bushnell Powerview 2, Prime and Legend 8x42, the Nikon Aculon A211 and Action EX pairs, and the Meopta MeoPro HD 8x42. They stay as reference points for used and closeout buying.
