Digital camera reviews of Canon 8x25 Image Stabilization Binoculars w/Case and Neck StrapDigital camera Review: A good binocular for light use Summary: 4 Stars
I bought these binoculars because I was just a bit frustrated with using regular binoculars. I already have a set of weatherproof Minolta binocs that cost about $200, but wasn't finding it useful because the effort required to hold it steady enough to see detail just made it fatiguing to use for any length of time
Seeing as I've had great success with Image Stabilization in SLR lens, and my point and shoot, I thought I would give this Canon a try
I like it. It's quite light for its size, and compact enough that I don't feel burdened to bring this with me for any kind of event short of a long hike up a large mountain. It does take a CR123 battery which is kind of expensive if you buy them at a department store. You should try to find them online. Many high end flashlights use this type of battery, and they are available for around $2 online. Surefire (a top flashlight brand) batteries are what I recommend and use everywhere (in my flashlights and cameras). These kinds of batteries have a long shelf life so it's no problem to buy a few extra
The main reason for this binocular is the stabilization. In reality, the Image Stabilization is actually quite subtle. You still have to do your best still to keep the binocs steady, but the stabilization adds a just bit extra steadiness to the image, enough to make a difference you can notice. You have to keep the button at the top of the device pressed with your finger...it turns off as soon as you let go of the button.
All in all, the IS works well for the natural minute shakiness of your hand but larger movements are not compensated for as you would expect. So don't expect the image to be steady if you are trying to spot animals from inside a car. If you deliberately move the binoculars side to side, you can see the mechanism doing its work as it floats and then hits its limits.
The drawbacks...
- the eye relief is only 13.5 mm...so it's not really suitable for eyeglass wearers. I find an eye relief of 16mm minimum to be very usable with eyeglasses.
- uses harder to find CR123A batteries.
- the device isn't water resistant, so you have to keep this thing completely dry
- Image Stabilization effect is quite bit more sutble than you might expect, but it's definitely effective enough to be noticeably more steady than a normal binocular
I think the future of binoculars is definitely IS. I see that Canon has a version 2 of their IS in a more expensive model, so maybe the action of the IS is improved and may be added to this model in the future. If you are a casual user who just wants an effective binocular, this is a great one to choose. Canon makes higher grades and higher magnifications for the more serious user.
Summary of Canon 8x25 Image Stabilization Binoculars w/Case and Neck StrapWith Canon's Image Stabilization Binoculars, you'll never look at the world the same way again. Canon's new 8x25 IS Binoculars are the latest model in the Canon Image Stabilizer series, and brings you outstanding optical performance and unparalleled Image Stabilization capabilities, at an affordable price. The 8x25 Image Stabilization system works by ''tilting'' a single lens element in the left and right lens barrels to counteract shake. The result is a pair of all-purpose binoculars that is 20% lighter and 25% smaller than similar Canon IS models. Weighing a mere 17 oz. the 8x25 IS Binoculars are the smallest and lightest IS binoculars to date. Combining Canon's newly developed Tilt-System Image Stabilizer technology with a rounded shape for greater comfort and non-slip holding, the 8x25 IS binoculars are perfect for any setting. Whether watching your favorite team at the local stadium, or taking a closer look at the natural world around you the 8x25 IS binoculars are a perfect choice. Optical Image Stabilizer Doublet field flattener lens Super Spectra Coating Closest focusing distance of 3.5 meters/11.5 feet Rounded design for holding comfort Whether you are sitting in the nosebleed seats of a stadium or an opera house, with Canon's 8 x 25 IS binoculars you'll get an outstanding close-up view of the action. The binoculars are designed to fit perfectly in your hands and have a rubber coating for nonslip grip and protection from damage. The focus dial is center-mounted and the image stabilizer controls are easily accessible from either hand. Canon's optical image stabilization technology eliminates shake and reduces curvature of field. The image stabilizer operates with a CR123A Lithium battery. The lenses are coated with Super Spectra multicoating that improves image quality by maximizing contrast and minimizing color smear. Image Stabilization and More With any high magnification binoculars, most users will experience frustrating image shake. Unless fixed to a tripod, image shake can render high magnification binoculars useless. Canon's IS technology is remarkably effective at eliminating this problem and is widely used by the television industry with Canon's professional broadcast quality video recording equipment. A special VAP (Vari-Angle Prism) corrective IS system sits between the objective lens group and the porro prism on each side of the binoculars. Within thousandths of a second of the binoculars being moved from their optical axis by vibrations, a detection system activates the IS mechanism. The VAP shape alters to refract or 'bend' the light path by precisely the right amount, thus fully compensating for the vibration. It is this essentially immediate response that effectively suppresses image shake. Super Spectra Coating A number of optical factors affect the brightness of an image, including the amount of incidental light that is reflected by the lens. An uncoated lens will refelect away as much as 8% of the incidentail light, significantly dimming the image. Canon's Super Spectra Coating prevents that reflection. What do the numbers mean? 15x50? 8x25? The two numbers used to describe any pair of binoculars are their magnification ? 8x, 12x, 15x and so on ? and the diameter of their objective lenses ? 25mm, 36mm, 50mm, and so on. The larger the first number is, the larger the object will appear to be in the objective lens. For instance, if you use a 10x lens and look at an object that is 100 yards away, it appears to be the same size as an object located just 10 yards away. The second number, the size of the objective lens, is important because the larger the objective lens, the more light it can admit for brighter, more detailed images, and the better suited they will be for lowlight situations.
