Kenko VC Smart Cellarto 10x30 WP image stabilized binocular review

If the makers of multiple Star Wars spin-offs are seeking an authentically futuristic binocular, they’ll find it in the Kenko VC Smart Cellarto 10x30 WP. A single AA alkaline battery powers an onboard ‘Vibration Correction’ feature (read: Image stabilization). This compensates for everything from a slight hand tremor to bigger movements, which might otherwise result in a visibly juddering image in the short term, and eyestrain in the longer term.

Usually, any image-stabilization mechanism will demonstrably add weight and bulk, as well as inflate the price. While there is indeed a premium being asked here, this binocular happily remains compact enough to squeeze into a jacket pocket.

While the letters ‘VC’ indicate built-in vibration correction, the suffix ‘WP’ further indicates a degree of waterproofing for outdoor use, whether that means observing skittish wildlife in the day, or the stars above on a cold, clear night.

While the best image-stabilized binoculars are fantastic for handheld views, the best binoculars for stargazing are typically mounted on a tripod for stability. For now, let’s take a deep dive into the Kenko VC Smart Cellarto 10x30 WP.

Kenko VC Smart Cellarto 10x30 WP review

Design & Comfort

• Ridged focus ring ergonomically placed atop lenses
• Inter-pupillary distance adjustable to match your eyes
• Protective rubber caps provided (for eyepieces only)

The Kenko VC Smart Cellarto 10x30 WP is reassuringly sturdy when gripped. It has a porro prism design and a body manufactured in polycarbonate resin. This is complemented by soft, tactile twist-up rubber eyecups to aid those either viewing with spectacles or without, plus a plastic, ridged focus wheel located above the front glass where your fingers can find it without taking your eyes off the subject.

With a flat profile and a compact enough size for stashing in a roomy jacket pocket, the binocular’s surface has a very subtly roughened feel. There is little chance it will slip from our hands, even if operated in the rain with wet fingers. That’s a real possibility, as the construction here is waterproof and fog-proof, so cold and damp nights staring at the heavens, or early morning jaunts to spot wildlife while there’s still dew on the grass, prove no issue.

Further aiding comfort and usability is the fact that the interpupillary distance between the eyepieces can be manually adjusted between 54 and 74mm to best match up with your own eyes. Ideally, what you want to view is a large, bright circle, with sharpness of image evenly maintained edge to edge. You get exactly that here.

What’s omitted is a screw thread with which to attach this binocular to a tripod. Obviously, its manufacturer feels that with stabilisation an intrinsic feature, this isn’t needed. However, it might still have proved useful in enhancing comfort during prolonged periods of observation.

At 18.8 oz (533 g) in weight, the device is not prohibitively heavy by any means, yet it has enough substance to it that it’s possible to hold it usably level and steady even without Vibration Correction switched on, should you wish to preserve the already generous battery life. If we’ve a minor moan, it’s that we found retrieving and inserting the required AA battery a little fiddly, because the battery compartment is flush up against the lens housing. But it’s hardly a deal breaker.

Optics

• 30mm objective lens delivers a sharp, bright image
• 10x magnification allows scrutiny of fine detail
• On-board Vibration Correction enables handheld observation free from image wobble/judder

As denoted by the Kenko VC Smart Cellarto 10x30 WP’s name, the core features we’d normally pay most attention to here are its standard 10x magnification wedded to a large, bright 30mm objective lens. The latter allows for clear observation into the hour of dusk and beyond. Those considering this device for looking at the moon and stars are adequately served, though a more powerful 16x binocular or scope might prove a better fit still for scrutinizing scars and craters on the lunar surface.

As expected, all lenses and prisms used are fully multi-coated to maximize light transmission and boost contrast. We’re pleased to report that views are free from tell-tale artifacts like chromatic aberration when viewing contrast-y subjects, such as the dark branches of a tree backlit by a clear blue sky on a spring day. We also didn’t experience any lens flare, even in direct sunlight.

Indeed, the clarity here is such that the view appears pleasingly three-dimensional, as if you have “zoomed in” with your own eyes rather than viewing a subject via a construction of lenses and prisms.

While sometimes built-in image stabilisation sounds like a bit of an unnecessary gimmick, especially with the Kenko “only” offering 10x magnification, in fact, its “smart” Vibration Correction feature proves very useful in practice. It automatically corrects for what its maker terms fine vibration, such as hand tremor, or large vibration, for example, panning quickly when tracking a moving subject, or using it on the deck of a bobbing boat.

Powered by a single AA battery (provided in Japan, but an extra purchase beyond its borders), up to an impressive 28 hours of continuous use is claimed.

The overall impression is that this is a well-made, high-quality product with excellent optics capable of delivering searingly sharp results in a wide variety of conditions.

What we saw

As indicated above, the Kenko VC Smart Cellarto 10x30 WP binoculars’ bright, clear optics provide pleasingly naturalistic viewing results, with their razor-sharp focus maintained right across the field of view.

When the Vibration Correction feature is switched on, a small pilot light illuminates. To avoid this proving distracting when using the binoculars at night, in a concert venue or theatre, a plastic shutter can be slid across to hide it. Clever.

As its manufacturer believes this binocular is highly suited to hobbyists who enjoy wildlife watching and/or stargazing, of course, we tried out both pursuits during our review period.

Performance with or without ‘VC’ active was impressive, though we did inevitably enjoy smoother, more comfortable viewing with the feature switched on. Having it active also enabled us to more quickly and accurately identify what we were looking at, with, for example, the yellow irises of the tufted ducks on the local pond rendered with a pin-like sharpness. While their beaks appeared white in colour when viewed with our own eyes, when viewed via the Kenko VC Smart Cellarto 10x30 WP, we could see that, in fact, they were a subtle shade of egg blue. At a normal viewing distance, the shifting colour tones when it came to their feather detail also would not have been picked up on, but with 10x magnification, they were.

Similarly, at night, with 10x magnification and image stabilisation working in tandem, we could identify scars and craters on the moon that would have been just indistinct grey blurs viewed with our own eyes. Without the ‘VC’ active and viewing handheld, stars appear to jump around and emit light trails. Flick the switch, however, and the points of light snap back into sharp, clear focus.

Yes, we might wish for greater magnification, but the decisions that have been made here with regard to size, weight, performance and price nevertheless make for a very enticing package indeed.

Verdict

What do we want from a pair of binoculars? A device that delivers an impressively sharp view under a variety of conditions, enabling us to identify various star clusters or animals/birds based on tell-tale aspects of their plumage. With the Kenko VC Smart Cellarto 10x30 WP, we get all that, along with a rock-solid build and a very practical stabilisation feature that can last up to an impressive 28 hours of continuous use off a single AA battery, kicking rivals into touch.

Our only complaints here are very minor ones. Yes, there are alternatives that could suit you better if you’ve the budget to stretch, or need a higher magnification still. But for those seeking the one binocular that does it all, stays the course and repays your investment, it does feel like Kenko has hit the sweet spot with this one.

The other subject this binocular is particularly suited to is viewing skittish wildlife from afar. We’re lucky enough to live close enough to London’s largest park with an abundant supply of deer, rabbits and various wildfowl. Again, with ‘VC’ active, this device is sharp enough for us to be able to identify various markings right down to subtly differing colour tones across an expanse of feathers, or unusual iris detail in different breeds of ducks. For the keen amateur who wants one pair of binoculars that can deliver great results in a variety of circumstances and lighting conditions, if budget allows, the Kenko VC Smart Cellarto 10x30 WP comes highly recommended.

How we tested the Kenko VC Smart Cellarto 10x30 WP

Image 1 of 1

Under the cold, clear light of a full moon, we were able to identify various craters and scarring on its surface thanks to the Kenko VC Smart Cellarto 10x30 WP’s 10x magnification and bright 30mm objective lens. While it’s perfectly possible to hold this binocular steady enough to do so without its battery-powered Vibration Correction function switched on, the view is smoother and comfortable with it active.
