New Fully-multi-coated optics

Fully multi-coated lenses serve the essential purpose of maximising
the amount of light passing through a lens, thereby prevent flare and ghosting from interfering with your view. PeNtAX applies multiple layers of coatings to every surface of every element and prism in the full sport Optics line-up. these fully-multi-coated optics assure the maximum light transmission resulting in a clear, crisp view of the world.

BaK4 prisms

Due to its outstanding refractive index, the BaK4 glass prism found in all PeNtAX sport Optics is highly acclaimed for its perfectly round exit pupil and clear, unvignetted image.

Aspherical lens elements

edge-to-edge sharpness is a vital element to comfortable viewing. to achieve this, we utilise aspherical lens elements in our eyepieces. this is a specially shaped lens design that reduces aberration to a minimum. 

Inner Focus Optics Design

this sophisticated optical design is critical to low-maintenance and long life guarantee. exposure to airbourne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the housing and disrupt functionality.

Other Features

Helicoid three-stop eyepiece rings that permit fine adjustment for maximum viewing comfort

Exterior rubber coating that provides the binoculars with superb resistance to shocks and impacts.

Could be great
Wednesday, 8 September 2021  | 

Fantastic format and quality feels great. However I was unlucky with the specific binoculars I received and did not realize in time. They always had a little double vision, but I assumed this could be adjusted when I got around to it. These cannot be adjusted and since I didn't realize until after 18 months FLO could not help. The 24 month warranty does not cover this type of issue for the whole period. Alignment at a local shop costs more than what I paid for them so they had to be discarded basically unused. My bad and my loss.
If they had been aligned from the factory it would be an easy 5 star. Surprisingly good optics and the zoom is smooth. It's really great to acquire an object and then zoom in on it.
Recommended, but check alignment thoroughly as soon as you receive it.


Response:

Binoculars don't lose their collimation without receiving a knock so this isn't generally covered by manufacturers warranty. If they are received out of collimation then we will collect and replace them straightaway but after 18 months, this is usually caused by an impact or damage of some kind.
