Kenko K-LS10-NFAB overview

  • 1Description

Kenko black Lens2scope Adapter for Nikon F Mount is a simple accessory that converts any Nikon F Mount lens into a spotting scope. Its lightweight body houses a compact roof prism, lenses, and an eyepiece just like a traditional spotting scope and with the lens is attached, the whole system acts as a spotting scope. This model features an angled eyepiece that is set at a 45° angle for more comfortable viewing while sitting, standing or laying.

The optics in the Lens2scope Adapter magnifies the image by a factor of 10x so that a 100mm lens would have the same magnification as a 1,000mm lens when viewing. Focus is easily achieved by using the lens' manual focus ring. It has a removable tripod adapter for more comfortable viewing over extended periods of time, and supports up to 28.2 oz. A small case is included to safely store and transport the adapter.

    Kenko K-LS10-NFAB reviews

    Lens2scope Adapter for Nikon F Mount (Angled View) is rated 4.3 out of 5 by 8.
    Rated 3 out of 5 by from Does what it says It does what it says, allows you to attach a lens and create a spotting scope. The resulting magnification is the focal length divided by 10. So, for example, say you put a 100mm lens on it, you get a 10x spotting scope. One thing to be aware of is that the exit pupil appears to be limited to 2.5mm. What this means is that this scope is limited to bright daylight, even if you use a fast lens. The flip side is if you use a slow lens, a cheap zoom, for example, the view can be a bit dark. So, I'd recommend using this with a lens with a maximum aperture of 2.8 or faster. This exit pupil information is clearly stated in the paperwork, but I still knock off a star for the limitation. Be aware that focusing can be difficult with some modern lenses. Turning the focusing ring on these cheap plastic lenses results in a large change. In contrast, older lenses which are designed for manual focus are much easier to use because the focusing ring travels much farther. So, this adapter is great for those old manual lenses that you don't use anymore. Finally, the cost of this adapter is similar to what you would pay for a nice dedicated spotting scope or a set of binoculars. Granted, the glass might not rival your 70-200 f/2.8, but the money is better spent. I knock off another star for value.

    Rated 5 out of 5 by from Works as you would hope I've tried this on several lenses. On an AF-S 300 f/4, it makes a nice telescope for lunar observations. On a 70-300 zoom, it makes a nice, carryable fieldscope. On a macro or a short prime with a short extension tube it makes a nice loupe. (On a 28/2.8 with 12-mm tube, it gives me a great view of the surface of a coin at 2-3 inch working distance.)The device is well marked and fits the F-mount of the lens well: snug, but not over-tight, giving a satisfying click as the catch engages. Removal is as easy as removing the lens from a camera body.There is a removable plastic foot that can be used for tripod mounting. I wouldn't trust much more than a 70-300-size lens on that. If your lens has its own tripod foot, use it.Optics in this thing seem very good. The image you get is sharp and bright, and I appreciate the fold-down eyecup since I wear glasses.One thing to be aware of: If using a zoom lens, the image will not stay in focus as you zoom. After zooming, you will have to refocus. This is true even if the lens is parfocal on the camera, such as a 70-200/2.8 or 24-70/2.8.About the only minor complaint I have is that the little cap that covers the eyecup pops off very easily. I expect to lose mine soon.Overall, this does exactly what it is supposed to and makes your photographic lenses useful for visual observation.

    Rated 5 out of 5 by from It actually Works I was impressed. It works very well. I tested it on my Nikon 200-500 and was very impressed.

    Rated 4 out of 5 by from Nice unit Appears to be well made at a very readonly price. Handy if you have a variety of long telephoto lenses to play with. One question; why put a tripod mount on the eyepiece when you need it as far forward on the lens as you can get it to balance the system?

    Rated 5 out of 5 by from Bright and good resolution I bought this because I want to use a 200-500mm Nikkor lens as an astronomical telescope. There is a Japanese company Kenko's name, but Lens2scope is not sold in Japan. I do not know why. It can be bought from importers, but it is more than double the price than B&H. I am happy that B&H sent me to Japan safely and cheaply. I saw Jupiter, Saturn. Lens2scope is bright and satisfied with resolution well.

    Rated 5 out of 5 by from Turn Your Long Lenses into a Telescope This crazy accessory works surprisingly well. Attach a 200mm, 300mm or 500mm lens to this thing, and you wind up with a very powerful telescope. This device is for viewing only. Sure, a dedicated quality telescope would offer a brighter, wider field viewing experience, but for the price, this Lens2Scope adapter does an amazingly good job.

    Rated 3 out of 5 by from Good in bright light I bought this to optimize the utility of some of my larger lenses. It works fine as a daytime spotting scope, but I was disappointed with its usefulness spoting stars.
