Another feature that people love about this pair of Bushnell binoculars is the PermaFocus technology, which permanently maintains distant objects in focus. Given this state-of-the-art, focus-free design, you do not need to constantly adjust the focus to get a decent view.

The binocular lens coatings mostly add to the light transmitted through the lens. Hence increases the brightness, saturation, and contrast of images with better color reproduction and color fidelity, where contrast means the difference in luminance between adjacent bright and murky areas. The higher the contrast is, the sharper and more brilliant the imaging is perceived to be. It will help if you look for fully multi-coated lenses, as they have several coatings on all air-to-glass surfaces with different refractive indices. The fully multi-coated optics being on the high-end ensures the amount of reflected light to its lowest. At the same time, it considerably increases the optical performance and ensures impressive low-light performance. Last but not least, the fully multi-coated lens also guarantees the absence of any chromatic aberration. Eye Relief

I bought the Vivitar Classic 4x30 Binoculars because I plan a trip soon to the Gulf Coast to birdwatch. However, this binocular didn't work for me because the lens is not adjustable. I have had three operations on one of my eyes, thus losing quality of sight in that eye, and I need adjustable lenses in binoculars.

As we know, everything has two sides, and nothing is perfect. So here we have pointed out some of the shortcomings of the 4×30 binoculars that should be kept in mind while deciding whether you will settle for this pair of binoculars. For indoor sports, it is recommended to use a pair of binoculars offering a magnification of 4x to 8x, so you can easily use 4×30 binoculars to view your favorite basketball or table tennis match. Concert Halls These are a fairly unique pair of binos in today s market. The low magnification - in reality about 3.5x combined with a wide field and acceptable levels of field curvature are not obtainable elsewhere. I have used them a couple of times for operas where the stage is too far away to see any features on singers faces - they bring it close enough to really get involved you see the emotions and feel close up but you still see enough of the stage to get the overall production. Normal opera glasses and small magnification binos may be sharper at the edges but either they don t magnify enough or you can lose the sense of what is going on as things are happening outside of your field of view. It s a shame they don t have individual focusing eyepieces or diopter adjustment but for the price that s OK. Until pentax or someone steps in with a premium product these are worth every penny.
