Kowa Genesis 8x33: Troubador's Review (1 Viewer)

So is the Zeiss FL $600 better than this Kowa?

This is a personal decision about how much to spend JG.

I haven't seen transmission figures for the Kowa 33 but the 44 is about 6-7% behind the Zeiss Conquest, so if the 33 is similar then an FL might be worth the extra if transmission is really important to you.

But there is more than transmission to choosing bin and the Kowa (and Meopta 8x32 that I have also tested) make convincing cases for themselves.

If I was to say what could be improved on the Kowa it would be that the focus wheel could turn a bit more freely and could be a bit larger in diameter for better control, and yes, a bit more brightness wouldn't go amiss.

But Kowa, Meopta and the Zeisses are all worth every cent: you pays your money and makes your choice :t:

I have owned the 8.5x44 Kowa and currently own the 8x32 FL (and have owned the 7x42 as well).

I would personally say that the view is not $600 better; however, the focus and the eye-relief are superior to the Kowa, and it is indeed brighter early and late. I actually used the 8x32 FL for deer hunting this year and it performed great even in the low light conditions. I am not sure the 8x33 Kowa would be as pleasing in such conditions.
 
No to go too far off-topic and make this about the FL, but yes, the 8x32 FL has quite good eye-relief, the best I've found in a 32mm including the SV EL with its claimed 20mm of eye-relief.
 
I tried the 33mm Kowa at the weekend, having had a previous look at the 44mm version, which was gorgeous but about the weight of a house-brick.
The thing i'd been struck by with the bigger bin was an unbelievable depth of focus, and thus how little you had to fiddle with it. I know there is much to muscle-memory and familiarity and design, but i'd just been using a Vanguard Endeavor EDII with a flat field and a much reduced DoF, so the difference was emphasised.
I found that although the 33mm was less bright than the 44 (this week's Sherlock Holmes award, i think!), it shared that depth of focus. Both models would suit those who maybe do their birding in big environments, with action taking place at a range of distances.
I mentioned this to the retailer, and he said 'well, Kowa do great glass!'
I'd have to agree - i really liked them.
 
Lee hello and good morning, everyone, use the Kowa 8.5x 44 5 years (before I had for sixteen years a Docter 10x40), binoculars do not like change often I have to like to touch and sight, what struck me the most it was the total absence of chromatic aberration, the sharpness and contrast.
Definitely does not have a wide field of observation but I dedicate mainly raptors and has never let me down, its weight is its very stable force in hand, keep in mind that I normally I move just walk and do about 15 km at a time .
I know there are around best binoculars but at what price? I think that a person should attach their wing attrezzaturae she did not disappoint. A hug, Giorgio
 
I also apologize for going a little OT, I got hold of the Kowa 8x33, and I must say that confirms the professionalism of his older brother, now I'm used to 8.5, but if I wanted a lighter tool I would not doubt.

Good evening, Lee, there you are satisfied, this is a week spent in Sicily to help an association (www.gruppotutelarapaci.it ) that preserves the Bonelli eagle.

I think it is possible to translate directly from Binomania site. See you soon. Giorgio

Thank you Giorgio.

Nice picture of you and your Kowas and very nice picture of the Bonelli's.
Thanks for posting.

Great review. I have the genesis 10.5x44 and they are a pure joy to look through. I've had them for years and still smile every time I bring them up to my eyes. These 8x33 have been on my radar for a couple years. May have to finally figure out how to get a pair.
 
Lee
I pulled the trigger and got the Kowa 8X33's they are just as good as my bigger ones and something I can handle
when I'm carrying a Nikon D500 and a Tamron 150X600 lens. Probable the last pair I uy unless something happens to one and since Kowas are built like tanks I'm not to worried about that. Thanks for the reviews Lee they really helped with the decision.

I take it the previous comparison was between the Zeiss Conquest and not the Victory model to the Kowa 8x33, as the Zeiss Victory model appears to have a higher price.

HI Joe

The review of the Kowa did mention Zeiss Conquest HD and not Victory FL, so yes, you are correct.

Appears the KOWA Genesis 33 PROMINAR is selling for a hair under $900 to a tad over $900 from several retailers. A German firm is selling them with free shipping to the States. Is that just a promotion from KOWA or a sign of something to come?

In the UK Kowa has discounted the Genesis models from time to time, especially in the months up to Christmas, so this is not unknown by any means and it hasn't flagged up a replacement yet.

The biggest birding event in Europe, the British Bird Fair, has just finished in August and it seems unlikely that Kowa would be launching anything now or in the near future.

To most people, Kowa means spotting scopes and this is hardly surprising since they have made them since 1952 and introduced the much-respected TSN scopes in 1984 with the TSN3 & 4 arriving a couple of years later, equipped with fluorite crystal lenses for the control of chromatic aberration. Kowa has remained a force to be reckoned with in the world of spotting scopes but a few quick looks through Kowa’s binoculars at the last couple of UK Bird Fairs were sufficiently intriguing to prompt me to want a longer look at them. Kowa’s Genesis XD-33 8x33 was introduced in 2009 and is a neatly styled model equipped with Schmidt-Pechan prisms that are phase- and dielectric-coated and has what Kowa calls two XD lenses in each optical tube. These are extra-low dispersion glass elements in the 3-element objective to control chromatic aberration, but not all low dispersion glasses are created equal so it will be interesting to see how they perform. A 5-element eyepiece completes the component line-up.

This model has a very competitive specification with a field of view of 140m (at 1,000m) or 420ft (at 1,000yds) and a closest focus of 1.5m or 4.9ft. But which models is it competing against? In the UK it is listed at £952 but occasionally there are special promotion prices (there are still some units being offered by dealers at £498 or £549), so it is worthwhile checking Kowa prices from time to time, including right now for Christmas 2016 offers. If we take the list price of £952 and a band of £200 each side of this and look for other models priced within this bracket we don’t find many competitors at all. In fact I only came up with Meopta’s B1 MeoStar 8x32 at £749 and Swarovski’s CL Companion 8x30 at £775. Zeiss’s Conquest HD 8x32 for example sits below this price level at around £590. Ignoring Kowa’s occasional special price deals, this model seems to have found itself a price-niche in the UK market. It is a similar story In the States where it is being offered by dealers at around $1160, and looking for competitors priced within a band $250 each side of this we find the same two models as in the UK, with the Meopta at $850 and the Swarovski at $1029, although you might still find examples of the discontinued Nikon Premier 8x32 at $1200.

As usual we will take a look at the unit in the hand first. Subjectively, I think it is a very handsome instrument with a huge amount of visual appeal, but how does it measure up? At 133mm (5.1”) high it is taller than the Meopta B1 MeoStar 8x32 (123mm / 4.84”) or Swaro CL 8x30 (119mm / 4.7”) and more or less the same as the Zeiss Conquest HD 8x32 (132mm / 5.2”) but a little shorter than Swaro’s EL 8x32 (138mm / 5.3). At 590g (20.8ozs) it is usefully lighter than Zeiss’s Conquest (630g / 22.2ozs), about the same as the Meopta (598g / 21.09ozs) and heavier than Swaro’s CL (500g / 17.6ozs). To put all of these in context Leica’s Ultravid HD+ 8x32 is 116mm (4.57”) long and weighs 535g (18.9ozs) and Zeiss’s FL 8x32 measures 117mm (4.61mm) and weighs 550g (19.4ozs).

It feels balanced in the hand, the textured armour offering good grip even in the wet with cold hands, and the wide, shallow depressions in the armour on the back of the tubes do not get in the way or force you to adopt any particular grip but do give your thumbs a sense of their position. The dioptre adjuster is by a locking collar on the right-hand tube and is easy to use and effective. The eyecups offer 4 positions, are secure in all of them and feel nicely made with a medium-soft texture where your eyes or spectacles rest. In fact they may well be the best-feeling eyecups I have ever encountered and I had no problems at all with the 15mm eye relief either with my spectacles or viewing with the naked eye.

The neck strap is not as successful as it is not tailored to lie flat on your upper shoulders but is of the old-fashioned design that hangs from the back of your neck. This is not much of an issue when wearing a jacket with a high collar or hood but personally I find it uncomfortable when wearing just a shirt, T-shirt or sweater. Moreover this neck strap has to double as the shoulder strap when the bins are in their carrying case, and while this means stuffing your bins into the case and dragging them out again later is a much less fussy business without having to fold and unfold the neck strap, I have always thought this unsatisfactory, as the length you need for a neck strap is quite different from that required for a shoulder strap. Moreover the case doesn’t have any strap loops so you can’t even fit an aftermarket shoulder strap. By the way, the case itself is quite adequate.

The rain guard has two loops for the neck strap to pass through in the usual way but the right-hand side one is split, presumably to enable it to be quickly detached on that side. Trouble is, the deep cups that provide excellent protection to the eyepieces grip the eyecups rather tenaciously and as you pull harder to lift the rain guard up the split loop always detaches from the strap. This matters to me because I am one of those folks that likes the rain guard to be secured on both straps, but this will not be of any concern to the many, like my wife, who only attach it to the left-hand strap. I would prefer a more generous diameter to the rain guard cups so that they don’t grip the eyecups so much thus allowing a faster on and off action when caught out in heavy rain, but after-market replacements are available so it is no big deal. One plus point is that it works just fine even when closed down to the minimum IPD which is not something that every Zeiss rain-guard achieves. The objective covers attach by way of rubber rings which keep them secure and without them dangling around like those attached by a tether which can result in them tangling on thorny bushes or barbed-wire fences.

The focus wheel is unusual as it is metal, probably aluminium. Some reviews have pronounced that it is plastic but a friend tested one with a red-hot needle and believe me, its metal. It not only looks good, feels great and works well with gloves, the knurled surface is also reminiscent of the feel of the volume and tone knobs on my Fender Telecaster. You’re not impressed by this last point? OK, getting down to serious stuff, the focus action is a peach. Smooth and fluid, with just the right amount of resistance and with equal effort required in both directions, it is just superb. If mid-price models such as this, the Conquest, and the Meopta MeoStar get focus-feel so right you have to wonder how it is that the alpha models sometimes trip up over this aspect. The Kowa is fast enough for me but not too fast: from far distant (4km/2.5miles) to a 2.0m/6.6ft focus only takes around 3/4 of a turn. For comparison my Conquest HD 8x32 takes only ½ turn to cover that distance, which for me makes the Conquest more suitable for insect-rich habitats, but the Kowa is a great compromise between the speed and ease of precision required for nature observation . And the icing on the cake is that there is not a trace of slop/slack/free-play. Call it what you will, there is none of it. Excellent.

Control of chromatic aberration is exemplary, almost on a par with Zeiss FL, which means for all practical purposes you can forget about it.

I found panning to be quite free from rolling ball despite it being reported by some, but I seem to be one of those relatively unaffected by RB so those who suffer from it should check for this.

When reviewing the Kowa’s bigger 44mm brother, Holger noted that it rendered distant power lines not only finely and clearly but also in a definite black, indicating exceptional contrast and I had a similar experience with this model. The plain grey-looking flanks of a male Mallard are actually covered in fine vermiculations and my goodness the Kowa reproduced those superbly with the excellent contrast giving great definition to the fine markings. This was confirmed by observing a small white feather, floating down the river some distance away with the finest of vanes clearly delineated against the dark water behind and without a trace of chromatic aberration.

It was a moderately cloudy day when I was watching the Mallard but the clouds weren’t too heavy and plenty of light penetrated through although there was no direct sunlight. As I watched, the male Mallard turned his head from side to side, watching me and the nearby females and as he did this his head plumage caught the light and turned from deep green to a shimmering purple/blue. It was such a pleasure to watch this happen and to see the details of his plumage that for some minutes I was just lost in the enjoyment of the moment. A few minutes later I spied a Dipper on a rock on the opposite side of the river. The Kowa easily captured the delicate pattern on its mantle and the subtle plumage tones that shift from chestnut to brown while the white throat was rendered immaculately. In fact the Kowa’s colour rendition was excellent and I could not discover any undue emphasis of either red, green, yellow or blue.

Several days later I was viewing birds on nearby feeders and Grey Squirrels and Brown Rats running around underneath cleaning up food spillages. Watching the more distant rats and squirrels under shifting winter light I was struck by the apparent sharpness of their whiskers, clearly aided by the excellent contrast I mentioned earlier and which I would say is a little better than my Conquest HD 8x32, although I found the Conquest to be noticeably brighter. By way of illustrating how binoculars are such finely balanced compromises let me tell you about a different site I visited, another river with a fine selection of gulls, geese, ducks and rails. Due to the presence of many willow trees and an islet, birds were making brief appearances in my viewing area and this put a premium on speed of target acquisition and focusing. It was fascinating to pit the speed of the focus action of the Conquest (which achieved a faster coarse-focus view) against the extra contrast of the Kowa (which speeded up achieving that final fine focus). In the end it was a draw between the two.

One thing I noticed was that in special circumstances the Kowa’s extra contrast and less bright view can put it at a disadvantage. There was a large area of dark water in which there were several large stones creating turbulence that caught the sunlight filtering through the thin cloud. The Kowa rendered this area as monochrome with dark velvety water and bright white sparkling turbulence which was a delight to look at. However, through the brighter Conquest the turbulence sparkled a little more and the water was not so dark, but was more brown than black. Curious, I walked up onto the nearby bridge, and then on the opposite bank, checking out the colour of the water from different angles, and sure enough it actually was rather brown, caused by the spate resulting from the rain we had a couple of days ago.

The Kowa’s sweet spot is wide enough that I had to adopt unnatural viewing angles to examine the extreme peripheral field of view for out-of-sharpness, so to my eyes, for all normal usage, the Kowa is sharp right across the field of view. When viewing from a hide (or blind) facing the sun but partially shaded from it and looking in the direction of the sun (but not directly at it), I found that glare was apparent in the lower half of the field of view which did not appear in my wife’s Leica Ultravids. However this was a rather special circumstance in which I was viewing far closer to the sun than caution would normally allow so again, for normal viewing, this was not an issue.

Summing up, the Kowa Genesis 8x33 has a superb view, great colours and is as sharp as you could wish for, snaps easily into focus thanks to quite superb contrast, and possesses a nicely balanced speed of focus via a creamily smooth focusing wheel. Of the other models I mentioned as the near price competition, the Swarovski CL falls short when it comes to optical performance, I am not familiar with the Nikon Premier, but the Meopta B1 MeoStar and Zeiss Conquest HD are both worthy competitors.

I am sure the Kowa website and dealers can answer most questions but if they can’t you can contact John McIntosh, Kowa UK Sports Optics Sales Manager. He has spent time at both Zeiss and Leica in the past so has an excellent background in sports optics. His contact details are: Email: [email protected] & Mobile: 07904 449817.

On the basis of this model it is a puzzle why Kowa does not have as good a reputation for binoculars as they do for spotting scopes, since this model is certainly deserving of high respect and a wider audience.

Lee
Great view..very thorough and helpful. Thanks!
 
I have ordered a Kowa 8x33,still awaiting its arrival.I see this binocular was introduced in 2009,does anyone know if it’s the exact same binocular now or has it been refined a little over the years?
