Optisan has just released its new EVR II ED 10×42 binoculars, marking an exciting addition to its growing lineup. Known for its unconventional optics dimensions such as the 8×34 and 10×34 models, Optisan now steps directly into the mainstream field with this model—aiming to compete head-on with other major brands in the mid-range binocular market.

 

Optisan EVR II ED 10 x 42 Binoculars Review

 

This is my review of Optisan EVR II ED 10 x 42 based on approximately two months of testing. I used an early production unit (serial number TU341946) and tested it primarily in tropical forest habitats in Malaysia, as well as in open country, mangroves, and coastal environments.

What’s in the box?

The package includes:

• The binoculars

• Rubber objective lens covers (attached)

• Ocular lens covers (attached to the neck strap)
• Warranty card and thank you card

• Neoprene neck strap

• User’s manual

• Carrying case

• Microfiber cleaning cloth

 

 

Features of the Binoculars

Design

The olive-green body with black trims gives these binoculars a sleek, modern appearance. The signature silver Optisan swiftlet logo stands out beautifully, adding a touch of class and brand identity. Overall, the design remains consistent with previous Optisan models—clean and functional yet visually appealing.

Size and weight

As expected, the 10×42 model is slightly heavier than the 10×34 due to its larger objective lenses. However, it remains impressively lightweight compared to other brands in the same class. Having previously used the heavier Athlon Midas 10×50, I found the Optisan EVR II ED 10×42 refreshingly lighter and easier to handle during long birding sessions.

Lens covers

The rubber objective lens covers are identical to those on previous Optisan models—attached to the barrels and flipping down before use. They can also be detached completely if preferred.
The ocular lens covers are connected to the neck strap via a short fastening strap, reducing the risk of misplacing them.

Focusing dial

Positioned centrally, the rubberized focusing dial is responsive and easy to use, allowing for smooth and precise adjustments.

Neck strap

The included wide neoprene neck strap is comfortable and helps distribute weight evenly, reducing strain during extended use. It’s easy to attach, and there’s a convenient option to clip on a microfiber cleaning cloth.

Carrying case

The black carrying case is simple yet functional. It doesn’t have a separate strap but allows you to use the binoculars’ neck strap for carrying—avoiding the tangle of double straps common with other brands.

 

Optisan EVR II ED 10 x 42 – field performance

 

Optical quality in normal conditions

Image sharpness is excellent—though not quite as crisp as the Optisan 10×34 EVR II in side-by-side testing. This minor difference may be due to the larger lens diameter. Nonetheless, the 10×42 delivers a clearer and brighter image than the older LR ED models, marking a solid improvement within Optisan’s product line.

In short: Better than the LR series, slightly below the 10×34 EVR II, but still very impressive for its class.

Low-light performance

This is where the 10×42 truly shines. The larger objective lenses gather noticeably more light, delivering bright and detailed images in dim conditions—such as late evening or under dense forest canopy. In low-light situations, the EVR II 10×42 clearly outperforms the 10×34 model.

Magnification & wide viewing angle

Different birders prioritize different things—some prefer a wide field of view; others prefer greater magnification. Personally, I value the 10x magnification more, as I usually spot birds with my naked eyes before zooming in for detail.

For my style of birding, the Optisan EVR II ED 10×42 performs beautifully. Those who prefer scanning large areas through binoculars might prefer the 8x version for its wider field.

 

Handling

For a 10×42 binocular, the Optisan EVR II ED feels well-balanced and easy to hold. It’s light enough for prolonged use and transitions smoothly between binocular and camera work.

Neck strap

The neoprene strap adds comfort, though it tends to become damp in humid, tropical conditions. In cooler climates—such as Fraser’s Hill—this is not an issue. For tropical birding, I recommend placing a thin cloth between your neck and the strap.

Lens covers

The lens covers’ attachment to the strap via a fastening loop is practical and reduces the chance of losing them—an appreciated design choice.

Some room for improvements

While the Optisan EVR II ED 10×42 is an excellent all-rounder, a few small improvements could make it even better:

• Image Sharpness –The image quality in bright conditions could be refined to match or exceed the 10×34 EVR II model.
• Neck Strap Material – Consider offering an alternative strap material better suited for hot, humid climates, as the neoprene tends to absorb sweat.
• Lens Cover Design– The current design, identical to earlier Optisan models, can occasionally obstruct the view and may wear out with time.

 

Pros & cons:

Pros:

• Excellent low-light performance

• Sharp, detailed images for a 10×42 model

• Attractive and durable design

• Lightweight and compact build

• Comfortable neoprene neck strap with clip-on connectors

• Conveniently attached lens covers

• Great value for the price

 

Cons:

• Neck strap can get damp in humid climates

• Slightly less sharp than the 10×34 EVR II in bright light

• Objective lens cover design could be improved

If you’re a birder seeking quality optics without venturing into the high-end price bracket, this model is more than sufficient for your needs. Highly recommended!
