US company Maven is by now a well-known player in the market for outdoor gear and sports optics such as riflescopes and binoculars. Looking at their website, brochures and marketing material, the target markets seem clearly to be hunting and wildlife observation.
Now, Maven has come out with a new "B.6" series of binoculars in the formats 10x50 and 12x 50. The B.6 are Maven's first binoculars with 50mm objective lenses - a format which traditionally has neither had much appeal for hunters, who seem to prefer either smaller (8x32, 10x42) or larger (8x56, 10x56) binos, nor really to birders. As far as I am aware, 10x50 and 12x50 is more often found with hobby astronomers. Is Maven entering that market now??
I had been intrigued by what looks like really attractive specifications of the B.6 models and ordered the 10x50 version.
This was my 4th purchase from Maven, and it confirmed the excellent customer service for which Maven (and UPS for delivery) is famous: they dispatched on the day of my order (it then took the parcel exactly 4 business days from Lander, Wyoming to my home in Switzerland, including customs clearance), and when I found that the objective covers were missing, Maven dispatched those again on same the day of my enquiry and they arrived within another 5 days).
2.
I compared the Maven B.6 10x50 with 6 other very good 10x50s to which I have access:
and, for the sake of completeness, I added data/specs for 4 additional good 10x50s to which I have no direct access (although I do know Razor, Passion HD, Pentax and Kite Ibis binoculars, but in sizes other than 10x50):
3.
Looking at how the Maven B.6 competes on paper, its specs look impressive. It is the smallest and lightest, yet it offers excellent optical parameters, even when compared to competitors twice its price.

What looks good on paper looks even better in reality, both at home and out in the fields.
A. GENERAL
- External Finish, Build Quality: very good; armour sits tight, no gaps, everything appears high quality
- Pleasant haptics
- Grip: good to very good, both in dry and wet conditions
- Balance, ergonomics: binocular is well balanced, neither front- nor back-heavy. There is almost no thumb-trough, but when grabbing the bino, position of hands feels natural and comfortable, index finger easily finds focus wheel
- Weight: surprisingly leightweight for a 10x50 (thinner body armour than on some other binos, and body made of magnesium), feels and looks almost like a solid 10x42
- Accessories: neckstrap, eyecaps and objective covers are included; no solid bag, though, only a soft pouch.
B. MECHANICS
- Central hinge: neither too stiff nor too loose; easy to adjust. The range of adjustment starts at 58 mm, which is a bit more than on some other 10x50s, so people with very narrow lateral eye distance need to check whether this works for them
- Eye cups: Fold up/down with 4 positions (fully in / fully out / 2 intermediate click-stops). Click-stops could be slightly firmer, but do hold position well. Soft rubber eyecups are comfortable on eye sockets and nose.
- Focus mechanism: medium fast (no as fast as e.g. Maven B.2), good balance between speed and easily finding focus. Direction of rotation from near to infinity is clockwise. Focusing is very precise, smooth, even and consistent between the two tubes. There is lots of extra travel of the metal focus wheel beyond the infinity position.
- Diopter adjustment: The „0“ sign on the right tube marks true zero diopter adjustment between left and right eye. It works evenly and precisely with no play. The mechanism cannot be locked, but operation is sufficiently stiff to prevent unintended adjustment.
C. OPTICS IN GENERAL
- Quality of antireflection coatings appears high, judging from intensity of reflections. The exit pupils appear round, there are no false pupils or other bright structures, reflections etc. around them. Vignetting is relatively modest.
- Ease of view (“Einblickverhalten”): good; it is easy to comfortably position the eyepieces against your eye sockets, allowing to view the entire field of view with no shadows, “kidney beaning”, or similar effects in the image.
- Eye relief: Technical eye relief (measured from the surface of the eyelens) is 18.1 mm according to specs, “usable” eye relief (measured from the rim of the eyecups in their innermost position) is 15.5 mm. That is sufficient to use the instrument while wearing glasses
- Close focus: with 2.1 m not superb, but probably sufficient for most users.
- Field of view: RFOV is 6.5 degrees, AFOV 65 degrees. These values put the B.6 right in the middle of the comparator group of 10x50s. None of the competitors has a much wider field, some have a clearly narrower FOV.
D. IMAGE QUALITY
- Sharpness (distinction of small details) and contrast (differences between bright and dark areas) are very good in my view. Brightness is outstanding, image “brilliance” reminds me of the EL SV. The class leading transmission rate (94.75 %, according to specs, although no details are given about the range of frequencies for which this number is valid) ) seems to pay off.
- Off-axis sharpness: the sweet spot appears quite wide, slight blurring becomes visible only in the outer 20% of the image, but remains modest throughout. Not as good as flatfield binos such as EL SV or Fujinon, but better than e.g. UV HD+ and MeoStar. Overall very satisfactory.
- Distortion characteristics: I can perceive a little bit pincushion distortion; panning is smooth and comfortable, with (for me) no globe effect visible.
Field curvature is very modest.
- Chromatic aberration: that was a concern of mine, given the short build of the Maven. But CA is very well corrected, almost not perceptible at the center of the image, slightly visible towards the edge of the image. Again a good performance.
- Stray-light / glare / etc: excellent suppression of stray-light in all my tests, including artificial and natural light sources within and outside the field of view, with and without direct sunlight on the front lenses, no “wash-out” of the image, even in twilight situations.
- Flares, Spikes: no flares even on very bright light sources, whereas spikes (reflections at the roof edge) are clearly visible but do not excessively disturb observation at night
- Color fidelity: excellent. For my eyes, the image appears very bright and natural, with no significant tint of any kind.

“Mini side-by-side comparisons”
Of the 6 10x50s which I put side-by-side on a tripod and compared with the Maven,
In the market, the B.6 is more likely to get compared with roof prism binoculars, but I wanted to include 3 well-known porro 10x50s in the comparison, since these are widely used today, at least in the astro community.
Conclusion
Is the gap between $1k Japanese and $2.5k German / Austrian optics getting smaller?
I know two other instruments from Maven, including the very good B.2 11x45, but I have not been as impressed by them as by the new B.6 10x50. At a price point of $ 1’000, I get close to premium performance in most relevant disciplines and an overall very “well rounded”, attractive binocular.
Market reaction is a thing that is hard to predict, but I suspect that many people will share my impression once they had a B.6 in hand.
I would welcome comments from colleagues who may also have tried the new Maven 10x50.

“Mini side-by-side comparisons”
Of the 6 10x50s which I put side-by-side on a tripod and compared with the Maven,
- 3 are central focus roof prism
- 1 is a central focus porro prism
- 2 are individual focus porro prism
- 4 feature ED glass, 2 don’t
In the market, the B.6 is more likely to get compared with roof prism binoculars, but I wanted to include 3 well-known porro 10x50s in the comparison, since these are widely used today, at least in the astro community.
- Maven B.6 and Swarovski EL SV
The EL SV 10x50 is regarded by many as the best 10x50 on the market. It costs 2.5 x as much as the Maven; nevertheless, the Maven competes bravely with it. Brightness, central sharpness, color fidelity and CA correction are amazingly close in my eyes; but off-axis sharpness is of course significantly better in the flat-field Swarovski. The EL SV’s FOV is only 0.1 degrees larger, hardly perceptible even side-by-side. Thanks to the superb edge sharpness, the Swaro “wins” the competition for “best image” when viewed side-by-side on a tripod; however, panning is more comfortable for my eyes in the Maven which has less of a globe effect. And again, the Swaro costs two and a half times the price of the Maven.
- Maven and Meopta MeoStar
I am a big fan of the MeoStar line of binoculars and love them for their nice and relatively “warm” image, good contrast, ease of view and their robustness. Side-by-side with the B.6, the image in the Meopta shows quite a yellow tint, the image in the Maven is much “whiter” and more brilliant. This leads me to the impression that I see more fine detail with the Maven; also, the Maven is slightly ahead in edge sharpness, despite its slightly wider FOV. In addition, I have the feeling that finding sharp focus is somewhat easier in the Maven with its very precise metal focuser. The MeoStar exhibits a bit more field curvature than the Maven and. As far as I can see, the 10x50 MeoStar does not figure on Meopta’s website anymore, but it is still available in many places; prices for the MeoStar and the Maven are relatively close.
- Maven and Leica UV HD+
Like in the comparison with the Meopta, the Maven shows a clearly “whiter” and more neutral image than the UV HD+. The Leica is a superb binocular in its own right, with its perfect design, great color-saturated image, perfect focuser, and unique “Leica feel and smell”. It has a bit more FOV than the B.6, this however only shows side-by-side; for observers wearing glasses, the Leica’s usable eye relief is a bit tight. Like the EL SV, the Ultravid costs roughly 2.5 times as much as the Maven; I love the Ultravid, but have to say that the Maven competes very well with it in my eyes.
- Maven and Fujinon FMT-SX2
Central focus non-flatfield roof vs. individual focus flatfield porro: The Fujinon has earned an excellent reputation, mainly among astronomers, and is formidable instrument for many uses. Same FOV as the Maven, with a wonderfully bright image but, compared to the Maven, a slight yellow tint, clearly more CA (no ED glass), the Fuji is a large and heavy porro glass, probably rock solid. Also, its edge sharpness is ahead of the Maven, so for uses where edge sharpness counts, but weight and size and individual focus are not an issue (astro), I might prefer the Fujinon which sells at prices bit below the Maven.
- Maven and Docter Nobilem
The Nobilem goes back many decades, its design originated in the Zeiss Jena era, but it is still a wonderful instrument today. It features the widest FOV of all binos in this comparison, has central focusing but isn’t fully waterproof (like all the others). Its short usable eye relief may be an issue for spectacle wearers. The Nobilem exhibits a minimal yellow tint, but shows good contrast and good central sharpness. The Maven is ahead in edge sharpness, CA correction (no ED glass in the Docter), image brightness/brilliance and color fidelity.
- Maven and APM MS ED
The “APM MS 10x50 ED APO” is an insufficiently disguised Chinese clone of the Fujinon FMT-SX. It has been on the market for several years and has been well received, mainly by hobby astronomers; at half the price of the Fuji, but with ED glass, it represents incredibly good value, even if it’s eyepieces don’t turn as smoothly as those on the Fujinon. But is large and heavy and features individual focusing, so may not be first choice for some usages. It has clearly better CA correction than the Fujinon, but no better than the Maven, and the latter is ahead in terms of color fidelity and brightness of the image. On the other hand, edge sharpness is a bit better in the APM, which has been designed with the astro markets in mind.
Conclusion
Is the gap between $1k Japanese and $2.5k German / Austrian optics getting smaller?
I know two other instruments from Maven, including the very good B.2 11x45, but I have not been as impressed by them as by the new B.6 10x50. At a price point of $ 1’000, I get close to premium performance in most relevant disciplines and an overall very “well rounded”, attractive binocular.
Market reaction is a thing that is hard to predict, but I suspect that many people will share my impression once they had a B.6 in hand.
I would welcome comments from colleagues who may also have tried the new Maven 10x50.
