- Impressive image quality for the price
- Very Good service
Optical quality and build are surprisingly very good for the price.
I did quick check for quality and crunched some numbers
I love the ED (extra dispersion) Objective Lens; usually found in high
end digital camera lenses and they have high quality BAK-4 Porro Prism.
Apparent Field of View is 4.8 degrees with an exit pupil of 4.7 mm
which great as human eye is around 5mm and it has an Adler index of
125.5, which is very good when comparing to other Bino configurations
that have different magnifications and objective lens.
They are not that heavy to hold compared to other brands.
You don't need a tripod, as long as you hold them near the front of the
objective lens, elbows tucked in to chest to form a stable triangle and
you'll be right - easy !' (Posted on 6/10/2017)
