Kowa GN33-8 overview

  • 1Description

The Kowa 8x33 Genesis 33 PROMINAR XD Binocular strikes an ideal balance between power and portability with a moderate magnification and objective lenses that push them almost into the full-size category. To improve image quality and boost the light gathering abilities are complementary technologies that include the use of PROMINAR extra low-dispersion glass, anti-reflection fully multi-coated optics, highly reflective C3 prism coatings, and phase-corrected prism coatings that work together to produce crisp, clear, and bright high-contrast images with accurate color rendition. Added to this performance is a wide apparent angle of view and a long eye relief, which produce an immersive observational experience for any user.

Designed for extensive outdoor use, the aluminum alloy chassis is wrapped in a protective rubber armor, and the body is ergonomically designed to offer a comfortable feel in the hand with a secure, slip-resistant grip. The optical tubes are nitrogen-filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature or humidity changes. Tethered objective lenses and a one-piece ocular rainguard ensure that the lenses stay protected while being near at hand for fast use.

    Kowa GN33-8 reviews

    8x33 Genesis 33 PROMINAR XD Binocular is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Solid glass without the European markup Color fidelity is vivid, with edge to edge being sharp. These binocular's match up with fit and finish of any top grade Swarovski or Leica. Very compact, with quality glass in a sturdy rubber on top of magnesium housing. Waterproof, nitrogen filled, many of the same features of binocs that retail for hundreds more. Highly recommended for compact/light weight binocs for hiking/birding.

    Rated 5 out of 5 by from AS GOOD AS LEICA OR ZEISS Believe me, These are as good as Leica, Zeiss or Swarovski, I like those other binoculars too do not get me wrong. However these cost half of the other European brands, and the image through these are superb and crisp and clear. I have owned my Kowa Genesis for 4 years now, with no problems in mechanical or optical workmanship. They served in bad and good weather looking through them here in Colorado. Views of misty mountains, Snow cold days fur detail on Elk and other wildlife and panoramic views with the 420 ft. field of view on these. I had a chance to compare these with a Zeiss FL 8x32 victory for a day and I guarantee if you compare these 2 binoculars you will see no difference at all in optical quality and resolution. You will see a big difference in price, I like them both but I kept the Kowa because they cost less and are built just as good. Excellent pair of quality binoculars for the price, give these a try I think you will be surprised how good these really are.

    Rated 5 out of 5 by from The best at flare/glare control, super sharp view There are four binoculars in this class: Leica Trinovid HD, Zeiss Conquest HD, Meopta Meostar B1, and Kowa Genesis. I have not tried the Meostar because the close focus is out to 5.6ft (1.75m). Here is my take on the other three. Another consideration is the Zeiss Victory Pocket 8x25, which many birders rave about, but I have not tried (it's also half the weight of these x32s). I do not wear glasses, but I have a hard time fitting binoculars to my eyes if I want to rest the eye cup fully around my eye and not tilt or use the "brow" or "hover" techniques. My eye sight is 20/20 left and 20/10 right. I seem to mostly have a problem with the right eye and blackouts. Summary: The Trinovid HD's clearly win for close focus, but their focus speed is about 1/2 that of the Conquest HD. If your main concern is close focus, get the Trinovids and make sure you are ok with the eye relief. If you want a general-use binocular with good close focus and the ability to switch quickly from close to far focus, get the Conquest HDs. If flare/glare control is your main concern, get the Kowa - they are as sharp and clear as the Zeiss and control flare/glare better, and by a lot. I've spent a while looking for an 8x32 with good close focus. I tried a bunch of $400 USD or under and the Meopta Meopro HD 8x32 was the best for me. It has 3.3 ft (1m) close focus, which is fantastic, a pretty quick focus (about on par with Conquest), and really fits my eyes well with minimum blackout issues. The downside is it does not control flare well. The Trinovid has a fantastic 1m close focus, but I found it does not fit my eyes well (no glasses, but hard-to-fit). The negatives I'm listing here are highly subjective to me and my eyes, so for you it may workout great. I have to have the eye cups all the way out in the 4th detent where they can be removed, and sometimes they come out with the rainguard :( I have to work them a bit to fight blackouts and have to keep the lower part of the eyecup off my face. I am also not convinced it is as sharp as the Conquest, but that may be an effect of having to work them to keep my eyes aligned. So despite loving the close focus, I don't think they will work for me. Also, the focus is kind of slow, taking about 7-8 finger motions to go from 5ft to 150 ft. The Conquests really feel good in the hand and have a precision to them. They do focus about 2x as fast as the Trinovids, which I've seen others mention before but did not realize how big a difference that is. It takes about 3-4 finger motions to go from 5ft to 150ft, which can save a second or two in focusing time. They fit my eyes much better than the Trinovids and I can lightly rest the eyecups all the way around my eyes for a nice immersive view. At 4.9 ft (1.5m), it is a good close focus. The Kowa are fantastic at controlling flaring and glare from stray light. I was able to get the edge of the setting sun (behind clouds) in the view without noticing any. During mid-day, I can bring the view practically to the edge of the sun are barely notice any. I would say it is on par with the $2000 Swarovski 8.5x42 Field Pro in that regard. The Kowa do not feel quite as good in hand as the Conquest, but they actually fit my eyes better, about as well as the Meopro. I can fully rest the eyecups around my eyes and I do not feel like I'm squinting through them. It is a very relaxed view. The Conquest have a sleek, precise feel, the Genesis are a bit more cushy soft feeling and the focuser isn't as nice feeling, in my opinion (it's a metal mesh feel as opposed to ridges). I will say that the Genesis grip position is very good: the index finger aligns perfectly with the focuser. Even for my large hands, the closed bridge is not a problem. The Genesis have the same 4.9ft (1.5m) close focus as the Conquest, but the focus speed is more like the Trinivods.
