Visionking 5x25 Waterproof Bak4 Roof Binocular. It also has rubber armored body for durable use.The most import is it with super big lens. We are Visionking Optical Technology CO., LTD. • Extra Wide Binoculars.
To say I was blown away by these binos would be an understatement. Were purchased for some casual stargazing - low power for easier viewing, and the wide angle to get the bigger picture. With Britain's rotten skies at the mo, I wasn't able to do much testing, but in breaks between clouds I was very satisfied with what I could see. The moon in particular was very sharp.
During the day - WOW - 5x gives more than you think - I was seeing about the same detail as I would in a 7x or 8x full size binocular. We have the same 5mm exit pupil optics here, which means bright, clear and sharp optics = to what I get from my Nikon Aculon 8x42 - yes, the visionking's optics are that good.
The wide angle is outstanding, and very sharp in the centre where it needs to be. As you go out to the edges, you will get distortion (but only if you look for it). These could be used as your main day time binocular, and again, I'm very surprised how much I can see with only 5x, and oh, those 5mm exit pupil optics - hmmm.
What I don't like is the carry case - it's more like a cheap camera bag and zipped, which can cause issues with the neck strap - a soft Velcro sachet would have been better, like you get with most binoculars.
Maybe I would have liked a porro version. The engineering is remarkable as it is - a roof prism with wide angle - never seen it before, except in expensive binos. But the porro would have been ergonomically better I feel. The problem with this roof binocular is it's quite heavy (even though technically it is compact), and can be uncomfortable after a while of extended use to hand hold. Not a big deal.
But overall, this is a fab little binocular. You could take it to the sports event and enjoy the easy wide views. Take it out to countryside and enjoy some landscape viewing, and some birding from not far away for virtually shake free viewing.
And don't forget the stars on those cold, dark nights too. The Orion region will be fantastic in November/December when it's high up in the south.
This is a very good and well made binocular. It is not commonly understood that low magnification wide field binoculars are not easy to produce with their larger prisms and eyepieces which are necessary to accept the wider ray paths. The binocular has exceeded my expectations and has an acceptably flat field for such a wide angled field of view. It is also comfortable in the hand and feels sturdy. Unusually it has a protective 40 mm plain glass element in front of the 25 mm objective which focusses internally. I intend to use the glass for sports and theatre but I have also used it to good effect to sweep across star fields in the night sky.
These may not be the sexiest of binoculars and at this price who can blame them for being slightly and I mean very slightly fuzzy at the edges. What they are is fantastic for watching rugby/racing or any sports and dare I say it theatre/concerts. I bought them entirely because I wanted a wide angle of view and they give me that in spades. They are cheap enough, small enough and rugged enough to be chucked around in the Land Rover when I'm out and about and I have no hesitation in recommending them very highly.
I love these binoculars because of the quality and extra wide view which catches more of everything that's happening.
I use these binoculars all the time and switch to my Canon 15×50is to inspect items seen on the 5x25 in more detail.
These are quality binoculars with bright clear views which are enhanced by the extra wide view and at a bargain price.
