Olympus Binocular 8x40 S - Ideal For Nature Observation, Wildlife, Birdwatching, Sports, Concerts , Black

Product Information

I use single-use lens wipes. I try to do this sparingly because you really never know if there is a tiny grain of something on the lens that will scratch. I have taken waterproof models and dunked them before wiping them down, but this is still a risky thing. Do you have any advice on how to keep your binoculars safe and clean when in the field? Image stabilisation (IS): This is where the image is electronically steadied and can be useful when birding by boat, etc., but in general IS binoculars produce an inferior image. Magnification is how large the image will be through the binoculars vs. your naked eye. In the example of 8x42, an image would be eight times larger than what you would normally see. Magnification also impacts the depth of field, your field of view, and the overall brightness of the image. Magnification also magnifies movement. The higher the power, the harder it is to hold steady. Above 10x, you will probably need a tripod system. We discuss the depth of field and field of view in more detail below. Zeiss SFL 8×40 Binoculars are “SmartFocus and Lightweight”, designed specifically to have great performance and brilliant optics. Their technical abilities include an impressive field of view up to 140 metres@1000metres and a close focusing distance of just 1.5 meters for those observations a little closer to home. Their exceptional colour reproduction makes it possible to reliably identify species across the entire focus-range.

Exit Pupil: Magnification and the size of the objective lens determines the size of the exit pupil. You can see the exit pupil by holding the binoculars at arm's length and looking at the eyepiece. That round dot of light is the exit pupil. To compute the exit pupil, you divide the diameter of the objective lens in millimeters by the magnification. For our 8X42 binoculars, we would divide the objective lens 42mm by the magnification 8, or 42/8 for an exit pupil of 5.25. If we look at a pair of compact binoculars, say a pair of 8x25, we would have an exit pupil of 8/25=3.125. This bright, sharp, and reliable model from the Olympus Pro lineup (a new 8x42 version is also available) feature nano coating for the first time in the range. Olympus is renowned for its optical expertise, so it’s no surprise that we get the same high-performance Zuiko optics that it deploys with its camera systems. Indeed, the claim here is these binoculars' optics offer unprecedented light transmittance for their class. Will they suffice or do you need a more expensive pair? That depends on what you're after. Equipped with 10x magnification and 50mm objective lenses, the UpClose G2 10x50 are both powerful and fast, offering plenty of magnification and also able to collect a lot of light. I saw a tiger shark take out a baby albatross that swam a little far out of its comfort zone near Midway Atoll in Hawaii. The boat captain let us take turns with a pair of decent Nikons, if I remember the brand correctly. I wish I had brought my own! Do you have any tips for bird and wildlife watching?

Twilight factor is computed by multiplying the objective lens diameter by the magnification and then taking the square root of this product. Thus an 8x42mm binocular has a product of 336 (8x42=336). The square root of this is 18.33 (√336=18.33). This number may seem reasonable when comparing an 8x42 pair of binoculars with a twilight factor of 18.33 with an 8x25 pair with a twilight factor of 14.14. The twilight factor really only comes to play when looking for binoculars to use during twilight or for astronomy. Again, this formula also doesn't consider the optical quality that has a tremendous impact on the perceived brightness of the optics. We selected bestselling binoculars for bird-watching from popular brands and retailers to be put through our tough tests. We buy every product we test. With a durable, high-quality finish resisting any nature conditions and a rubber coated grip ensuring a safe hold these binoculars are well equipped for outdoor use. Most binoculars offer somewhere between 8 and 12 times magnification, as this is generally the ideal range for bird watching and general wildlife viewing. Beginners should probably veer towards the lower end of this range. While greater magnification makes for a more close-up view, it also presents a few issues. The first is hand shake. At larger magnifications, any twitch of the hand becomes much more noticeable and can make the image appear blurry as a result. As you use binoculars more and more, you'll likely adapt and figure out how to reduce hand shake, but you'll probably want to start out with a more forgiving magnification. Make being in the outdoors your priority with the Zeiss SFL binoculars. The magnesium housing of the binoculars is lightweight and long-lasting, ensuring they can be passed down the generations for everyone to enjoy.

Diopter is the adjustment that allows you to match your individual eye strength. This allows a sharp image in both barrels of the binoculars if you have eyes with differing clarity of vision. Note, only one side (or barrel) of the binocular has a diopter adjustment. To adjust your diopter, use the following instructions: Not necessarily – higher magnifications exaggerate even small movements of your hands, and bigger objective lenses make bins heavier and harder to hold steady. So, most birders opt for a happy medium. Can I mount my binoculars on a tripod? Some binoculars, especially larger sizes, have a tripod mounting, but it is far from standard. Are binoculars waterproof? Knowing your terminology is important, so let's go over a few things you should know. The first thing you're going to see is some numbers like this: 8X42. The first number is the magnification; the second number is the objective lens size. We will talk about these two items first. Do not forget your binoculars at home. This is poor form every time. Are there any other things that you think are important to consider when choosing a product that we didn't cover?Relative Brightness is the exit pupil squared. The relative brightness has no relation to how bright a pair of binoculars will be. The quality of the optics has more to do with the brightness of the binoculars than exit pupil size. With the lightweight construction of the CL Companion binoculars and the impeccable build quality, you can be sure your investment will withstand the test of time, which is what you would expect as these are far from cheap. But I say you get what you pay for and the optical quality of these binoculars is possibly the best on the market.

The convenient proportion between objective aperture and magnification makes observations during dawn phasespossible. Diopter adjustmentand foldable rubberized eyecupsare included. The handy and touch-proofed surface of the BRESSER Hunter 8x40provides a comfortable grip. The tripod connectionis standardized for these models. Robust, waterproof mid-sized body: incredibly precise build and design that offers protection from outdoor elements. features a waterproof/fogproof, rubber-armoured, polycarbonate housing. comfortable twist-up eyecups with multi-stop function ensure proper positioning of the eyes for eyeglass wearers and non-eyeglass wearers alike These Olympus 8×40 S binoculars are the perfect companion for observing nature, sport, wildlife and bird watching.Objective lens diameter – the measurement of the lenses at the end of the binoculars where light enters them (measured in millimetres). The larger the measurement, the more light the binoculars can take in, making the image appear brighter (all other factors being equal).

If price isn't a concern and you just want the best optical quality on the market to date, then this pair of Swarovski CL Companion 8x30 compact binoculars are just the thing to let you observe wildlife from as close to 3 meters all the way up to 132 meters – with crystal clear vision. The second number in the bin world represents the lens diameter of the outer lens; this represents the amount of light let in for a clearer, sharper image. This becomes important at dawn and dusk. If you are just shopping for the best deal and want an inexpensive product, ensure that the second number represents at least five times the magnification: so "40" is most frequently associated with 8x , and "50" is most frequently associated with 10x. This does not mean the second number needs to be even or odd, so go for the "8x43" or "10x54" if you like. What is the most important aspect that you wouldn't compromise when buying a pair of binoculars? The second problem posed by larger magnifications is a narrower field of view. While it's unlikely you're going to find a bird or other critter that won't fit in even a 12x pair of binoculars' field of view, getting that critter framed in your binoculars is another story. While it seems simple, seeing something and then raising binoculars up to your face and getting them trained on that exact thing is a skill in and of itself. Beginners often have trouble getting a bird within their binocular's line of sight, even when they can clearly see where it is with the naked eye. A wider field of view is more forgiving in such circumstances. You will get better at this the more you use binoculars. It is very common for birders to get an 8x pair as their first binoculars and then a 10x or even 12x pair as their second. newly upgraded universal phone adapter fits all smartphones; 360° swivel and 2.2＂ extendable tripod w/ adapter ensures stable photo shooting. the ideal gift for father's day and children's day. ideal gift for outdoor. the ideal binoculars for boys and girls Best binoculars for horse racing and other sports: Sports tend to happen during the day, so a bright objective lens is less of a concern. Something like an 8x30 will hit the spot, as the 8x magnification should be plenty to see what's going on from the stand. There's no point getting something big and heavy if you don't need it!Read our full Celestron UpClose G2 10x50 review for more details Best for Ruggedness What are the best binoculars? Best binoculars for astronomy: If you're planning on stargazing, we'd recommend a binocular size of around 7x50. The 7x magnification will work well for Astro viewing as a compromise between the field of view and magnification, while a 50mm lens will provide plenty of light transmission for spotting fainter celestial objects.
