Optisan EVR 10x42

Optisan EVR ED 10x42 binoculars deliver bright, high-clarity views for close-focus observation—designed to keep subjects like birds, insects and butterflies clearly visible at short distances. The optical arrangement delivers 93% total light transmission and a Japanese optical design that reduces edge distortion and chromatic aberration, so contrast and color stay consistent across the field of view.

• High light transmission: 93% total light transmission for brighter images in varied lighting.
• Reduced optical errors: Japanese optical design minimizes edge distortion and chromatic aberration for clearer detail to the frame edges.
• Close-focus capability: Suitable for observing nearby subjects such as birds, butterflies, and insects.
• Weather protection: IPX7-rated waterproofing and nitrogen-purged optics help prevent fogging and protect internal glass elements.
• Practical controls and accessories: Twist-up eye cups for comfortable viewing and removable ocular and objective lens caps for lens protection.

These features combine to make the EVR 10x42 a focused choice for users who need bright, low-distortion views at close range with durable, weather-resistant construction.
