Key Benefits
10x magnification with a 50 mm objective gives greater detail at distance than smaller models
Porro prism layout provides a wider field of view and better depth perception than roof prisms at this size

Tripod adaptable through a standard adapter thread, so it supports long observation sessions
Available in multiple size variants including 7x35, 8x40, 7x50, 12x50, 16x50, so a brand can expand its line without new tooling
Standard coating is green+blue; all blue or all green coating is available on request
Where It Is Used
Birdwatching in open fields or meadows where high magnification helps identify distant species
Hunting and wildlife observation in daylight when a larger objective gathers more light
General outdoor use where water exposure is unlikely and fogging is not a concern
Educational and kids’ nature programs where cost and durability are priorities
Porro Binoculars WP48 10x50 Black: Retail chains building a mid-tier house brand with a strong optical performance claim
Who It Is For
- Optics brands that need a non-waterproof 10x50 model under their own label

- Outdoor and hunting retail chains building a budget-friendly line with proven optics
- Buyers who already stock other WP48 variants and want to add the 10x50 to their range
Problems It Solves
Fogging inside the barrel that occurs in temperature shifts when there is no nitrogen fill
The cost of developing a new optical system when only the size or housing needs to change
The risk of water ingress in models sold as water resistant but not nitrogen filled
Uncertain performance in cold or humid conditions due to unsealed optics
The need for a high-magnification model that does not require a waterproof rating

Compared With Other Models
- WP48 8x40
- The 8x40 is lighter and more stable hand-held but has less light gathering than the 10x50; choose based on intended use and portability needs
- WP48 16x50
- The 16x50 reaches further but is heavier and harder to hold steady; the 10x50 offers a better balance of reach and usability
- WD67 8x42
- The WD67 is nitrogen filled and IPX7 rated; the WP48 is not waterproof and will fog in temperature changes
- Non-waterproof roof models like SRB03 10x42
- The SRB03 uses a roof prism and is lighter but has a narrower field of view; the WP48 uses a porro prism and offers better depth perception
Use Guide
- Porro Binoculars WP48 10x50 Black: Adjust the barrel spacing until the two images merge into one circle
- Close the right eye and focus the centre wheel until the left image is sharp
- Close the left eye and turn the right dioptre ring until that side matches
- Fold down the eyecups when wearing glasses and keep them up when not
- Mount on a tripod through an adapter for observation sessions longer than a few minutes
- Wipe off dust and fingerprints with a soft cloth; avoid submerging in water
