Overview
An 8x42 configuration puts the Opticron 30816 in familiar birding-binocular territory, in a body about 5.5 x 5.1 x 2 inches and just over a pound. That objective size is a common choice for general nature and wildlife viewing.
Opticron built its reputation on mid-range birding and nature binoculars, and an 8x42 configuration sits squarely in that segment: enough magnification to pick out detail without the shake that higher powers introduce handheld, and a 42mm objective that pulls in more light than smaller compacts for early morning or dusk use. The listing does not name the coating type or a waterproof rating, so treat those as unconfirmed.
- 8.0x magnification
- 42mm objective lens
- Center focus wheel
- 1.08 lb
Who it's for
Birders and casual nature watchers who want an 8x42 in a moderately compact, just-over-a-pound package fit the profile. Anyone specifically needing a confirmed waterproof rating or lens coating spec should verify with Opticron directly, since it is not listed here.
Strengths and trade-offs
Drawn from this product's published specifications.
- 8x42 configuration balances magnification and light gathering
- Center focus for quick adjustment
- Under 1.1 lb, easy to carry for a full day
- Coating type and waterproofing are not listed
- Only 2 ratings on record so far
Performance notes
Center focus means a single wheel adjusts both barrels at once, which is the faster setup for tracking moving subjects like birds. The 8x magnification is a middle ground: enough to resolve plumage and field marks at typical birding distances while staying steady enough to hold without a tripod.
